[patch] Improved error checking for the dovecot-antispam-plugin

Hi,

Hopefully this is the right channel for such a patch. I have a minor enhancement to submit for the antispam plugin

http://hg.dovecot.org/dovecot-antispam-plugin

It adds minimal error checking for the sendmail_binary, otherwise the reported error in case of a missing binary or one with missing permissions is generic and not useful.

Thanks,

Robert
