i try unbound & mailserver ( opensmtpd & dovecot ) in intranet before . it manages to run . but there is little informatio about openbsd in internet . are thre commprehensive URL about it ? i only to build minimum internet mail server for personal use , so OpenSMTPD is good choice because i hear it is simple and beautiful . |Unless you actually need some feature of Postfix, now there's OpenSMTPD, ---------------- regards
