dovecot - Feb 2014 - dovecot antispam plugin not found

Hello,

I'm trying to setup dovecot-antispam, and even though the configuration
and the installation seem to have gone well, dovecot is telling me it's
not finding it.

Here is the symptom:

schmitta at top-wifi ~> /usr/local/Cellar/dovecot/2.2.10/libexec/dovecot/imap
-c ~/.dovecotzimbra.rc
Fatal: Plugin 'antispam' not found from directory
/usr/local/Cellar/dovecot/2.2.10/lib/dovecot

However there seems to be a plugin there:

schmitta at top-wifi ~> ls -al /usr/local/Cellar/dovecot/2.2.10/lib/dovecot/
| grep antispam
-rwxr-xr-x   1 schmitta  admin    38460 18 f?v 22:40
lib90_antispam_plugin.bundle

I note that it is the only plugin with the ".bundle" extension, if
it's
important.

My configuration file is as follows (I'm not finished with the antispam
configuration yet):

--8<---------------cut here---------------start------------->8---
protocols = imap
mail_location = maildir:~/.Maildir/zimbra:INBOX=~/.Maildir/zimbra/.INBOX

default_login_user = _dovenull
default_internal_user = _dovecot

protocol imap {
#  mail_plugins = $mail_plugins antispam
}

protocol lda {
  log_path = ~/.logs/dovecot-lda-errors.log
  info_log_path = ~/.logs/dovecot-lda.log
  mail_plugins = $mail_plugins sieve
}

plugin {
  sieve = ~/.dovecot.sieve
  sieve_plugins = sieve_extprograms
  sieve_extensions = +vnd.dovecot.filter
  sieve_filter_bin_dir = /usr/local/lib/dovecot/sieve-filter

  antispam_backend = DSPAM
  antispam_signature = X-DSPAM-Signature
}
--8<---------------cut here---------------end--------------->8---

Should I do something special to be able to load the antispam plugin?

Thanks,

Alan

You are not running a full Dovecot install, so doveconf -n is not working?

what OS is this?

Did you've seen some like this:

make install
Entering directory src.
Leaving directory src.
Entering directory doc.
Leaving directory doc.
Entering directory src.
Successfully installed lib90_antispam_plugin.so.
Leaving directory src.
Entering directory doc.
Successfully installed dovecot-antispam.7.
Leaving directory doc.

Does build.mk contain "LIB_SUFFIX=.bundle" ?
What happens if you rename lib90_antispam_plugin.bundle to whatever the 
other plugins are named?

Did you've seen some like this:

Leaving directory src.
Entering directory doc.
Leaving directory doc.

Successfully installed lib90_antispam_plugin.so.

Hello Steffen,

Long story short: changing the plugin extension worked, thanks! Now for
the details ...

doveconf -n is working:

Almost (the extension of the plugin was different):

--8<---------------cut here---------------start------------->8---
schmitta at top-wifi ~/s/dovecot-antispam-plugin> make install
Entering directory src.

No. I don't have a "build.mk" but a "buildsys.mk", and
it has the
following regarding LIB_SUFFIX:

--8<---------------cut here---------------start------------->8---
schmitta at top-wifi ~/s/dovecot-antispam-plugin> grep LIB_SUFFIX buildsys.mk
LIB_SUFFIX = .dylib
--8<---------------cut here---------------end--------------->8---

That was it! Renaming to ".dylib" did nothing, but renaming to
".so"
worked (insofar as the plugin loaded, I'm getting the expected error
that antispam plugin folders are not configured).

Where should I report this building issue? Is there an antispam bug
tracker?

Thanks again,

Alan
