Paul thx for your time and help!
After a long time of testing i noticed something... probably a small thing
for a dovecot expert...
The seen mails of the old server have a ",S" at the end of the filename.
The seen mails of the new server have a ",:2,S". If I rename the mails
before the import, the
1) "sieve_user_email = %u" creates a warning: "Warning: sieve: Invalid
address value for setting `sieve_user_email': Missing domain"
That warning is a glitch, ignore it. I mentioned it on the list before
but has not been fixed in any of the updates.
What I am currently trying to figure out
