How to take away not all folders from the server on pop3?

Question

Email

Used by SquirrelMai, it contains user boxes.
The inbox includes: drafts, sent, trash, smap. Is there any way to keep emails out of the spam folder? Or exclude it.
Letters are collected using the pop3 protocol.

PS: There is not infinite space on the server, that's why POP3 is used.

Answer 1

No. IMAP4 can work with folders on a remote server (in fact, it was invented to replace the dull POP3).
