E-mail - SMTP communication problems with other servers
Posted on 2008-10-21
Lately, I have noticed problems with e-mailing external customers. It doesn't happen to every external e-mail account, just a select few which is odd I thought. The problem is that we attempt to send an e-mail, and almost immediately it comes back with
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
mymailserver.corp.newstandard.com #5.5.0 smtp;554 Transaction Failed Spam Message not queued
It's almost like it hits my Exchange box, and comes back with that immediately. Other times, when a message has failed and at least went out to the recipient e-mail server there is a bit of a delay until we receive an undeliverable message. I did a little bit of digger deeping, and found that my name server and MX record is still being hosted by an old ISP while the IP address actually belongs to another provider. I'm thinking this could be the problem? It's been this way for years though, never had problems like this before. IF this is the problem, do I just call my old ISP who is hosting my MX record and move it to my new ISP? Also, change my registrar and move the name servers to my new ISP as well? If i'm way off here, let me know! That's why I'm asking the questions here before I just do it :)
