If your damtp account was set up before Michaelmas Term 2005 and you are using the damtp email server, temporary redirections are a bit more complicated. You need to insert the following into your .forward file.
# Exim filter << DO NOT REMOVE deliver you@ your.forwarding.address
To redirect your email and keep a copy in damtp put the following in your .forward file
# Exim filter << DO NOT REMOVE unseen deliver you@ your.forwarding.address
You can combine this with spam filtering and other types of exim filtering.
This is a sample .forward file with the above which you can download and customize
For permanent redirections while you are in the university please redirect your @cam address and we will redirect your @damtp email to @cam for you when asked.
