THE PROBLEM: I cannot send an email to my own email address (@ my ISP). The
error message says:

An unknown error has occurred. Subject 'test', Account: 'centurytel',
Server: 'mail.nw.centurytel.net', Protocol: SMTP, Server Response: '550 5.7.1
lB6LnOr2023656 This message does not comply with required standards.', Port:
25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC69

We have two computers connected on a home LAN. Both use Outlook Express 6
for email, with Windows XP SP2. Until the day before yesterday, we had no
problem sending an email to our own address. When the problem first occurred
on one computer, the other one could still send email to same address. The
next day, neither computer could.

SOLUTIONS WE HAVE TRIED:
Changed the outgoing server to SMTP address given by ISP
Incoming mail server (POP3) address verified as the one specified by ISP
Checked the box "my server needs authentication" (had been unchecked -- ISP
says it must be checked with SMTP address)
Ran "NETSH INT IP RESET TEMP.TXT" and restarted computer
Tested sending a message from ISP's webmail -- that works
Tested turning off antivirus software and attempting to send message -- get
same error
Scrutinized Outlook Express settings for anything that has changed (did not
find anything)
Scrutinized antivirus update logs for anything unusual during that time
frame (found only routine pattern updates)
Asked a friend with same ISP service and Outlook Express to send a test
message to herself -- it worked with no problem

Our ISP says the problem is with Outlook Express or the antivirus software
(Trend PC-Cillin). Because turning off the antivirus did not solve the
problem, that seems to eliminate the antivirus as a possible cause. Because
the problem occurred suddenly on two separate computers, neither of which had
been consciously changed, we cannot understand how Outlook Express could be
causing the problem, nor do we have any idea what else to look for. Because
our friend was able to send an email to herself, that confirms that somehow
the problem must be here and not with our ISP. But we have no idea what else
to look for.

Is there any setting in Outlook Express that might cause this problem?
Any other ideas?

Are you using a router? If so, try disconnecting the power from the router
for 20 seconds, then put it back on. You don't need to reconfigure it or do
anything. You will get back online in about a minute or two. Some routers
get stuck with certain sites, causing them to be blocked, until you cycle
the power. Try it first. This is known to happen with Linksys and Belkin
routers, I am not sure about other routers.

That's always a good first-effort solution but I'd like
to add that it takes mine over 30 seconds before it
"forgets" everything. So it might be worth maybe a
minute off just to be sure, unless you have docs that
say it can be shorter.

The error message is really self explanatory. The email is not acceptable
to either your mail carrier or the ISP you are connected to. If you are not
connected to Century Tel then use the SMTP server for the ISP you are
connected to (assuming you have an account with them). Otherwise see if
Century Tel has a port other than port 25 that you can use with their
defined security settings.

Tried disconnecting router. Left it disconnected for 15 min. Same error.
Also tried disconnecting modem. Same error.

Do not send email

To me, the error is not self-explanatory, as it does not say what standards
are not being complied with, whose standards, why standards changed overnight
so that an email complied the day before but doesn't today, and what I do to
comply with these mysterious standards.
I am connected to Centurytel -- that has been my ISP for 17 months. Why
should the port in use all this time suddenly not comply with somebody's
standards?
If indeed I need to change the port, how do I do that? That was not
something my ISP even mentioned when I discussed the problem with them, but
on the other hand, I'm asking my question here because my ISP tech support
hasn't solved the problem.

Well, the problem isn't OE, I can tell you that. The error "Mailbox not
found" error is coming from centurytel's SMTP server, not OE.

Is Email Scanning still disabled? Does the behavior persist in a new
identity (File Identities Add new identity)?

Email addresses are usually case not sensitive, but the passwords usually
are. Also, how you fill your logon details might matter. Is your logon
account "Longshadows", "LongShadows", "longshadows", or
"longshadowsATcenturytel.net"? It depends on what your ISP says.

From your ISP FAQ:

How do I configure my e-mail client for pop mail?

The information below is needed to configure an e-mail client to check your
mailbox:

- Username: The account username that you want to check.
- Password: The password that goes with the username you entered.
- Incoming Mail (POP3) Server: mail.so.centurytel.net
- Outgoing Mail (SMTP) Server: smtpauth.centurytel.net
- SMTP Username: The account username that you want to check.
- SMTP Password: The password that goes with the username you entered.
