 |This will be done in these versions with parameters like this:
 |  SERVER=pop MOUNT="[^@]* pop://YourPopServer/*[%0@titi..]"
 |Yes, I must correct or write something about this in "Manual.htm"...

I noticed that above "[^@]" is not necessary, that is just like

  SERVER=pop MOUNT="* pop://YourPopServer/*[%0@titi..]"

will work too.

 |>Though if you send

 |The pattern "[^@]*" means the MOUNT will be applied only if a
 |candidate string, POP user name in this case, does not contain
 |"@" character.

The reason why a user name with "@host" is not rewriten by MOUNT="* ..."
is that such user name is rewriten to a canonical form like "//host/user"
before applied MOUNT, and MOUNT="//* = default" (which means don't rewrite
user if server host name is specified by a client) is defined by default
for a DeleGate with SERVER=pop.

>   MOUNT="user1 pop://host1/*" ... let the "host1" be the server of "user1"
>   MOUNT="//pop2/* pop://host2/*" ... hide real hostname "host2"
