The transport failed to connect to the server.

Post by erick.abreu.gomes » Thu May 09, 2019 5:42 pm

Hello everyone, I have a problem with my email server.

When trying to send an email through a script through mail.domain.com, I get the error "The transport failed to connect to the server."

but if you change mail.domain.com by IP, send normally.

Anyone have any tips?

Hi,

Does the mail.domain.com resolve to the MailEnable servers IP address? Are you able to telnet to mail.domain.com on port 25 and receive a MailEnable SMTP response?

Hi Ian,

thanks for answering.

returns the following:

Code: Select all

telnet mail.domain.com 25
220 mail.domain.com ESMTP MailEnable Service, Version: 10.12-- ready at 05/15/19 21:29:10

telnet mail.domain.com 587
220 mail.domain.com ESMTP MailEnable Service, Version: 10.12-- ready at 05/15/19 21:31:20

telnet 200.1.2.3 25
220 mail.domain.com ESMTP MailEnable Service, Version: 10.12-- ready at 05/15/19 21:33:50

telnet 200.1.2.3 587
220 mail.domain.com ESMTP MailEnable Service, Version: 10.12-- ready at 05/15/19 21:35:01
is correct?

Hi,

Yes that is correct. You will need to try your tests again and then inspect the MailEnable SMTP activity and debug log files to troubleshoot further.
