I would like to configure OutLook Express so that it does not
attempt to resend eMails in the Outbox folder whenever new
sends are made From Access. The ISP's server rejects some
eMail address immediately...

Things like JohnDoe@aol. (an incomplete address) and sometimes
NonExistent@NorthState.net (if NorthState is my ISP, its mail server
knows IMMEDIATELY that NonExistent is NOT a valid mailbox in
their system.

So, the mail server immediately rejects the msg & OutLook Express
stores it in the Outbox folder. Each time Access attempts to compose
and send a new eMail, OE tries to send the problematic one in the
Outbox again. Of course, this results in Outlooks error msg popup...

"Some errors occurred while processing the requested tasks. Please
review the list of errors below for more details. The message could
not be sent because one of the recipients was rejected by the server.
The rejected eMail address was 'BlahBlah@aol.' ... "

Well, you get the idea - my automated procedures are interrupted
until I manually go into OE, open the Outbox folder, delete the
problematic eMail, return to OE's error pop-up msg & click OK. Then
the processes resume.

Can I configure Outlook Express so it doesn't send any outstanding
msgs sitting in the Outbox folder when a new eMail is processed?

Suggestions appreciated.
