Re: How Can I Wipe Out Emails From Specific Sender

The remote senders email is always the same and somehow gets bounced for days in between my postfix server and my exchange bridgehead. What can I do to just delete it once and for all? I've tried looking for it on the queue, but it gets past that too quickly. Thanks, .vp You're too kind to your end-users. That's what client-side filters are for :-) Seriously, I wouldn't think that was worth solving with postfix or any MTA. -- If this was a real .signature it would be more interesting.

That result means your command shell doesn't know where postconf is. Try: 'locate postconf' to find it. Then edit your PATH appropriately. If you have a queue of mail you want to preserve, it might make sense to archive that and arrange for your hosting provider to hold on to it. If you are moving to a reprovisioned system, they could put it there. I don't know if putting it in place and starting up postfix would cause it all to be (re) sent or not. -- If this was a real .signature it would be more interesting

How did I get this [Sender address rejected: User unknown in virtual alias table] and how do I get rid of it?
Small domain, just a home network with a postfix server to keep the baddies out. But for some reason, outbound mail is failing for one user and I can't quite make out why.

This is likely why the client disconnected; your server was speaking SSL and the client was speaking normal SMTP. It looked like garbage to the client. Wrappermode should only be used on a dedicated port, typically 465 smtps. Hmm, that's been here forever, but I guess it was obsoleted by the recent authentication changes. Well, it looks like I am seeing some deliveries being logged, so maybe it's fixed. Any idea if I should care about this?
