I run a cPanel shared host and run a number of mailman2 mailing lists from different domains. Last week my IP address got changed from 66.35.84.90 to 172.110.191.18, now on all the mailing lists addresses to AOL, Yahoo, and Verizon (and any other ones they service) are getting a soft bounce:
421 4.7.0 [TSS04] Messages from 172.110.191.18 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; Can my new IP address be allowed to send email to people who signed up? My old IP address didn't have this problem. Thanks, Ken Robinson
