What client are they using?
We see e-mail profiles get corrupted every once in a while. They look OK, but delete them and re-add and they work fine. See it more with OE than with Outlook, but have seen it with both.
Another poster had a valid point about port 25. Are they on their providers when they can't send?
Does the ISP have an alternative port? Some use 587 or 995 (usually SSL)?
