I stopped receiving intervals.icu emails recently. I just dug into it, and my mail server’s logs and I found:

Jun  2 12:22:36 smtp postfix/smtpd[6954]: connect from f2.intervals.icu[162.55.20.108]
Jun  2 12:22:37 smtp postfix/smtpd[6954]: NOQUEUE: reject: RCPT from f2.intervals.icu[162.55.20.108]: 554 5.7.1 Service unavailable; Client host [162.55.20.108] blocked using zen.spamhaus.org; Listed by CSS, see https://check.spamhaus.org/query/ip/162.55.20.108; from=<messages@intervals.icu> to=<redacted@josefsipek.net> proto=ESMTP helo=<intervals.icu>

In other words, f2.intervals.icu’s IP address is listed by Spamhaus as generating spam and my server rejects email from those hosts. (This is a common configuration for mail servers to have.) The link in the 554 message has suggestions and steps to request removal of the IP from the block list.

(Grumble, the garbage we have to put up with because of spammers…)

Tx. Intervals.icu moved to new servers (with new IP addresses) recently and I have been chasing up quite a few of these.

Ouch. Been there, done that. I wish you best of luck!

P.S. FWIW, I received an email notifying me of your response here.

The forums run on the original Intervals.icu server which has a good IP reputation :slight_smile:

Anyway, in theory this one is fixed.

Removal successful.

Been unable to access it via WiFi provided by the by the largest distributor in Denmark, a friend of mine has the same problem. I guess this is connected to it? Any fix?

It is. I just got 3 emails as expected (a comment in the chat, a comment on an activity, and a coach checkmark). Thanks!

My report is about not being able to receive emails sent by intervals.icu. Is that your problem as well?
