HELP - trouble sending e-mail

[Guest]

I have recently installed a Linksys wireless-G broadband router onto my
cable-modem. My Home PC is the main computer in the household. I only use
(1) laptop to access the wireless network within my home. My laptop computer
has no problems accessing the wireless signal OR accessing the signal if I
plug into one of the additional (4) available ports. My laptop has no
problems receiving e-mail messages OR accessing the internet. HOWEVER, I am
having difficulties attempting to SEND e-mail.
I am a frequent business traveler and I DO NOT have these problems at hotels
offering wireless hi-speed internet. I have contacted Linksys tech-support
and they say that it is due to settings WITHIN Microsoft Outlook 2003.
A little background on attempting to SEND e-mail ... I am utilizing
Microsoft Outlook 2003 to access a web-based e-mail client (Merak Mail
Server). I do not know if that has any bearing?
Both my Home PC and laptop are running Windows XP.
If anyone could possibly offer any assistance / direction for these issues I
am having, I would greatly appreciate.
BEST REGARDS

When you use the 'Test settings' option within OL, what errors are reported?
Possibly also a Firewall setting
