Hi Timo, Thanks for the quick reply.

No not 100% sure that the UIDLs are the issue; but running into dead ends with what I have tried. I will compare the UIDL lists from the old / new server and report back. > However when I connect via POP3 the Read/Unread status is not preserved. > Another possibility would be simply that if you changed the hostname in the > client config, it might have thought that it's a completely different server. The new server is a completely different host and currently had a different IP, but it will end up with the same name and IP as the existing host when we cut over. At this time I have manually adjusted my lost hosts file to point towards the new host for testing. Would this be a problem even though the IMAP appears to be working were as the POP is not.?? I'll report back on the UIDLs Regards, Steven
