Hello everybody,
I use pipe to start my own script when an email to a certain address
is received. The script will do it's own logging and I want to be able
to correlate that logging with the Postifx logs. The queue id that is
used in the Postifix logs seems ideal for that. I think it's called
queue id in Postfix terminology, but to be clear, I'm referring to
21D5D497FE in the example below:
Nov 11 12:29:39 WCEA006 postfix/smtpd[28104]: 21D5D497FE: client=....
That is the Queue-ID, true.
However, since it's used internally by postfix, once a message is
delivered it is no longer of use.
It is not communicated to external commands.So my question is: is there
any way I can have pipe pass the queue id
into my script? I couldn't find anything in the man page. If not, is
there another way in which I can make an easy correlation to the
Postifx logs? I use Postfix 2.7.0.
Postfix logs delivery to a pipe(8) command by sepcifically naming the
service in master.cf that was used.
This provides one part - you can screen the postfix log for that transport.
I would just log a (timestamp, sender, recipient, nexthop) tuple; this
should provide enough specifics to correlate with the postfix logs.
You can also log that same tuple for each message (on a single line) by
adding
smtpd_client_restrictions = check_client_access static:WARN
to your main.cf.
Of course, the extra log comes at a marginal price in performance - I
don't know how much exactly but it can't be big.
Thank you,
Catalin Iacob
