That's a good point.  When implementing a POP3 server with APOP support,
one should add an element of randomness so that the banner is always
different.

The RFC states:

"The syntax of  the timestamp corresponds to the `msg-id' in [RFC822], and
MUST be different each time the POP3 server issues a banner greeting."
