Hello,
I am debugging a faulty operation of dkim-filter and have been asked
whether I can "capture/quarantine the message(s) which are in progress
at the time of the crash".
Is this possible with postifx? I looked at the main.cf parameters but
have not seen anything relating to capturing messages.
Many thanks!

access maps, header_checks, and body_checks have a HOLD action
which will keep mail in the "hold" queue rather than
delivering it.
The always_bcc, recipient_bcc_maps, and sender_bcc_maps
parameters send a copy of a message to a specified recipient.
Development snapshots also have a BCC action for access maps.
For an extreme case, you can use dont_remove, which moves each
queue file to the "saved" queue rather than deleting it when
postfix is done processing it.
Maybe one of those will do what you need.

Although if the mail is deferred I'm not sure any of these
will help. You might need to use tcpdump to record the
network traffic as it arrives.
