Re: [qmailtoaster] Questions about control/taps
I'm guessing somewhere near the tail end of the delivery process, like qmail-local or maildrop. I don't know where/how maildrop hooks in, but that's where I'd look. Maybe 'tee' off a copy to a backup directory under the user's directory.

I use amanda (http://www.amanda.org/) for network backups of whole racks and works like a charm, but you can allways use a priopietary one like Veritas BackupExec or something like that.

RE: [qmailtoaster] Questions about control/taps
From what I can tell, taps is executed before the .qmail and/or .qmail-default files are executed and after clam spamassassin. Also, if you use a line such as: .*:[EMAIL PROTECTED] To tap an entire domain, it will create an endless loop, even if the messages are not sent to [EMAIL PROTECTED] What I've done is set up a faux domain to handle the taps, with a line such as: [EMAIL PROTECTED]:[EMAIL PROTECTED] While logs.my.domain.com doesn't exist, my.domain.com does. You would need to set one of these up for each individual domain, however they could all forward to the same account. Just make sure not to tap the logging domain, or you will get into another endless loop... Hope this makes sense. If anyone sees anything incorrect, please correct me. :) -Jason -Original Message- From: Eric Shubes [mailto:[EMAIL PROTECTED] Sent: Monday, November 13, 2006 11:02 AM To: qmailtoaster-list@qmailtoaster.com Subject: Re: [qmailtoaster] Questions about control/taps I'm guessing somewhere near the tail end of the delivery process, like qmail-local or maildrop.
