The DNS calls eventually time out and fail, but it takes a john, i saw the same thing when i moved from 4.1R to 4.3-BETA over the last week. sendmail by default is compiled with IPv6 support and this is what's causing the seemingly hang when it sends out email. ethereal confirmed that it was sending out IPv6 DNS queries and attempting to connect thru IPv6 before reverting back to IPv4. remove the "-DNETINET6" in /usr/src/usr.sbin/sendmail/Makefile and rebuild sendmail. works fine for me after that. --dinesh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
