The idea is to first capture the message to file and then run the

Bugfix: reorganized some code in the MYSQL client to end
a number of memory allocation/deallocation problems.
This code needs more work. File: dict_mysql.c.

+
+ Bugfix: the MYSQL client did not provide function pointers
+ for unimplemented operations, causing "postmap -d" to dump
+ core instead if issuing an error message. This is what I
+ get for accepting code that I cannot test myself.

+[Original Message]
+I've run out of time to fiddle further at the moment, so I've decided to
+post my virtual local delivery agent. Note that this is still a work in
+progress, so don't bet your business on it.
+
+I'll repeat what I said last time:
+
+ This code is designed for ISP's who offer virtual mail hosting. It
+ looks up the location, uid and gid of user mailboxes via separate maps,
+ and the mailbox location map can specify either mailbox or maildir
+ delivery (controlled by trailing slash on mailbox name).
+
+ The agent does not support aliases or .forwards (use the virtual table
+ instead), and therefore doesn't support file or program aliases. This
+ choice was made to simplify and streamline the code (it allowed me to
+ dispense with 70% of local's code - mostly the bits that are a security
+ headache) - if you need this functionality, this agent isn't for you.
+
+ It also doesn't support writing to a common spool as root and then
+ chowning the mailbox to the user - I felt this functionality didn't fit
+ with my overall aims.
+
+Some other notes:
+
+- It's still called "virtual" - I had some concerns that this would
+ confuse people, but I'll leave that call up to Wietse - if he wants
+ to integrate it, he can specify the name.
+
+- I've retained the three separate map lookups at this time. When
+ postfix supports maps that return multiple values, we can consider
+ changing it then.
+
+- Specify "virtual:" as the target in the transport table for domains
+ for which you want this agent used.
+
+- The attached file is a gzipped tar that should be unpacked in the
+ base postfix directory (where the INSTALL and HISTORY files live) -
+ it adds a "virtual" subdirectory, and a "virtual.patch" file. The
+ patch updates the top level Makefile.in to build the new agent, and
+ global/mail_params.h to add the new config parameters.
+
+New config options are:
+
+virtual_mailbox_base
+
+ Specifies a path that is prepended to all mailbox paths. This is
+ a safety measure to ensure an out of control map doesn't litter the
+ filesystem with mailboxes (or worse). While it could be set to "/",
+ this isn't recommended.
+
+virtual_mailbox_maps
+
+ Recipients are looked up in this map to determine the path to their
+ mailbox. If the returned path ends in a slash ("/"), maildir-style
+ delivery is carried out, otherwise the path is assumed to specify a
+ mailbox file. Note that virtual_mailbox_base is unconditionally
+ prepended to this path.
+
+virtual_minimum_uid
+
+ Specifies a minimum uid that will be accepted as a return from a
+ virtual_uid_maps lookup. Returned values less than this will be
+ rejected, and the message will be deferred.
+
+virtual_uid_maps
+
+ Recipients are looked up in this map to determine the UID to be
+ used when writing to the target mailbox.
+
+virtual_gid_maps
+
+ Recipients are looked up in this map to determine the GID to be
+ used when writing to the target mailbox.
+
+virtual_usedotlock
+
+ Use dot-locking when writing to mailboxes - defaults to off.
+
+[ - Exemple configuration - ]
+
+In main.cf file :
+--/---
+ virtual_mailbox_base = /var/mail/vhosts
+ virtual_mailbox_maps = dbm:/etc/postfix/vmailbox
+ virtual_minimum_uid = 100

+
+Don't forget to add in master.cf the entry for the agent, that should be

+
+--/---
+virtual unix - n n - - virtual
+--/---
+
+NOTES :
+-------
+
+1- Don't forget to add dbm:/etc/posfix/vmailbox into your
+local_recipent_maps in main.cf like :
+
+--/---
+local_recipient_maps = $alias_maps dbm:/etc/posfix/vmailbox unix:passwd.byname
+--/---
+
+2- If you use only the virtual localdelivery you can add the following line
+into main.cf
+
+--/---
+mailbox_transport = virtual
+--/---
+
+Otherwise you can use transport_maps :
+
+In main.cf file :
+
+--/---
+transport_maps=dbm:/etc/postfix/transport
+--/---
+
+In transport file :
+
+--/---

