General email troubleshooting [2/2]

If you get a telnet output similar to this one:

C:\Documents and Settings>telnet smtp.yourdomain.com 25
Trying 123.123.123.123...
Connected to osmtp.yourdomain.com (123.123.123.123).
Escape character is '^]'.
220 smtp.yourdomain.com ESMTP
You should have no problems with the mail server. If it is stuck on Trying 123.123.123.123... please contact you service provider to see if the port is not blocked on the server.


It is similar to check connectivity with your incoming server command is just telnet mail.yourdomain.com 110. Also note that the port numbers may vary depending on your hosting provider. For example many companies use for outgoing server instead of 25 , port 587.
