Hi marcelo,

First of all, was the error when you were trying to send message or receive them, or both?  Next, did you recently install a firewall on your system?  It can block ports 25 or 110, which are needed to do POP3 and SMTP transfer.  Once we know whether it is just sending/receiving or both, we can have a better idea of what is occurring.

Also, I went to the MS knowledge base, and found this useful link for future reference:

I hope this helps.

Check the email address your are sending to:

<AL <al@myservername.com>

There is a missing bracket so the server is trying to figure out where the email address is.

Try sending a test message to just

al@myservername.com
without adding the persons name etc.

Re: your original post - It may be because of the Mydoom virus which sends itself over port 25, so many ISPs are temporarily blocking that address in order to slow down its spread.
