|The users have usernames in the format : user@host.. Initialy I configured Delegate like this
 |delagated -P110 server=pop  MOUNT=" * pop://servername/*". 
 |This did not work as delegate used the host part of the email to connect to the rmeote POP server so I tried fater i re-read the docs to have a default server for a specific user
 |delegated -P110 server=pop MOUNT=" user  pop://servername/*"
 |Delegate strangle, after this modification and other  mount options that rewrite the target host server, still uses the host part of user@host to connect to the target server. 

If all of your clients are to be hosted with the server "pop://servername"
then

  delegated -P110 SERVER=pop://servername

without MOUNT, i.e. without rewriting username, will work.
Otherwise, if you have other MOUNT option(s), and "User@host" needs to
be hosted with the server,

  delegated -P110 SERVER=pop MOUNT="//host/* pop://servername/*" MOUNT=...

Generally forwarding "User@Host" to "pop://servername" can be represented
as this:

  delegated -P110 SERVER=pop MOUNT="//*%S/%S pop://servername/*%(1)@%(0)"

It might not be so peculiar if you know that in POP-DeleGate, "User@Host"
is translated to "//Host/User" internally before being applied a MOUNT.
