    Your server has unexpectedly terminated the connection. Possible causes for
    this include server problems, network problems, or a long period of
    inactivity. Subject 'XXXX.rtf', Account: 'verizon', Server:
    '', Protocol: SMTP, Server Response: '421 Lost connection to []', Port: 25,
    Secure(SSL): No, Server Error: 421, Socket Error: 10053, Error Number:

    Westell ethernet modem
    Linksys BEFSR41 4 port router- MTU set to 1492
    Outlook or outlook express

    I simply cannot send any messages other than the most simple short text, no
    attachments at all.

    This has been going on for over a week now.

    Any suggestions? Desperate.

    It means service not available, closing transmission channel. Is that
    the only SMTP for your ISP? Is your client configured right?

    How is the e-mail being managed? That is, using POP3 to
    download e-mail to the computer and erasing them from the server? Or using IMAP and keeping all e-mail
    on the server? Possibility of running out of
    storage space since this is a relatively recent development.

    Not wise. The average person will not be able to setup and run it securely
    enough. An unsecured SMTP server on a DSL/Cable line is a spammers dream.

    Most ISP's also block port 25

  8. -OR- If you already have your own ISP SMTP server, you could try That will let you get around the port 25 block and
    send to a pre-exising server. Check out the site for more details.
