Hi Everyone For some reason my Imail server can't send email to one server however I can do it from my personal email account. At this time they are saying that their server is working perfectly because they can send and receive email.   I need to resolve this problem somehow. Does anyone know where/how to begin to troubleshoot this problem?   I have a virus scanner listening on port 25 forwarding it to Imail.     here is a sample from the log.   12:19 10:26 SMTP-(000002BD) processing C:\IMAIL\spool\Qa85726e.SMD 12:19 10:26 SMTP-(000002BD) Trying careersite.com (0) 12:19 10:26 SMTP-(000002BD) Connect careersite.com [192.168.1.63:25] (1) 12:19 10:26 SMTP-(000002BD) 421 SMTP service not available, closing transmission channel 12:19 10:26 SMTP-(000002BD) SMTP_DELIV_FAILED 12:19 10:26 SMTP-(000002BD) >QUIT 12:19 10:26 SMTP-(000002BD) 12:19 10:26 SMTP-(000002BD) requeuing C:\IMAIL\spool\Qa85726e.SMP R0 T1 12:19 10:26 SMTP-(000002BD) finished C:\IMAIL\spool\Qa85726e.SMP status=3   Thank you Rafal Karpinski Howard & Edwards Worldwide IT Dept. 818-654-2600
