Re: Best practice integration of DSPAM into ma il system with separate Postfix and Dovecot VMs

 Thanks for your participation, but the link and example you provided
talk about sa-learn, which is AFAIK SpamAssassin's training tool.

Did you mean I should change the last two strings of this:

antispam_backend = dspam
antispam_signature = X-DSPAM-Signature
antispam_signature_missing = error
antispam_spam = SPAM
antispam_trash = Trash
antispam_dspam_binary = /usr/local/bin/dspam
antispam_dspam_args = --source=error;--signature=%%s

to this:
antispam_backend = dspam
antispam_signature = X-DSPAM-Signature
antispam_signature_missing = error
antispam_spam = SPAM
antispam_trash = Trash
antispam_mail_sendmail = /usr/sbin/sendmail
antispam_mail_sendmail_args = -f;%[email protected]
But such a config wouldn't tell the antispam plugin where DSPAM server is...
If I misunderstood you, please take a bit more time to explain your idea.

Thanks!
