• Email Quota — Each IMAP email account has a 1 GB disk quota on the post office server. You should check your post office quota regularly and archive old mail to keep yourself below quota.
• PCMCIA — Short for Personal Computer Memory Card International Association
• Phishing — an illegitimate solicitation via email for personal information, disguised as coming from a legitimate source. They often ask for usernames and password. THESE MESSAGES SHOULD BE IGNORED AND NEVER RESPONDED TO.
• POP (Post Office Protocol) — POP (Post Office Protocol) was the recommended method for accessing your mail before IMAP (Internet Message Access Protocol). POP is a basic store and forward mail handling system. When you connect to the mail server, your mail is downloaded to your machine (or home directory on Athena) and deleted from the server. It does not support reading mail from multiple locations or have the modern message handling features of IMAP.
• Purge (email) — Purging email is when the messages you have marked for removal by the delete command are erased from the server or your local computer drive. Once email is purged it cannot be recovered. Be sure you have archived or do not need any messages marked for deletion before you issue the purge command.
