I have been perfectly happy running randomstring.org (at home) and $WORKPLACE's mail servers with none of DMARC, SPF or DKIM for years and years now. There was a short period of time where aol.com and yahoo.com didn't want to accept mail from me directly. That time went away some years ago. -dsr- _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
