And that's the type of rule that frustrates me... I operate on a dynamic IP, but have an MX record that points at that same dynamic IP (and an SPF record to boot). Beats me that a large ISP will deliver mail to my domain to a (dynamic) IP, but then flatly refuse replies to those emails from precisely the same IP/domain combination (Australian ISPs in particular, much to my wife's annoyance). They're hypocritical, I'm cheap - which is worse ? Of course, they probably don't use qpsmtpd, so don't have the flexibility to fine-tune their rules so precisely... ;^) -- Tim
