550 not a local host error - only for the last account

Hi,

I have this weird error. I have many accounts set in my Outlook: mail1,
mail2, mail3 etc. *All* of them have the SMTP authentication enabled.
Whenever I send a message using the last account, it returns a "message
is not deliverable" mail immediately (550: Not a local host).

If I had 3 accounts and if I opened another account, mail4, then mail3
won't return any error but mail4 instead. Have you seen anything like
this?

I use Office XP (updated) on Windows XP SP2.

Ensure your send/receive polling interval is set to at least 10 minutes,
longer if you have several accounts. Sometimes, a shorter srs can step on
one or more mail servers and cause the error you report. If you have more
than 6 accounts, I would set the send/receive settings to 15 minutes.

I see.

It's about 10 accounts at each of the 4 computers (accounts are
different on the 4 computers but the mail servers are the same) and S/R
intervals are less than 15 minutes on each computer. I will try to
convince people to increase the interval (they are obsessed to see
their mail at the second it arrives :)

Thanks!

Could you turn on diagnostic logging (see

the OPMLog.log file after you've had this problem?
