Outlook Express Send Error

Specs: WinXP Home, 2.53 Ghz / 512 Mhz R

Just started 2 days ago. I can only receive e-mail through Outlook Express. Send fails. Error message is -

"The connection to the server has failed. Account: 'mail.comcast.net', Server: 'smtp.comcast.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E -

I think the problem is on Comcast's end because this problem is occurring on 3 different computers on this modem/router. Comcast says the error code probably means I have something typed in wrong. Unlikely. They had me delete an identity, them add it again. No help. Then I had to go to work and they said they would "refresh" my accounts and it would probably work. After work today, still same problme. Outlook express on all three computers will fail on "send," but "receive," works fine. I can go to the website and compose, send, and receive e-mail properly. Any ideas? We need to help Comcast technicians.

I am on Comcast and I can send just fine right now.

In the Account Options do not select either Logon using Secure Password Authentication nor My server requires authentication.

On the Advanced tab and under Outgoing mail deselect This server requires a secure connection (SSL). (Same is true for incoming)

I believe this later setting is your issue.


P.S. Should have posted this in the Office Forum.

Thanks for the info. I didn't see the Office forum. I haven't been to computing.net for quite awhile as haven't had any problems.

I unchecked what you suggest on my laptop. Other 2 computers were already unchecked. Problem remains. Still cannot send, won't connect to smtp. I figured this would not solve the problem because as I stated in the original post I have 3 computers that are all having the same problem. I have been using this setup with comcast and the modem and router for about 4 years with no problems. Kind of odd that all three would experience the same problem at the same time. I have booted the modem and router, no help.

Try Port 26 instead of 25 and use SSL.
AT&T changed awhile back to SSL and use Port 465.
That might work too but I have no idea?

I just had an intelligent thought flash through my head and Googled.


I think your answer is here. Same numbers as AT&T.

Wow, hey Cuffy! You genius! And I'm not even going to call the Comcast techs and tell them how to use google to read their own website to fix the problem that they can't fix for me. lol!

When I put in 587 for smtp, and put check mark in "this server requires a secure connection" the POP3 number changes to 995 automatically. And it HAS to be 995. Under "servers," I had to check, "my server requires authorization" because I wasn't receiving (after I started being able to send, I was not able to receive), and "log on using Secure Password Authentication" has to be UNchecked. I don't know why, but both send and receive now works fine!

Give yourself a pat on the back!

Now if I could only figure out how to unravel the mess they have made of personal web pages. Wow! They made "improvements" and I'll never figure out how to use them. Guess I'll post to the web forum one day when I get some time. Thanks again for the award winning tip. google, dam, will I ever learn? lol. However, I wouldn't have thought to specifically search "Comcast email port numbers." So you get kudos for those keywords.

The best advice I can give you to search with Google is to use the fewest and simplist words you can think of...........
where: comcast
what: port numbers
which port numbers: email
Just remember the olf adage... KISS
Google has more knowledge than we can imagine but the poorest damned thought process I've come across in years.
