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

[denoxis]

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.

This is most likely a connection issue with the smtp server. You don't give
any information about how you connect to the Internet or who your ISP is.
Typically, most ISP's will allow you to send through their SMTP server located
on their network. If you connect to the internet later through a different
providor, you will most likely find that you can not send through your other
ISP because you are no longer connected to them. Also, many ISP's are now
blocking port 25 for all other smtp servers except the ones within their
network. Your best bet to test things is to obtain the name of the smtp
server you are trying to send through. Get that name from your account properties.
Then go to a command prompt and type TELNET <nameofserver> 25 and hit enter.
If you are able to establish a connection then Outlook should work. If
you can not make a telnet connection then don't waste time troubleshooting
Outlook. The problem needs to be taken up with your ISP. Hope this helps...

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?
