I'm struggling to get mail through to Comcast on our new-to-us IPs from Linode. We are a sending less than a dozen emails and getting throttled:
May 23 14:14:46 atl3i postfix/smtp[5795]: 53C0A915D: to=< redac...@comcast.net>, relay=mx1c1.comcast.net[96.102.18.148]:25, delay=460, delays=458/1.7/0.71/0.17, dsn=4.1.0, status=deferred (host mx1c1.comcast.net[96.102.18.148] said: 421 4.1.0 170.187.200.41 Throttled - try again later. Please see http://postmaster.comcast.net/smtp-error-codes.php#RL000003 (in reply to MAIL FROM command)) des.php#RL000003 (in reply to MAIL FROM command)) We send from bivio.com, zoescore.com, and sensorimotor.org from 170.187.200.41. We just got off the Vade Secure list, and I thought that would be sufficient. Could someone from Comcast help out? Thanks, Rob