+VIRTUAL(8) VIRTUAL(8)
+
+
+<b>NAME</b>
+ virtual - Postfix virtual mail delivery
+
+<b>SYNOPSIS</b>
+ <b>virtual</b> [generic Postfix daemon options]
+
+<b>DESCRIPTION</b>
+ The <b>virtual</b> daemon processes delivery requests from the
+ Postfix queue manager to deliver mail to virtual local
+ recipients. Each delivery request specifies a queue file,
+ a sender address, a domain or host to deliver to, and one
+ or more recipients. This program expects to be run from
+ the <a href="master.8.html"><b>master</b>(8)</a> process manager.
+
+ This daemon is designed for ISP's offering virtual mail
+ hosting services. Originally based on the local delivery
+ agent, this agent locates user mailboxes via map lookups
+ of the full recipient address, rather than hard-coded unix
+ password file searches of the local part only.
+
+ The <b>virtual</b> daemon updates queue files and marks recipi-
+ ents as finished, or it informs the queue manager that
+ delivery should be tried again at a later time. Delivery
+ problem reports are sent to the <a href="bounce.8.html"><b>bounce</b>(8)</a> or <a href="defer.8.html"><b>defer</b>(8)</a> dae-
+ mon as appropriate.
+
+<b>MAILBOX</b> <b>DELIVERY</b>
+ The default per-user mailbox is a file in the UNIX mail
+ spool directory (<b>/var/mail/</b><i>user</i> or <b>/var/spool/mail/</b><i>user</i>);
+ the location can be specified with the <b>mail</b><i>_</i><b>spool</b><i>_</i><b>direc-</b>
+ <b>tory</b> configuration parameter.
+
+ In the case of UNIX-style mailbox delivery, the <b>local</b> dae-
+ mon prepends a "<b>From</b> <i>sender</i> <i>time_stamp</i>" envelope header to
+ each message, prepends a <b>Delivered-To:</b> header with the
+ envelope recipient address, prepends a <b>Return-Path:</b> header
+ with the envelope sender address, prepends a > character
+ to lines beginning with "<b>From</b> ", and appends an empty
+ line. The mailbox is locked for exclusive access while
+ delivery is in progress. In case of problems, an attempt
+ is made to truncate the mailbox to its original length.
+
+ In the case of <b>maildir</b> delivery, the local daemon prepends
+ a <b>Delivered-To:</b> header with the envelope recipient address
+ and prepends a <b>Return-Path:</b> header with the envelope
+ sender address.
+
+<b>DELIVERY</b> <b>RIGHTS</b>
+ Deliveries to mailboxes are made with the rights of the
+ receiving user on whose behalf the delivery is made.
+
+<b>STANDARDS</b>

+
+
+<b>DIAGNOSTICS</b>
+ Problems and transactions are logged to <b>syslogd</b>(8). Cor-
+ rupted message files are marked so that the queue manager
+ can move them to the <b>corrupt</b> queue afterwards.
+
+ Depending on the setting of the <b>notify</b><i>_</i><b>classes</b> parameter,

