I built the dovecot antispam plugin and renamed it so I could have multiple backends installed at the same time. http://johannes.sipsolutions.net/Projects/dovecot-antispam I tried recompiling antispam without renaming the .so and I get the same result indicated below. All other plugins and the system as a whole has been functioning normally. Only when I add antispam plugin does dovecot not start and perform as expected. What can I do to find the reason dovecot is not loading lib90_antispam_mailtrain_plugin.so successfully? Below is some info I could think to supply for help.
