My problem... Postfix is not sending to certain hosts. most mail is delivered fine, but some just sit in the queue I know the mailbox is live and I can send to it from other email account. I have checked the blacklists and all is fine there. Not sure what to do next??? Here's an example from the log. Code: Nov 19 23:36:21 cgslice01 postfix/smtp[24593]: 058B9A01AD: to=<[email protected]>, relay=none, delay=1214, delays=1184/0.02/30/0, dsn=4.4.1, status=deferred (connect to smtpin.ntlworld.com[81.103.221.10]:25: Connection timed out) I'd really appreciate some help on this one. Thanks
Hey Falko, Great tut's btw. I checked the blacklists and all come back clean with the exception of about 5 which have an either... TIMEOUT Return codes were: ERROR, Reponse code=2 or... TIMEOUT When I follow the link to the sites the server is unavailable so I am guessing that indicates a problem their end rather than my server being blacklisted. Have you any other ideas? I have posted the ouitput of postconf -n below.

There are quite a few hosts that are refusing to accept mail. Not just the one I listed. Some well known providers like ntlworld.com and tesco.net included.
Do you have proper SPF and reverse records for your email domains? I'd ask them if they use an internal blacklist and if you are on it.
