Here is your problem:

corsica# nslookup main.wgaf.net
Server:  localhost
Address:  127.0.0.1

*** localhost can't find main.wgaf.net: Non-existent host/domain
corsica# 

There is no such internet hostname of main.wgaf.net

The remote machine tries to do a lookup on that address, finds that there
is no such host in DNS and refuses your email. Try using a valid domain.

corsica# mxlookup main.wgaf.net
main.wgaf.net does not exist (Authoritative answer)
wgaf.net does not exist (Authoritative answer)
corsica#