+ ble.
+
+<b>CONFIGURATION</b> <b>PARAMETERS</b>

+/* This daemon is designed for ISP's offering virtual mail hosting
+/* services. Originally based on the local delivery agent, this agent
+/* locates user mailboxes via map lookups of the full recipient
+/* address, rather than hard-coded unix password file searches of
+/* the local part only.
+/*
+/* The \fBvirtual\fR daemon processes delivery requests from the
+/* Postfix queue manager to deliver mail to virtual local recipients.
+/* Each delivery request specifies a queue file, a sender address,
+/* a domain or host to deliver to, and one or more recipients.
+/* This program expects to be run from the \fBmaster\fR(8) process
+/* manager.
+/*
+/* The \fBvirtual\fR daemon updates queue files and marks recipients
+/* as finished, or it informs the queue manager that delivery should
+/* be tried again at a later time. Delivery problem reports are sent
+/* to the \fBbounce\fR(8) or \fBdefer\fR(8) daemon as appropriate.
+/* MAILBOX DELIVERY
+/* .ad
+/* .fi
+/* The \fBvirtual\fR delivery agent can deliver to UNIX-style mailbox
+/* file or to qmail-style maildir files. The pathname and delivery
+/* mailbox style are controlled by the $\fBvirtual_mailbox_base\fR
+/* and \fB$virtual_mailbox_maps\fR parameters (see below).
+/*
+/* In the case of UNIX-style mailbox delivery,
+/* the \fBlocal\fR daemon prepends a "\fBFrom \fIsender time_stamp\fR"
+/* envelope header to each message, prepends a \fBDelivered-To:\fR header
+/* with the envelope recipient address, prepends a \fBReturn-Path:\fR
+/* header with the envelope sender address, prepends a \fB>\fR character
+/* to lines beginning with "\fBFrom \fR", and appends an empty line.
+/* The mailbox is locked for exclusive access while delivery is in
+/* progress. In case of problems, an attempt is made to truncate the
+/* mailbox to its original length.
+/*
+/* In the case of \fBmaildir\fR delivery, the local daemon prepends
+/* a \fBDelivered-To:\fR header with the envelope recipient address
+/* and prepends a \fBReturn-Path:\fR header with the envelope sender
+/* address.
+/* DELIVERY RIGHTS
+/* .ad
+/* .fi
+/* Deliveries to mailboxes are made with the UID and GID that are listed
+/* for the recipient in the tables listed in the \fB$virtual_uid_maps\fR
+/* and \fB$virtual_gid_maps\fR, respectively.
+/*
+/* The \fBvirtual_minimum_uid\fR parameter specifies a lower bound on
+/* UID values that may be specified in \fB$virtual_uid_maps\fR. Mail
+/* will not be delivered when an invalid UID is found.
+/* STANDARDS
+/* RFC 822 (ARPA Internet Text Messages)
+/* DIAGNOSTICS
+/* Problems and transactions are logged to \fBsyslogd\fR(8).
+/* Corrupted message files are marked so that the queue
+/* manager can move them to the \fBcorrupt\fR queue afterwards.
+/*
+/* Depending on the setting of the \fBnotify_classes\fR parameter,
+/* the postmaster is notified of bounces and of other trouble.
+/* CONFIGURATION PARAMETERS
+/* .ad
+/* .fi
+/* The following \fBmain.cf\fR parameters are especially relevant to
+/* this program. See the Postfix \fBmain.cf\fR file for syntax details
+/* and for default values. Use the \fBpostfix reload\fR command after
+/* a configuration change.
+/* .SH Mailbox delivery
+/* .ad
+/* .fi
+/* .IP \fBvirtual_mailbox_base\fR
+/* Specifies a path that is prepended to all mailbox or maildir paths.
+/* This is a safety measure to ensure that an out of control map in
+/* \fBvirtual_mailbox_maps\fR doesn't litter the filesystem with mailboxes.
+/* While it could be set to "/", this setting isn't recommended.
+/* .IP \fBvirtual_mailbox_maps\fR
+/* Recipients are looked up in this map to determine the path to
+/* their mailbox or maildir. If the returned path ends in a slash
+/* ("/"), maildir-style delivery is carried out, otherwise the
+/* path is assumed to specify a mailbox file.
+/*
+/* Note that \fBvirtual_mailbox_base\fR is unconditionally prepended
+/* to this path.
+/* .IP \fBvirtual_minimum_uid\fR
+/* Specifies a minimum uid that will be accepted as a return from
+/* a \fBvirtual_uid_maps\fR lookup. Returned values less than this
+/* will be rejected, and the message will be deferred.
+/* .IP \fBvirtual_uid_maps\fR
+/* Recipients are looked up in this map to determine the UID to be
+/* used when writing to the target mailbox.
+/* .IP \fBvirtual_gid_maps\fR
+/* Recipients are looked up in this map to determine the GID to be
+/* used when writing to the target mailbox.
+/* .SH "Locking controls"
+/* .ad
+/* .fi
+/* .IP \fBmailbox_delivery_lock\fR
+/* How to lock UNIX-style mailboxes: one or more of \fBflock\fR,
+/* \fBfcntl\fR or \fBdotlock\fR.
+/* .IP \fBdeliver_lock_attempts\fR
+/* Limit the number of attempts to acquire an exclusive lock
+/* on a mailbox file.
+/* .IP \fBdeliver_lock_delay\fR
+/* Time in seconds between successive attempts to acquire
+/* an exclusive lock on a mailbox file.
+/* .IP \fBstale_lock_time\fR
+/* Limit the time after which a stale lockfile is removed.
+/* .SH "Resource controls"
+/* .ad
+/* .fi
+/* .IP \fBvirtual_destination_concurrency_limit\fR
+/* Limit the number of parallel deliveries to the same domain.
+/* The default limit is taken from the
+/* \fBdefault_destination_concurrency_limit\fR parameter.
+/* .IP \fBvirtual_destination_recipient_limit\fR
+/* Limit the number of recipients per message delivery.
+/* The default limit is taken from the
+/* \fBdefault_destination_recipient_limit\fR parameter.
+/* HISTORY
+/* .ad
+/* .fi
+/* This agent was originally based on the local delivery
+/* agent. Modifications mainly consisted of removing code that wasn't
+/* applicable or wasn't safe in this context (aliases, .forwards,
+/* program aliases).
+/*
+/* The \fBDelivered-To:\fR header appears in the \fBqmail\fR system
+/* by Daniel Bernstein.
+/*
+/* The \fImaildir\fR structure appears in the \fBqmail\fR system
+/* by Daniel Bernstein.
