Hi Steffen,
wow, nice to see someone pushing for advanced protocol features :). A
successful BURL transaction depends on IMAP's GENURLAUTH because Trojita
needs to get an URL of the email's content for submission. Is that
supported by your IMAP server? Are the ESMTP and IMAP servers configured to
trust each other?
If this pointer doesn't solve it, let's move this to KDE's bugzilla for
further troubleshooting. We'll need the logs; activate them in IMAP ->
Debugging -> Show IMAP protocol log. The relevant stuff will be found on
both "Connection 0" tab (for generic state messages) as well as on the
highest-numbered tab for an actual IMAP log. The ESMTP bits are, sadly, on
stderr.
Cheers,
Jan
