Have you checked your IP's against the blacklists?  Also, have you tried re-installing?  You can test your DNS by running nslookup (from the server).   cmd c:\>NSLOOKUP your dns server gets named... > set type=all > some_domain.com (where some_domain.com is one of the domains you are having trouble sending to) You should get something like... > set type=all > somedomain.com Server:  you.dns_server.com Address:  x.x.x.x   Non-authoritative answer: somedomain.com  nameserver = ns1.ultsearch.com somedomain.com  nameserver = ns2.ultsearch.com   ns1.ultsearch.com       internet address = 213.130.63.232 ns2.ultsearch.com       internet address = 212.100.230.160 >   ---------------------------   if you get a valid address, DNS is not your problem.   HTH, ~Vaughn ----- Original Message ----- From: Jeffrey Owen To: [EMAIL PROTECTED] Sent: Sunday, August 03, 2003 1:37 AM Subject: [IMail Forum] SMTP Rejections I have recently made some changes to my IMail Server and I am now experiencing problems delivering email and I am hoping that someone has seen this problem before.   I am running IMail 8.01   Before making any changes to the server all Email Domains had their own separate IP Address.  Now with the changes I have 3 IP addresses attached to 3 domains.  These 3 domains control 3 different SPAM settings.  All other domains are assigned to virtual accounts under the 3 IPs.  Once having done this I have began to get the following error messages when sending email to specific domains.  We can receive email from these domains, but not send email out.  I can go to another email system and send without any problems.  A problem with my DNS maybe?  Any suggestions would be greatly appreciated.   08:02 01:22 SMTP-(10380049) 421 SMTP service not available, closing transmission channel 08:02 01:22 SMTP-(10380049) SMTP_DELIV_FAILED 08:02 01:22 SMTP-(10380049) >QUIT 08:02 01:22 SMTP-(10380049)   Thanks,   Jeffrey Owen Automated Results Applying Today's Technology to Generate Tomorrow's Results Office: 828.862.6667 Fax: 828.877.6068 Cell Phone/Voice Mail: 828.243.5931 E-Mail:   [EMAIL PROTECTED] Web Site: http://www.AutomatedResults.Com
