We have seen this problem as well.  It seems to occur on Windows NT 4.0 machines
and some Windows 2000 machines.  In our cases, the e-mail actually gets sent,
BUT, the error message still comes up:
"Sending of message failed.
   The message could not be sent becuase connecting to the SMTP server < server
> failed.  The server may be available or is refusing SMTP connections.  Please
verify that your SMTP server setting is correct and try again, or else contact
your systems administrator"

We also use encrypted, authenticated SMTP connections and our mail server is a
Sun One IMS 5.2 server.  Almost all of our Netscape 7.1/Mozilla 1.4
installations work, except the two or three that "don't...they send but the
error message comes up"

I have experienced something similar.  After spending a signifcant amount of 
time wokring with my ISP/web host.  I cant connect to the smtp server in either 
Mozilla 1.4, 1.5, or thunderbird .3RC2.

I can successfully connect using Outlook Express and Outlook.

I am running a Windows 2000 box with SP5.

See Here:

It is no longer intermittent, it happens consistently every time
mail is sent.
Check all SMTP server settings through Edit/Mail&News Account Settings/Outgoing
Server(SMTP)/Advanced button/Edit button.
Is it defined as you expected?
Is it same as you defined?
Are there any character string of or localhost in server name?

In the "Advanced Outgoing Sever (SMTP) Settings" dialogue box, NO matter which
SMTP server is set default, always the first/top SMTP server in the list is
used. Fail as a different ISP is used.
