The following recipient(s) could not be reached:
user@domain.com on 03/08/2007 12:26
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<craftynotions.com #5.5.0 smtp;550-e1636700.demon.co
.uk (craftynotions.com) [83.105.91.89] is currently not>
Stopped working about a week ago. No idea what changed. Incoming email ok. Can send using Outlook Express to mail.craftynotions.com (same mail server) so domain host seems ok.
I've rummaged around on EE re similar messages and looked at some solutions, but no luck. ESM Recipient Policies show @craftynotions.com, not .local.
The isp say it is not a reverse dns problem. FQDN is set to our domain, craftynotions.com. They are sure it is a exchange problem at our end.
Help much appreciated!
