My hint would be that the deliver you use is not from v1.2
I never used v1.1, but v1.0 does not have no null_header_filter_callback symbol.
Maybe due to some "make install" in v1.2 without prior "make uninstall" in v1.1.16 .... ?
Uh, good hint, that binary is quite old, from 2007 ... the error was the line in /etc/postfix/main.cf, which configured the transport "dovecot" to use the wrong and old deliver-binary ... I adjusted the path now:
dovecot unix - n n - - pipe flags=DRhu user=virtmail:mail argv=/usr/local/libexec/dovecot/deliver -d ${user}
This lets me enable the lda-plugin sieve now, fine! Seems like that binary was left over from the former rpm or so ....

This was one step to success, now I have to debug the managesieve-part ... Horde's ingo always gives me "Not currently in TRANSACTION state" ... *sigh*
Thanks so far for the help!
