My concern is that I was sending to Gmail recipients perfectly well through the old server using exim4, then about four days later when I got Postfix running on new hardware using an equally self-signed certificate, it wasn't working. There was no change to the domain credentials, which are just SPF. It may be that Google got more picky in that four days, but I was hoping it was some simple misconfiguration of Postfix. with which I have no previous experience. Maybe not. -- Joe _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
