Hello list, I'm with the CERT of the German NREN and am looking for a contact at megamailservers.eu on behalf of RWTH Aachen, one of our largest universities. I tried postmaster@ and abuse@ to no avail. Someone (knowing someone) from Vienna University pointed me to this list (thx :)).
# RWTH vs Megamailservers They can't seem to send or receive emails via megamailservers.eu, who are responsible for services to o2 users and former Alice users in Germany. When trying to telnet 'help' from RWTH's IP range they get ------------------------------- someone@rwth:~$ telnet mx1c52.megamailservers.eu 25 Trying 91.136.8.194... Connected to mx1c52.megamailservers.eu. Escape character is '^]'. 220 mail292c50.megamailservers.eu ESMTP Sendmail 8.14.9/8.13.1; Mon, 25 May 2020 12:05:42 +0000 help 550 5.7.1 H:MB[rwth-aachen.de]Connection refused due to abuse ^] telnet> c Connection closed. ------------------------------- from my private and company's IPs the telnet 'help' command succeeds. So it seems that their IP space is blocked at megamailservers. IPs of large universitites are often abused for shady things, so the (alleged) block of (some of) RWTH address space may have been in order at one point in time. But this thorough block goes on for some months now, so we are lookking for a personal contact at megamailservers.eu to sort out the issue. Someone from o2/Alice might help escalating the issue as well. Does anyone have a contact at megamailservers.eu / Alice / o2 Germany? martin -- Martin Waleczek (Incident Response Team) DFN-CERT Services GmbH https://www.dfn-cert.de/ +49 40 808077-555 Sitz/Register: Hamburg, AG Hamburg, HRB 88805, Ust-IdNr.: DE 232129737 Nagelsweg 41, 20097 Hamburg, Germany, CEO: Dr. Klaus-Peter Kossakowski
