This is highly likely to be that the connection you are on blocks SMTP (TCP
port 25) outbound, which is what your mail client is likely to have been
configured to use to send mail. One thing you can try is changing your mail
client's settings to connect to each SMTP server on port 587, or
alternatively to use SSL and connect on port 465. If you don't understand
what I'm on about, let us know what mail client you're using and someone
can tell you where the settings are.
your MobileMe account likely works because it's been automatically set up
to use port 587 or 465, or some other port that's not usually blocked by
firewalls, as otherwise it would not be very 'mobile' ;)

I wonder if anyone can help me with this problem.
At home I am on a virgin cable link to the internet. I can send messages from a
variety of addresses.
When travelling, I usually find I can only use one of these mail out addresses.
Usually it's my .mac/.me address, rather than my own domain, though sometimes I
find the opposite.
I have no idea why this is, and on occasion it's very frustrating. Can anyone
help me understand and handle this?
Thanks a lot.
