Hi all....
OK! It happened again and I was able to save the error message:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'rgletters@guardnet.com'. Subject 'Letter to the Editor...', Account: 'pop.efn.org', Server: 'mailhost.efn.org', Protocol: SMTP, Server Response: '554 <rgletters@guardnet.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
Somehow Avast plays a role in this because this never happens when Avast is not installed. And again, this only happens when I click on a link on a web page, never from the main program.
Best Regards...
