The SMTP connection appears to send the mail, but an error appears indicating
that the SMTP connection has failed.  Attempts to re-send the message may or may
not generate the same warnings.  In fact, the SMTP connection has sent the
message, as many times as you've tried, but the mail message is not saved into
the remote SENT folder.  All folders are IMAP.  Eventually, after several
retries, the SEND operations appears to work and the sent message is saved in my
SENT folder.  I then get many emails from colleages nagging me for sending them
several copies of an email.

Reproducible: Always

Steps to Reproduce:
1.  Compose a new, or reply to, an email message.
2.  Type in your message, address the message, etc.
3.  Hit "Send".
4.  Wait for errors and follow the "retry" instructions, sending many emails and
annoying colleages.  Eventually it will work.
Actual Results:  
Read "Details" section.

Expected Results:  
Sent the email and saved a copy it in my SENT folder ... on the first attempt!!!

Version 1.2.1 (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1)
Gecko/20021130) works well.  The new version 1.3 that I downloaded on 2002-03-13
does not work.

Whoops. My comment #1 above was an accident I made when I marked another bug
wrongfully as a duplicate of this one.

Sample of what a testcase SMTP session would look like

This is easy to duplicate..

if, after the mail is sent, the ISP closes the session instead of waiting for
Mozilla to close it, Mozilla throws a tantrum, but it has already said that the
mail was sent. it does not close the mail composer window and it does not put
it in the Sent folder.

This is an example of an SMTP server session for which Mozilla would have 
this problem.

This has been seen by me on macOS-X and FreeBSD in addition to PC
I see it on Mozilla 1.4 and 1.6. so should be OS= ALL

Comment 5

15 years ago hangs up on me after the data section now.  They just 
started doing it.  I get this error in mozilla 1.4 and 1.6.  SBC refuses to fix 
the smtp issue in sendmail.  Does anyone know if this happens in NS4/6/7?
