1 What do the imail sever logs say? 2 Are you telneting directly form the MX servers to imail during your test? 3 Has it ever worked before or is this a new install?
Assuming Imail's relay setting are correct and also that your MX's know where your imail server is, this specific thing can occur when Imail's smtp can't keep up with the load from the two MX's. You may either be disk or processor bound. The symptom is sporadic port 25 connectivity. You could try slowing your MXs down a bit perhaps. -----Original Message----- From: David Clausen [mailto:[EMAIL PROTECTED] Sent: Friday, August 22, 2003 3:28 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] Connection refused errors Because of the new virus, I have 2 Mail Exchange Postfix servers sitting in front of my v7.15 IMail server collecting about 100k email/day. The MX servers are receiving repeated "Connection refused" errors when trying to forward queued email to Imail periodically during the day. However, I can telnet manually to port 25 without any problems just after receiving the error. Aug 22 18:19:28 mx2 postfix/nqmgr[57580]: B5F2911D98: to=<[EMAIL PROTECTED]>, relay=none, delay=0, status=deferred (connect to mail.domain.com[xx.xxx.xx.xx]: Connection refused) ^Z Suspended mx2# telnet mail.domain.com 25 Trying xx.xxx.xx.xx... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com (IMail 7.15 230-14) NT-ESMTP Server X1 And then mail will just sit there and queue on the MX servers despite me being able to connect via telnet. I've tried stopping SMTP Service and restarting, but no help. I will also get "server dropped connection without sending the initial greeting" errors sporadically. These machines are sitting next to each other in our Rack, and I am aware of no network issues between them. I'm fresh out of ideas. Thoughts?
