I scanned all of the previous questions about E-Mail but didn't see anything that fit this. I sent an E-Mail to a list of people. One of the addresses was rejected by my server (we are on the same server but she closed her account). Problem - I have deleted the message but every time I send anything Outlook Express resends it and of course it is rejected again. Any ideas?

Check your outbox and delete it from there.

It could be that your SMTP is not valid. I am not an expert but this is what I had to do with my computer.

If there was an SMTP problem NO mail would be getting out.
