I'm aware that gmx.net primarily serves Germany, Austria, and
Switzerland, while gmx.com is intended for global users. However, I've
encountered an unusual issue with both domains. When sending emails from
certain regions (like my current location in Singapore), regardless of
whether I use gmx.net or gmx.com, the messages are routed through a
separate gateway. Unfortunately, this gateway's IP address is heavily
compromised and listed on the Spamhaus blacklist.
Interestingly, this problem doesn't occur when using GMX services from
European locations. In those cases, outgoing emails are sent through
normal, clean gateway IPs.
I've attached a bounce message from one of my emails below, which was
rejected due to the Spamhaus listing. This raises a question: Isn't
GMX's approach to spam prevention for non-European regions overly
simplistic and potentially harmful to legitimate users?
SMTP error from remote server for RCPT TO command, host: mx.sample.com
(20.xx.xx.xx) reason: 554 5.7.1 Service unavailable; Client host
[82.165.159.13] blocked using z
en.spamhaus.org; Listed by SBL, see https://check.spamhaus.org/sbl/que
ry/SBL594401
Does anyone else think that GMX's anti-spam measures for outgoing emails
from outside Europe are a bit too blunt and potentially
counterproductive?
Thank you.
