From: JunkYardMail1 on 3 Jul 2010 22:50 Oh and here is another thought. Go back to the very first failure occurrence for draxlerinsurance.com and see what the cause of that very first rejection was. -------------------------------------------------- From: <JunkYardMail1(a)Verizon.net> Sent: Saturday, July 03, 2010 7:42 PM To: "Asai" <asai(a)globalchangemusic.org>; <postfix-users(a)postfix.org> Subject: Re: Connection Refused on Port 25 > > Have you verified your MTA's are not on a Black/Block list?

You could do a DNS lookup and find the technical contact for that domain, and write to that person about the issue. You could also contact any legitimate users and ask if they can forward a message to the IT or technical support contact for their mail server. If the domain is for a company, check their web page to see if any support contact may be listed, and try that. > > This won't be a simple process, and once you actually reach someone, and convincing them they they have an issue can sometimes be an uphill battle.
