mail-address not accepted for registration

[HolgerKuehn]

Hi folks,

I've just switched to OPNsense, installed it this week, so far I'm quite happy, but come across a few questions I am going to ask here in separate threads. While registering I've tried to use my regular mail address, wich is from one major German ISP (@t-online.de), but the activation mail did never arrive.

Today I changed this to one address from my own domain, @dachs.blog, this one arrived instantly, as expected.
Any thoughts, why this might be?

Holger

Hi Holger, welcome to OPNsense!

It likely failed a spam/malware test somewhere. If you want to investigate further, take the SMTP header details from your successful email to dachs.blog (the 'Received: from' lines, particularly the last one) and open a support ticket with your ISP.

Deutsche Telekom tends to blacklist by default. Whitelisting involves a manual process. The person responsible for the website can contact me and I will happily share the details. Since the contact is not for end users I cannot post it here, sorry.

Holger, as a paying customer you might want to give Deciso a nudge so they contact me.

Kind regards
Patrick

Hi,

I've started a support request about this. Will keep you informed.
