Fix mail settings
It looks like your mail servers is misconfigured, which causes my mail server to reject all emails coming from noreply@onionwatch.email (via onionwatch.onionwatch.email
= 185.104.122.73
) with 450 4.7.25 Client host rejected: cannot find your hostname
Please setup your mail server and DNS properly, including:
- Set an MX DNS record for the name you're using in the
helo
line (helo=<onionwatch.onionwatch.email>
) - Set an rDNS / PTR record for the IP that points back a the above-listed DNS entry.
I'm far from a mail server expert, but I see no MX record
