Mail Can't Send To "NULL"

After adding an iPhone to my setup, suddenly Mail has decided not to send on the first try from certain accounts. I get a long message that basically says "Mail can't send from account 'NULL', select another server". So I click edit and re-send and the mail goes out fine on the original server that had been specified – I do not select another server as the dialogue box suggests.

Is there anyway to fix this so I don't have to send every e-mail twice?

MacBook Core Duo 2.0, Mac OS X (10.4.11), 2GB RAM/160GB 7200 HD

Try changing the port to 587 instead 25 in Mail.

If that doesn't work, try tias...

Try this.

Highlight the 'goofed' account in Mail Prefs. Go to Mailbox, and take it Off Line.
Write your message, but before pressing Send, go to Mailbox and click 'Go on Line'.
