Subject: imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs.
X-Git-Tag: 2.2.26~270
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e90a0ed00032388ffe15b10c2ebf115355d553d5;p=thirdparty%2Fdovecot%2Fcore.git

imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs.

This at least partially replaces the "rawlog" post-login binary. For now
the "rawlog" binary supports some parameters, which aren't configurable
for rawlog_dir.
