Package: kolab-cyrus-pop3d
Version: 2.2.13-5.1
Severity: wishlist
The following patch allows the client to append "-NNN" to the POP3 username
in order to see only the last NNN messages in the mailbox. This is useful
for many mobile clients (in particular, those on Nokia S60 phones such as
the N85, N96 etc), where retreiving all headers in very large mailboxes is
a problem due to resource limitations.
