    Everytime I try to send a email through Outlook Express I get this error... I'm running RHEL, with WHM 8.8.0 cPanel 8.8.0-R73.

    Also running APF and BFD.

    Error is:

    "The connection to the server has failed. Account: 'Account Name', Server: 'mail.domain.com', Protocol: SMTP, Port: 26, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E"

    Are you using port 26 because you know port 25 is blcoked by your ISP?

    I would recommend going to Start -> Run -> type "cmd"

    At the prompt type:

    Code:
    telnet your.server 25
    
    Also try putting 26...Let me know what the results of both of those look like :)

    what difference does that make. Also, if at any future time, they want to use their own mail server, juz changing the IP of mail in the db will do in the previous case.

    It just was my experience....

    Bug? Maybe... Remember this has to do with sending emails.

    no.. then something is wrong with your server setup.

    Either mail.yourdomain.com is not resolving to your server or, it has got a different IP where that server wont receive mails for your domain.

    If mail.domain and domain has got the same MX, they both should work.

    A lot of ISPs are now blocking port 25 - fyi :)

    Some also block `sendmail` not just port 25.

    One of my customers has this problem too, goto cmd, ipconfig /flushdns
    then reboot the computer, if you are using OE then open it up, re-enter your password for that account -- > save, then reboot

    Are you sure. How could the destination mail server know that the mail was sent by sendmail. :-\

    Jemshi - Honestly? I Have no frigging idea, but it has happened to me

    I could send email, (So it looked) the server request and everything was fine.... but then *bang* noone got my emails, no matter what, so I called my isp and felt like telling the manager who set it up to f*ck off, but I held my ground, anyway, what ever port I used did not work.... No idea why or how, pop3 worked - smtp did not :(

    So I now use their mail servers. Bastards. (They say I can remove the block by `upgrading` my account to a plan thats like $100/month)

    But what the heck :) so now when ever one of their servers goes down I call them up about 50 times and wine about it and saying if the cap was not there we would not have me calling in..... anyway, they have yet to remove it.

    I have tried using smtp on port 26, 995, 25, and a few others - nothing, its my isp though, I would say to the thread starter, get them to call their ISP and ask if they block port 25 or sendmail
