Re: [xmail] ERDNS weirdness
I´m using W2K SP4 + Xmail here for years, without problems... The first version of nettest (that was sended in 09/05/2009) didn´t run here. The second version (that was sended in 09/07/2009) ran without problems.

Re: [xmail] ERDNS weirdness
HI Davide,
So am I correct that all the RDNS check does is look for a hostname and
that's all? Or does it compare it to something once it gets it?
Davide can you, or anyone else on this list e-mail an exe of the test
program so I can see if it works on the Windows 2000 server that xmail
is on?
Thanks,
Bill

XMail does simply a SysGetHostByAddr() when doing an RDNS check, and this
translates to a call to getnameinfo(), on both Windows and Unix.
It works fine on Linux (using the test program below), and it should even
on Windows:
$ gcc -o nettest nettest.c
$ ./nettest 207.162.214.242
name = 'mx.soldoutdisciples.com'
