Reproducible: Always Steps to Reproduce: 1. send mail message to an account you can read 2. observe Received: headers for detailed information 3. notice the last "Received: from xxxx" where xxxx always is the sender's address domain name Actual Results: You see confusing sequences when the sender uses some company mailserver, an extra server that relays mail to Internet, and uses their domain name when sending messages to the world. E.g.: Received: from company.com by .... Received: from mail.company.com by company.com ... Received: from company.com by mail.company.com .... ^^^^^^^^^^^^^^^^ this string is inserted when mail is sent from user@company.com using mozilla. better would be if it read something like "from pc123.company.com" (the hostname of the sending machine) Expected Results: The EHLO string should be configurable, probably in the advanced tab of the SMTP server configuration dialog. Best would be if there are some pre-selectable options: 1. the domain name part of the mail address (current situation) 2. the hostname of this machine 3. a user-configurable name (text field)

The bug has been open for so long that the world (and Mozilla) has changed from SMTP to ESMTP in the meantime, so I could not find it by searching for EHLO... sorry. What would it take to get things moving again?
