Outlook: sending emails problem, but OK when replying

We have a client with a problem with just one user sending (POP) emails using Outlook

When he sends emails they apparently don;t arrive at the destination addresses on the same domain

However, he can reply to emails that are sent to him from the same domain and he can send emails to the other domain users from his domain email address from his Blackberry but not from his Outlook on his PC.

I have asked him to make sure that he sending correctly addressed emails (when he replies the address is there automatically I thought maybe he is picking up an incorrect address from the auto-complete or from his address book in Outlook), but apparently not so.

Any obvious cause with his Outlook set-up?

Thanks

check the smtp server or router ip he is using. it might be black listed therefore no error report about non delivered mails and the mails are lost.

It's unlikely because no-one else in the company with the same domain is having any problems sending emails.

Also he can reply to emails OK, but they "disappear" if he sends an email.

then automatic filters in outlook

The only filters I know in Outlook are the spam filter and Rules. Is this what you mean? If so then it would have to be filtering outgoing messages in this instance?

We now have some more inforamtion from the user and we think his ISP may be blocking the company domain.

We have asked him to contact his ISP (he is based in Bangkok). We are awating an outcome.

What is really odd is when sending emails from his domain the emails bounce (for all recipients), but refer to:
-----------------
The following recipient(s) cannot be reached:

      'Name' on 4/1/2556 6:27

            550 <name@otherdomain.co.uk> No such user here
---------------

But when sent from his personal domain they work OK.

you need to learn the difference between smtp and pop3, then determine what smtp server the user is using when sending mail and why he does not use your mail server for outgoing messages

I do know the difference between POP3 and SMTP.

As mentioned previously, it seems the problem is with his local ISP in Bangkok. We are awaiting the outcome of his discussions with them.
