[Dovecot] More Migration Questions

[Richard Hobbs]

Hello,

Thanks again - your reply will help greatly.

I have a rather more annoying problem at the moment, best described by
my conversation in the dovecot IRC channel...

i've telnetted to 110 on old server

the "uidl" command shows 3 UIDLs

uidl command also shows 3 UIDLs from new server...

trouble is, despite seeing the same 3 UIDLs on the old mail server *and*
the new mail server, when issuing the "uidl" command through port 110
after logging in, i just setup the account in my mail client against the
old server, downloaded 3 msgs, changed the config for the new server,
and it downloaded the same msgs again!

ok, on the old server, in the received email, towards the bottom of the
headers, i see this:

X-UIDL: a=="!(3N"!&D'"!87D"!

on the new server, in the duplicate received email, right at the top,
before any other headers, i see this:

X-UIDL: a=="!(3N"!&D'"!87D"!

whaton earth is going on here...

both now have the same X-UIDL, but are being downloaded separately!

So... does anyone have any ideas?

Thanks again!

Richard.
