[NBLUG/talk] Cant' Send Email to Self

[Howard]

My Email account is through att.yahoo. I can send email to an external
account e.g hotmail. When I send email to myself the message does show
up in the sent folder, but when hitting the send/receive button it never 
downloads
in my inbox. Tested with both Evolution & Thunderbird on Ubuntu Desktop 
10.04
I have Apache installed. May there be an issue because of the HTTPD server??
Thunderbird Error consolde gives me the following

pop.att.yahoo.com : server does not support RFC 5746, see CVE-2009-3555
