Can receive, but Can't send e-mail using att.net and yahoo
I can receive, but I can't send e-mail using att.net and yahoo. I have worked over 8 hrs. with a Yahoo Tech support guy, in India, to no avail. He said my IP address had been hacked by an e-mail. He installed a $79.99 anti-hacking software on my computer. He said my Safari browser was out of date, and reset it. Now he thinks my iMac (2 GHz Intel Core 2 Duo) running Mac OS X Version 10.4.11 is out of date and should be replaced. HELP!
I have an e-mail problem, why suddenly an iMac problem?
My e-mail preference file shows the following for my outgoing Mail Server. Incoming mail works fine.
Current Settings for POP Account:
My Outgoing Mail Server (SMTP): smtp.att.yahoo.com:my e-mail address
Server Port: 25
Use Secure Sockets Layer (SSL): box checked
Authentication: None
