From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.1a) Gecko/20020610 BuildID: 2002061204 Outgoing mails are sent via the smtp server which is assigned to the first mail account, regardless what is default or which from account you've chosen. But only if the mail will be saved in "Unsent Messages" for later and then sent by "Send Unsent Messages". If you type the mail and send it immediately, everything's fine. Reproducible: Always Steps to Reproduce: 1. Configure two mail accounts 2. Assign the first account smtp server a and the second account smtp server b 3. Write a mail using sender of second account and click send 4. Write a mail using sender of second account, klick send later, then click send unsend messages. 5. Compare path of both messages (you have to send the messages to yourself of course) or watch what server will be connected via a personal firewall a.s.o Actual Results: Different servers used Expected Results: Same servers should be used Can reproduce this with 2002061014 on Linux and 202061204 on Win95 (both 1.1a). Maybe you can't follow my steps and the cause it's the main reason I noticed this bug. If your mail provider checks if the from domain matches his domain resp. if the from-user is known to him. So mail provider of the first account with server a doesn't know the from mail-address when using account b.
