Why can't I send email from all my accounts?

I'd say the solution is to run your own SMTP server locally and sidestep your ISP's SMTP altogether. I did that for a while in the '90s when I was a PacBell DSL customer and their SMTP servers kept crashing.

Unfortunately, many viruses and spambots use their own SMTP servers, as do real live spammers, meaning a number of ISPs are blocking port 25 traffic (the SMTP port) to combat spews of spam and virus-infected mail coming from infected PCs on their networks.

This is done to force you to use their outbound mail servers. Realize, though, that most don't require you to use your ISP username or e-mail address in the "From" line, so you can still send mail that appears to be from your Verizon account through the Comcast SMTP server.

Currently I have Mozilla Thunderbird picking up POP or IMAP mail for 15 different e-mail addresses through 4 servers, but I can answer all that mail from home and send it out via my Comcast SMTP server.

The only place this becomes difficult is when I'm on the road with my laptop. But my web host provides SMTP services (with login required), so I can send mail for most of my accounts so long as I have internet access.

i need to know is my comcast e-mail activated i also have a yahoo e-mail but i want to use my comcast as well

after trouble shooting Outlook error 0x80042109! I found that comcast has taken filtering of spam to a new level at the modem by turning off port 25 completely. There is a boot file in the modem that turns off the port. You must contact Comcast Abuse representives to turn it back on!

Jack, I contacted Comcast, but they insist port 25 is not blocked for me, even though this is the last possible solution! It is SOOOO frustrating. There is no way to contact their Abuse people other than email. Their phone number just gives a voice message saying to email them. Do you have a trick on getting the solution expedited?

i cannot recieve or send e-mail please help me

Why can't the people in my addressbook with COMCAST address receive my mail?? Is it my problem or theirs??

Hi Leo, it's Leo just wondering if you know why I can't send a link from IE 6 to my own Email address?.This function of IE only failed after downloading (auto)WGA file(KB905474).So much for Win auto updates,I can't wait till someone comes up with a viable windows alternative.
I asked you because all us Leo's are smart and that's not a biased opinion.
Regards Leo
