Package: nullmailer
Version: 1:1.00-2
Severity: wishlist
Tags: patch
Hi,
There is no support for IPv6 support in nullmailer, which is a shame and
so I rolled out the attached patch.
I actually sent this first to the upstream author but never received a
reply :( Instead I thought I might aswell send it to the Debian
maintainer :)
I feel my patch is cleaner than the one recently posted on the
nullmailer mailing list (beat me to the patch by two weeks :)
http://lists.untroubled.org/?list=nullmailercmd=showmsgmsgnum=548
Which ever patch is chosen, one needs to go in...fight to the death? :)
Cheers
