Does anybody have an explanation as to *why* they stick X-UIDL headers
in? And why haven't they stopped now that they've read this?
X-UIDL headers are added to messages by some POP servers when a client
retrieves the messages. This header field is used to help keep local

Valid X-UIDLs are random 32-bit numbers, it appears. There are a number
of instances where the field contains repetitive characters, and these are
easy to trap:
* ^X-UIDL:.123a123a123a*
