I use my Bubba TWO to store my e-mail on the IMAP server. The mail is retrieved by Bubba from several POP3 accounts. I have once choice: "Leave email copy on server", yes/no

If I look at the Thunderbird e-mail client, I can specify the number of days to leave the mail on the server. I would find this useful, because I do not allow WAN access to the mail on the Bubba. I could check e-mail on the POP3 servers from other locations than home.

This is actually not super trivial as the "Yes/No" option just specifies whether the POP client gives a DELE command after RETR, or not. If you want specificity, the POP client (in this case bubba) must download all headers for all mails, digest them for date and do a selective DELE on those mails. Getting this idiot-proof and production quality in bubba is quite a bit of work.
