web-based email

[Rudy]

I run a small ISP (www.monkeybrains.net) and would like to provide web-based email.

I plan on using POP3Client.pm.  Is there any code out there which already utilizes 
POP3Client for web-based email (I'd hate to reinvent the wheel for the n_th time)?  
I'd like to check it see common email functions and problems you have already solved.

I'm leaning toward using POP3Client and EmbPerl.
