Port 25 automatically resetting

[Steve]

Thank you in advance for any responses to this....

I have Outlook 2003 with SP3 running on Windows XP with SP2.

I recently setup my Outlook to run email with Google's POP3 Gmail.
According to Gmail, the setting should have POP3 set to:

-POP3 Port 995 with SSL
-SMTP Port 465 with SSL

I did this and everything works GREAT!

However, after a little while (sometimes minutes, sometimes days), my email
stops working with the SMTP and I get the message that my ISP does not
support SSL Encrypted SMTP. This is strange because it WAS working fine.

After some research, I discovered that the Outlook program spontaneously was
resetting the SMTP port to port 25!

I tried to change it back to port 465, but it didn't work. I looked online
and there was a suggestion to delete that email account and recreate it. I
did this and it worked fine....UNTIL Outlook reset the port spontaneously to
port 25 again!!!

Why does outlook keep resetting the SMTP port to port 25 for this email
account?

I have Norton Internet Security version 15.5.0.23 (current) running. I
can't imagine NIS to be doing this, but I have no idea?

Help?

Is that a guess or you've actually tested it by disabling or uninstalling
Norton email scanning? I think NIS email scan is the culprit.

John - I have a support request into Norton about this. I was anticipating
them telling me that it is NOT NIS. Are there any known reasons (to you)
that would cause the SMTP port of an Outlook 2003 email account to change?

Past versions changed the server names so its not unreasonable to think it
changed the port.

The most likely culprit is that you have an email scanner (antivirus
or -spam) wedged between Outlook and the mail server. Uninstall your AV
program and reinstall it without ANY mail integration.

I've heard of quite a few complaints about "strange" Outlook behavior that
disappears when email scanning is either disabled or uninstalled completely.
Doesn't hurt to disable email scanning or remove email scanning option.
