open port 113 ?

[Fat Toolz]

Hi qmail,   I just opened the firewall on port 113, the logon is quite faster and I'm quite lucky to miss this dumb Outlook Express-Screen "Your Server has not responded for 60 seconds...." :-) . I want to enable POP3 from outside the firewall to the qmail-Server but I do not think it's wise to open port 113 from *outer space* to the qmail-Server through the firewall (remember that the port is also opened from the internal network). If 113 is used by qmail for authorization, probably I'll have to open it.   But what about starting tcpserver with -H ? Where are the differences and what about using tcpserver -H ? Do I loose security effects by starting tcpserver with authorization NOT on port 113?   Thanks. Stef   P.S.: Sorry for the big delays between my messages... It's messing me up today.
