I've installed POP proxy using delegated POP3. Our user distributed to
several servers. And we don't want our user to input user@server to their
email client configuration.
We already using POP3 mount to meet that requirement. The configuration in
our delegated start up :

-P110
SERVER=pop
ADMIN=admin@domain..
MOUNT="user1 pop://server1.domain.com/user1"
MOUNT="user1 pop://server2.domain.com/user2"
MOUNT="user1 pop://server3.domain.com/user3"
.....

But we found, only 256 users on the top of configuration that could use user
and password on their email client. The other should use user@server on
their mail client.
Is there any limitation of POP3 mount configuration ? And how to increase
number of POP3 mount ?

Another question, how much memory used to every connected session to
delegated ?

Thx
