just a heads up, perl 5.10.1, freebsd 7.3, i386 code, mearly HAVING

IO-Socket-INET6

caused major delays (1 hour per email).

removing it fixed it.

testing was done with 'spamassassin -D < {email}', and it hung, 
complaining about 'no ipv6' on EVERY dns query.

also note, freebsd 7.3 amd64, didn't have any problems.

tried 'p5-IO-Socket-INET6-2.61' to 'p5-IO-Socket-INET6-2.65', BOTH had 
problems.

freebsd 7.3, compiled without ipv6.
host -6 -t txt S1024._DOMAINKEY.YAHOO.COM 192.168.140.29
host: can't find IPv6 networking

this fixed it:
deinstalled p5-IO-Socket-INET6 and everything is fine.
