Re: Trying to get sendmail-8.15.1 from pkgsrc working on NetBSD-5, libresolv issues

} This has the side effect of causing everything built with pkgsrc

sendmail has not messed with the _res structure since sendmail
8.14.9 was imported almost four years. There is an exception to
this general rule when using SASL as there is some kind of weird
problem that happens when SASL, NAMED_RESN (pkgsrc specific) and
MILTER are all defined.
However, you missed option 3, which is to upgrade to a supported
version of NetBSD. Seriously, if this box is facing the Internet, then
running NetBSD 5 is extremely unwise.
