#1 : In this scenario I’m creating a mail from firstname.lastname@example.org –TO–> email@example.com [domain set on DA box on its 2nd IP 126.96.36.199] (which also forwards to firstname.lastname@example.org [external mail] ]) and that forwarding ends with aforementioned bounced error message ( 188.8.131.52 is a main IP of DA box)
from domain dns administration
duan.pl. TXT "v=spf1 a mx ip4:184.108.40.206 ~all"
what is more
#2 users mails with Return-Receipt flag bounces to admin account on the box with [Delayed Bounce]?? Is that because of when /etc/virtual/limit_unknown reaches it’s max?
Any chances to help figure it out that bounce-mess 🙂 ? Big thanks in advance.
