Hello i have had 1 Personal server for years with httpd and OpenSMTPD mail server working correctly; thanks OpenBSD Team.
But now i have another server for 500 Colleagues with OSMTPD + Dovecot + Dkimsign working well; but i ask, if it were possible to use only OSMTPD with virtual users + Dkimsign? Please tell me what i might read. Thanks .
