Hi. I have ispconfig3 with squirrelmail installed through the Perfect Server - Ubuntu 10.04 manual. I always use POP3 for the mail, so when you download mails with your client (thunderbird or outlook) they dissapear from the server. Now some clients ask me to use IMAP, since they have the same accounts in various PCs, and want to have them sincronized. No problem with this, it works too, but, with IMAP, mails will allways be in the server, and I don't have enough disk space (you know, people never drop any mail, even the trash folder, and it keeps growing and growing). Is there some configuration (on the server or in the client) to make imap accounts to keep mails on local on all PCs but remove them from the server?
