mantis mail notifications comes (at least the ones i have downloaded in the past) from 2 SMTPs

202.142.142.238 mx3.wide.net.au
202.142.142.239 mx4.wide.net.au

the 2nd is blacklisted on sorbs
just for information (even if i don't use spam.dnsbl.sorbs.net )

i'm probably one of the most expert MTA admins still around
nowadays in Italy, even if that is an endangered profession,
from stuff like simple MTAs to Exchange

of course i know spam filters products and various firewalls

i don't understand why you keep offending me on public MLs

e.g.
"More from the multi-verse."
"As someone that who gets paid to supply mail services to clients"

this thing is extremely annoying
