Why not try and reconfigure the server without SSL and do a test...if
they all work..then i would say it might be the your outlook client
might be corrupt and you might need to reinstall them...
Or You could use another client to test apart from outlook..

All of the 4 PCs have personal firewall turned on, all have SAV real-time
protection on -- exact same settings. I also tried to turn off personal
firewall and SAV off, but on the 2 PCs that I could not send email before, I
still can't do it. On the 2 PCs that I can send email out, it doesn't matter
whether personal firewall and/or SAV is on or off, I can always send mails
out.

When I try to send emails out on the "failed" PCs, the maillog shows:

I also, tried on my FC5 system, the same situation. I just could not figure
it out why.

Thanks!
