Outlook 2003 not sending mail with Yahoo account on Vista machine

[Mozzi]

Unfortunately after reading as many questions in this forum on similar topics
I lucked out & have not solved my problem. I have been in contact with the
Yahoo tech team for over 6 weeks now without any success either.

I have Outlook 2003 on a Vista machine. On my previous XP machine I had 3
mail accounts: yahoo, gmail & gmx. All worked fine. Now on Vista, gmx works,
gmail works, but Yahoo does not. I can receive email, but cannot send.
Outlook keeps reporting an SSL / SSL authentication problem when sending...
(i.e. server found but does not respond). I have treid all recommendations
from Yahoo tech team concerning POP / SMTP servers around the world and their
corresponding SSL authentication & port settings... no change... I even ran
recommended repair tools from Symantec / Norton as well as checked all the
settings I could find in Norton Internet Security to allow Outlook full
access. Ironically gmail and yahoo use the same SSL port settings.

Any suggestions?

Repairing Norton is not the issue, removing COMPLETELY it's email scanning
is. Norton's email scanner, like ALL AntiVirus email scanners is NOT
compatible with Vista and must be removed. Actually none of Norton is
compatible with Vista, you should abandon it in favor of one that is, such
as Avast!, AVG, or NOD32. The Norton uninstaller will NOT remove
everything, you'll need Norton's removal tool:

Download and run the Norton Removal Tool

More words on the evils of email scanning are here:

3. Turn off email scanning in your antivirus software.
http://support.microsoft.com/KB/951805
Stop error message when you send or receive e-mail messages on a Windows
Vista-based computer that has e-mail scanning software installed: "STOP:
0x1000008E KERNEL_MODE_EXCEPTION_NOT_HANDLED_M"

Regardless of which AntiVirus product you elect on using, you MUST do a
custom install and make sure that the email scanning feature/module/service
is NOT installed.

Hi Hal, thanks for the hint. Here is my issue with your suggestion: why does
2 of my mail accounts work without problem and ONLY my Yahoo account does
not. It seems to me the email scanning is not necessarily where the problem
lies. Should that be surely all mail accounts would be affected, or?

Nope, individual accounts can have different problems or no problems at all.
Do all your accounts require SSL? I'm betting they don't and it's perfectly
conceivable that Norton would screw up the SSL requirements and have no
effect on accounts that don't use it. Again, Norton is the least friendly
of all AV systems and is more invasive that any malware it's designed to
keep out.

Hi Hal, I have tested by disabling Norton. Unfortunately the same result.
Also, Gmail servers use the same SSL settings and thus the ports required
(SMTP with 587 or 465) seem to be functional. It is only Yahoo. Any other
suggestions? Thanks in advance. Marcel
