Hi,Running Postfix under Jessie. At some time in the past I managed to increase the logging verbosity to track down a problem, which I've solved.I now have a vast amount of data in mail.log, which is obscuring useful messages. I thought it was simply a matter of adding or removing "-v" to the service configuration stanzas in /etc/postfix/master.cf, but on reviewing that file, I see no instances of -v, e.g,smtp inet n - n - - smtpdThe logged data even includes users passwords in clear, as well as 20-odd lines for each email received (sample attached).Can anyone please suggest any other places to look to reset the default log level
This doesn't look like verbose logging to me. I think the problem is just that you have a complex chain of processes for the message to pass through. bendel.d.o connects to you, the message is passed by the greylisting daemon postgrey and is accepted by your system. The message is then forwarded to amavis. At that point postfix is finished with that message. Amavis now checks the message and pronounces it clean. Amavis now connects back to postfix and passes the approved message back in. Postfix delivers the message to the SECOND delivery agent (virtual), which delivers it to your maildir.
If you like, you could look at making amavis into what postfix calls a "Before Queue Filter" (and which everyone else calls a milter). There is an amavisd-milter package which will help with that. Basically, instead of accepting the message and THEN checking it for viruses, the message is passed through amavis DURING the smtp session. Postfix will only accept the message if amavis approves it, otherwise the remote host will be told that the message is rejected. This is a nicer solution all around, but it does mean that SMTP sessions will take longer. That is, you might not be able to accept as much mail as you would be able to using amavisd's batch mode.
