Comment 27 for bug 148362

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.3) Gecko/20030312

My behaviour is:
I created a new SMTP server record and assign it to one of mail account. Now I
have two SMTP servers, default and custom, which one I want to use for several
mail accounts (with different corresponding mail account settings!). When I send
newly created message from these accounts, how can I be sure that desired (but
not default) SMTP server is in use? Mozilla didn't ask me for a password, just
silently sent a message. But when I again use Advanced button to make myself
sure that there is a server I need there, it started to ask me for a password,
but was continiously failing to send it due to "invalid login/password" or
something similar.

I think it's some kind of security issue, for example I wish to be completely
sure that certain e-mails go through _this given_ server only and not through
anyone else. So it's not "minor" level, it should be higher.
