How to Check SMTP server of Recieved Emails

Question

I am using Interspire email marketer to send emails.

And I am using Mail Server Details to use my own SMTP server. For example mail.mymailserver.com in order to send the emails while my original server is something like www.myserver.com.

All I need is to check if mails are being sent from mail.mymailserver.com but in the headers of the emails I can see is ip and mail server of mail.myserver.com.

Is there any way I check this please?

Answer 1

Normally the receiving mail server will add a Received: header with IP and/or address of sending mail server. Be sure to send your test mail to some third party (that is, not to yourself at myserver.com).
