Hi,
I have a problem with my Dovecot IMAP Server on Debian Linux.
I migrated it from FreeBSD to Debian, but since then the HIGHESTMODSEQ value for INBOX is not increasing, when I receive new e-mail.
This causes my Groupware not to report any new e-mail via ActiveSync.
Here is the protocol transscript:
[I] <~>-> openssl s_client -crlf -connect mail.forberger-online.de:993 CONNECTED(00000003) [...]
read R BLOCK
- OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN AUTH=LOGIN] Dovecot (Debian) ready.

The Groupware's IMAP client library is reporting, that MODSEQ is not increasing. It stays at 190086, nevertheless I receive new e-mail.
I have tried the commands doveadm index and doveadm force-resync on the INBOX, without any change.
My filesystem where the mailboxes reside is on ext4.
Can you help me what is wrong?
Best regards,
Ronny Forberger
