I had civimail finally working, and a lovely thing it was. 

Then all of the mail from the CiviCRM stopped working.  After checking settings, making a few changes, and learning all about 550 Sender Verify Failed, I have sending mail to contacts working again, as well as the registration confirmation email working.  CiviMail is still not working.  In comparing entries on the exim_mainlog on my server, it appears that the email address that is failing to verify is the REPLY TO email address generated automatically by CiviMail so that bounces & such are processed.  The log looks like this:

2009-11-04 22:39:27 H=server.mydomain.org (localhost) [xx.xxx.xx.xx] F=<bounce.1.53.4507.a186f6de8fcbd1093626f289c16a8a26dfc41a89-emailuser=recipientdomain.com@mydomain.org> rejected RCPT <emailuser@recipientdomain.com>: Sender verify failed

If anyone can help me figure out why this is happening, I would really appreciate it.

Alternatively, you can turn off SMTP level bounce tracking, which will make CiviCRM use a single MAIL FROM address. (But it’s a bad idea to ignore SMTP-level bounces and then try to resend to these addresses again and again.)
