[IMail Forum] Security Question

[imfo]

We run imail v5.07 on our internal network
Only SMTP packets are allowed IN through our firewall (Checkpoint FW-1)
What are the security implications of opening up each or any of
POP3, IMAP4, HTTP
to allow our users access their mailboxes from the internet.
I know we can install a security (encryption) module in the firewall (for
some $$$), but does say allowing POP3 access only compromise our security ?

TIA
Ronan
