I want to offer to my customer this possibility :

• get her pop3 emails from external pop3 server

• forward the news emails to the new external pop3 server

I have find lot of tools for sync imap accounts, or sync pop to imap, but i just want get pop and send to another email adress !

I search a answer for linux ( if i can make a simple daemon for make it's it's good ).

Thanks a lot for your help.

edit for more detail :

For simplify my question, in my use case, it's just want to connect as client via pop protocol ( like a mail app ). And i check news emails, and forward to other email adress. I search about an app or code for create this on linux.

In this situation have no access to mailbox dirs, or server configuration ( in this case i have already the answer by create a qmail hook )

Maybe, it's not the good website ? my question must be post on the stackoverflow part ?
