How to figure out the SMTP server host? [closed]

by

this really is a question for Serverfault.

Windows:

  1. Open up a command prompt (CMD.exe)
  2. Type nslookup and hit enter
  3. Type set type=MX and hit enter
  4. Type the domain name and hit enter, for example: google.com
  5. The results will be a list of host names that are set up for SMTP

Linux:

  1. Open a command prompt
  2. Type dig domain.name MX and hit enter where domain.name is the domain you are trying to find out the smtp server for.

If you do not get any answers back from your dns server, there is a good chance that there isn’t any SMTP Servers set up for that domain. If this is the case, do like other’s have suggested and call the hosting companies tech support.
