Victor, Thanks, that reasoning makes sense. Still it was quite irritating that a Postfix upgrade "broke" my system (quoted because it didn't break but suffered from a resolver bug that Wieste probably hadn't seen on FreeBSD), this hadn't happened in a dozen years. I had checked the Postfix 2.8 release notes immediately, but they bore no references to this particular HISTORY entry: 20100827 ... Bugfix: the Postfix SMTP client no longer appends the local domain when looking up a DNS name without ".". Specify "smtp_dns_resolver_options = res_defnames" to get the old behavior, which can produce unexpected results. Files: smtp/smtp.c, smtp/smtp_params.c, smtp/smtp_addr.c. Can this retroactively be put into the 2.8 release notes as [Incompatible Bugfix ...] entry on the websites and for 2.8.3+ releases? Best regards, Matthias
