If most, but not all, of your internal email clients are retrieving email from a single mail 
server, enter this as the Default POP server. Check Allow connections to other POP 
servers. 
If there is no single mail server from which most of your internal email clients are 
retrieving email, leave Default POP server blank and check Allow connections to 
other POP servers. 
Note 
For each of the email clients that is not retrieving email from the default POP server (this 
may be all email clients), the email client’s POP (or POP3) username setting must be in 
the form of user@mail.isp.com, rather than simply user – user is the POP login, and 
mail.isp.com is the POP mail server. 
Typically it is not necessary to adjust the POP protocol Request timeout. 
Once POP scanning is functioning properly, you may choose to Reduce syslog output.
