An error message pops up, as reproduced here -- http://leonardo.bryant.edu/pub/Moz/Moz_SMTP_030926_1840_.gif where 12.91.42.4 is my dhcp address Reproducible: Always Steps to Reproduce: 1. Attempt to send a very simple email 2. 3. Actual Results: Messenger displays the error message reproduced here -- http://leonardo.bryant.edu/pub/Moz/Moz_SMTP_030926_1840_.gif Expected Results: Sent the email ! Mozilla is on a machine on a local network 10.x connected to the internet by a NAT on the machine with the modem (to my ISP, ATT) This setup has been working for five years, flawlessly........ with all versions of Netscape Communicator and Mozilla...... including the 20030911 version

What server is listed in the Account Manager for the SMTP servers?

so it is the mail server responding that it is unhappy with your IP address... very interesting.

Q: What server is listed in the Account Manager for the SMTP servers? A: 192.124.153.44 (Which I have used for the last eight years)

Q: so it is the mail server responding that it is unhappy with your IP address... very interesting. A: I am not able to decipher the error message. I posted it at http://leonardo.bryant.edu/pub/Moz/Moz_SMTP_030926_1840_.gif I am not sure that it is the smtp server that I am using: 192.124.153.44 that is responding with this error message.......

Can you please try and attach a protocol log for SMTP to this bug (as plain text)? Instructions for generating one can be found at http://www.mozilla.org/quality/mailnews/mail-troubleshoot.html#imap (please substitute SMTP where it says IMAP). Thanks!

Reply to: #5 From Stephen Donner 2003-09-26 22:41 ------- The SMTP log I got is placed at -- http://leonardo.bryant.edu/pub/Moz/Moz_SMTP_030927_0231_.log The 12.91.42.37 is my current dhcp address dynamically allocated to me by my ISP (ATT) The 192.124.153.44 is the smtp server I have been using for eight years and which is working flawlessly with Mozilla nightly build 20030911 The error message is placed at -- http://leonardo.bryant.edu/pub/Moz/Moz_SMTP_030927_0225_.gif In the log, the error message ""The domain you are trying to send mail to does not exist"" is totally incorrect because the domain leonardo.bryant.edu (192.124.153.44) is alive and has been alive for eight years....

Michel, what happens if you're sending mail to an other recipient? Hm, he server answers with "220 sitefinder.verisign.com VeriSign mail rejector (Postfix)". Mail rejector? Interesting. Even more interesting is what I get if I telnet 192.124.153.44: "220 leonardo -- Server ESMTP (iPlanet Messaging Server 5.1 (built May 7 2001))" That looks better. You still have the same problem? Maybe it was a temporary redirect.

This one looks to me like a dupe to bug 219449. Could you please check if your problem still occurs when using a build with the fix from bug 219376 (which is the bug, 219449 was duped against)?

Reply to #8 From Christian Eyrich I can now send and receive emails from 192.124.153.44 without any problem using build 20031004 Thanks ! Michel
