I've seen one other post with the same problem and the cause in that case
was setting the Return Address to a non-AOL email address; the cure was to
replace this address with the AOL email address of the account used to send.
Here's what I found:

I have a client who's ISP is AOL. I am trying to set up Outlook 2003 so
that
it can recieve E~mails that have been sent to the address
" and obviously send E~mails as well,
sending obviously requires the use of the SMTP details of the clients ISP,
(in this case AOL)

I have read about needing to use IMAP rather than POP for the incoming
mail
server so when I created the profile I selected IMAP, rather than the
usual
POP.

For the incoming mail server I have typed "mail.stirlingnarrowboats.co.uk"
(this is the info given by the hosting company)
For the outgoing server I have typed "imap.aol.com"

On the screen where you type the incoming and outgoing server addresses
there is also a heading "Logon Information" I have entered the logon
information for the "stirling narrowboats" account at this point. Then on
the
"More Settings"; "Outgoing Server" tab, I have ticked the box "My outgoing
server (SMTP) requires authentication" and clicked on "Log on using" and
then
filled in the AOL username and password. I then clicked on the advanced
tab
and changed the Outgoing server port to 587.

I believe this should be everything I need to do.

Now when I open outlook with this profile it will receive all the E~mails
addressed to " HOWEVER when I try to
send I
get the error message "550 incorrect domain in mail/RCPT command"

Can someone please explain what this error message means and more
importantly provide a solution.

Many thanks (Sorry the post is so long but I felt it was important to try
and give you the full facts)
