Re: Migrating mailboxes, which tool to use?
[In reply to]
POP3 relies on UIDL values to track messages. When a POP3 client sees
unknown UIDL values, it will assume a message hasn't been retrieved yet.
In DBMail these are generated during delivery and stored in
Other servers will use different UIDL values, and transporting existing
UIDL values into DBMail is currently not supported.
Maybe dbmail-deliver could be modified to support UIDL values on the
command-line. Or we could scan for X-UIDL headers and use those.
