Our web hosts in the USA are having performance problems and incoming Safespeed email is presently quite badly affected.
See this post from the Host's forums:

All our services can be affected by this. Visible effect might include pages that build slowly and you might get "gateway timeout" messages.
I have talked to the hosts on the telephone and they promise further load balancing efforts to smooth the problems.
Please bear with us while this is resolved and DO NOT send large email attachments until things are working normally again.
More news later.
