Nick: Leaving a domain and IP fallow for such a long time will end up looking like my garden did this year when I did the same thing -- overrun with weeds. Sending a blanket e-mail to NANOG is not going to get the attention of those who manage the e-mail flow (unless you domain belonged to a Fortune 100). Just like I should have with my garden, rather than replant among the weed seeds and spend 99% of my time pulling weeds, I would recommend sowing a new field by moving your outbound e-mail server(s) to some fresh address space (different /24 to be sure, ideally another section of SWIPed space) and start monitoring your outgoing servers logs. You'll need to work with each MTA that blocks your e-mail and ask them to delist you from whatever block (domain or domain reputation) that they have. At the same time, systematically go to every RBL that tracks by domain name and check the status of your domain and request delisting as necessary.

For an un-known amount of time (A month or more?) mail.tacid.org has been an open-relay, and sending out large amounts of spam. This should now be fixed. If anyone is having issues with this domain still, please contact me off list. Thank you, Nick
