	    Bugfix (defect introduced: date 19991116): when appending a setting to a
		main.cf or master.cf file that did not end in a newline character, the
		"postconf -e" command did not add an extra newline character before
		appending the new setting, causing information to become garbled. Fix
		by Michael Tokarev.
	    Bugfix (defect introduced: Postfix 2.3, date 20051222): the Dovecot auth
		client did not attempt to create a new connection after an I/O error on
		an existing connection. Reported by Oleksandr Kozmenko.
	    Improved and corrected error messages when converting (host or service)
		information to (symbolic text, numerical text, or binary) form.
	    Documentation: updated link to Dovecot documentation.
