Entourage 2004 and Proxy Server

Hi,

I've recently switched from Entrourage X to Entourage 2004.
Previously, I needed to re-configure my proxy settings in Entourage X
within Entourage each time I moved from location to location. (That
WAS a pain!) Now, with Entrouage 2004, there are no options to
configure for proxies within for Entourage and I can only connect to
pick up mail (IMAP, POP) if I have NO proxy between me and the 'Net.
This is ALSO a pain!

Note that I can configure proxies within OS X 10.4 Network settings
for general web applications, but do not see an option within those
settings that pertains to email -- IS there a method to make this
work, or do I need to re-configure my connection direct to the Net
each time I want to work with email? Too much work for such a simple
task!

Would really like to see this sorted out in short order --- and trust
that similar issues won't be present in Entourage 2008 ....

Thanks in advance to anyone who has a solution for this issue!
(Entourage 2004, OSX Tiger)
