"Instant expunge" affects what happens when IMAP users delete +messages. As you may already know, messages are not truly deleted +when an IMAP client sends a delete command; they are only marked for +deletion. The IMAP client must also send an "expunge" command +to actually delete the message. The Citadel server automatically expunges +messages when the client logs out or selects a different folder, but if you +select the Instant Expunge option, an expunge operation will automatically +follow any delete operation (and the client will be notified, preventing any +mailbox state problems). This is a good option to select, for example, if you +have users who leave their IMAP client software open all the time and are +wondering why their deleted messages show up again when they log in from a +different location (such as WebCit).
+"Allow spoofing" refers to the security level applied to
+non-authenticated SMTP clients. Normally, when another host connects to
+Citadel via SMTP to deliver mail, Citadel will reject any attempt to send
+mail whose sender (From) address matches one of your host's own domains. This
+forces your legitimate users to authenticate properly, and prevents foreign
+hosts (such as spammers) from forging mail from your domains. If, however,
+this behavior is creating a problem for you, you can select this option to
+bypass this particular security check.
