Hi Eugene and Stephan,
doveconf -a | grep sieve
managesieve(root): Fatal: Plugin 'editheader' not found from directory /usr/lib64/dovecot/sieve doveconf: Error: managesieve-login: dump-capability process returned 89 managesieve_client_workarounds = managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 managesieve_sieve_capability = sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags sieve_global_extensions = variables sieve_plugins = editheader service managesieve-login { executable = managesieve-login inet_listener sieve { protocol = sieve service managesieve { executable = managesieve protocol = sieve unix_listener login/sieve { mail_plugins = quota sieve mail_plugins = quota sieve
sievec -d -x +editheader /etc/postfix/sieve_add_xorg.sieve sievec(root): Fatal: Plugin 'editheader' not found from directory /usr/lib64/dovecot/sieve
( with added "require ["editheader"]" in my sieve file )
find / -type f -name editheader.txt /opt/dovecot-2.2-pigeonhole-0.4.3/doc/extensions/editheader.txt /opt/_dovecot-2.2-pigeonhole-0.4.3/doc/extensions/editheader.txt
( these are files from tests i did with manual compiling the pigeonhole sources, not used at all and deleted in the meantime).
Stephan, i was testing some things and the general mail delivery fails when loading the plugin like you can see in this doveconf output. So in my first mail it wasnt present at specific time, but it is for sure and giving me same error over and over again with failing mail delivery.
Thanks in advance.
