Windows Mail

[Jackad]

I can receive mails without problem but suddenly - from about mid-day today I
can no longer sent them. If I go to the website of my ISP, I have no trouble
sending them.
The error message I get is :
An unknown error has occurred. Subject 'Return of Card', Account: 'E-Mail do
SAPO', Server: 'smtp.sapo.pt', Protocol: SMTP, Port: 25, Secure(SSL): No,
Error Number: 0x800CCC0B.
Any help/suggestions much appreciated !

"Unknown error" can be caused by interference from an antivirus
program. Which antivirus are you running?
As a minimum, email scanning in the antivirus should be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

Email scanning in any antivirus should be disabled, for reasons
explained here:

Thanks for your response. I'm using Sophos A-V and have been using it for the
last 10 years witout problems.
I'll try your suggestion and let you know how it goes.
