Hi,
There are no breaches or spam or anything sent from that server. I
would know as I am part of the AS6772 Abuse Desk. :-) Just the
dozed or so emails per day sent by my family members and myself.
Even emails to my own Gmail Account where my sending email address for
sure is a know past sender, are being blocked.
we had a similar issue after moving mail.ffnw.de to a new server / IP,
though the mails are DKIM signed and SPF passes:
<[email protected]>: host aspmx.l.google.com[2a00:1450:400c:c0c::1b] said:
550-5.7.1 [2a03:4000:47:88::1] Our system has detected that this
message 550-5.7.1 is likely suspicious due to the very low
reputation of
the sending IP 550-5.7.1 address. To best protect our users from
spam, the
message has been 550-5.7.1 blocked. Please visit 550 5.7.1
https://support.google.com/mail/answer/188131 for more information.
h13si190255wmb.87 - gsmtp (in reply to end of DATA command)
I remember a discussion here that reputation is somehow bound to a
domain with DKIM, SPF, etc, but this seems to be irrelevant in this
case, or do I miss something?
Best Regards
Bjoern
