[Dovecot] zlib plugin "undefined symbol: imap_module_register"

[Alexander Weber]

Hi all,

i've tried to enable the zlib plugin within die LDA, but i've got some 
strange errors

dovecot: lda: Error: 
dlopen(/usr/lib/dovecot/modules/lib30_imap_zlib_plugin.so) failed: 
/usr/lib/dovecot/modules/lib30_imap_zlib_plugin.so: undefined symbol: 
imap_module_register
dovecot: lda: Fatal: Couldn't load required plugins


am i missing something within the config?

doveconf -n
