How to figure out the SMTP server host?

You can use the dig/host command to look up the MX records to see which mail server is handling mails for this domain.

On Linux you can do it as following for example: 

$ host google.com
google.com has address 74.125.127.100
google.com has address 74.125.67.100
google.com has address 74.125.45.100
google.com mail is handled by 10 google.com.s9a2.psmtp.com.
google.com mail is handled by 10 smtp2.google.com.
google.com mail is handled by 10 google.com.s9a1.psmtp.com.
google.com mail is handled by 100 google.com.s9b2.psmtp.com.
google.com mail is handled by 10 smtp1.google.com.
google.com mail is handled by 100 google.com.s9b1.psmtp.com.

(as you can see, google has quite a lot of mail servers)

If you are working with windows, you might use nslookup (?) or try some web tool (e.g. that one) to display the same information.

Although that will only tell you the mail server for that domain. All other settings which are required can't be gathered that way. You might have to ask the provider.


generally smtp servers name are smtp.yourdomain.com or mail.yourdomain.com open command prompt try to run following two commands

  1. >ping smtp.yourdomain.com
  2. >ping mail.yourdomain.com

you will most probably get response from any one from the above two commands.and that will be your smtp server

If this doesn't work open your cpanel --> go to your mailing accounts -- > click on configure mail account -- > there somewhere in the page you will get the information about your smtp server

it will be written like this way may be :

Incoming Server:    mail.yourdomain.com
IMAP Port: ---
POP3 Port: ---
Outgoing Server:    mail.yourdomain.com
SMTP Port: ---

You could send yourself an email an look in the email header (In Outlook: Open the mail, View->Options, there is 'Internet headers)


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.
