Outlook receives but does not send e-mail.

[Guest]

I have not been able to send e-mail through Outlook for months, although I
receive e-mails with no difficulty. I have redone the settings per the ISP's
instructions dozens of times, with no results. If I disable Norton Internet
Security 2005, perhaps 1 message might go through, but no more. In addition
to Norton Internet Security I have a D link DL 704 router.

Quincy,

I've posted a similar thread. What kind of error messages do you get? I'm
getting 503 error messages that say "503 Valid RCPT TO <recipient> must
precede DATA" when there are actual, valid addressees in those lines.

Is this similar to your problem?

Hi Darrell:

Thanks for your quick response. The error message I get is 0x80040601; Mail
delivery error.

When I hit "send" after drafting an e-mail, the message goes to the Outbox.
If I then hit "send and receive" then the notification is that Outlook is
receiving messages from the server, but there is no reference to sending any
messages to the server.

Quincy,

I typed your error code into Yahoo Search and found some really good
responses. Try it yourself and/or follow this link:

Could be the router's MTU setting. See
