The recent question reminds me - since leaving for another VPS provider,
the various VPSes have had various difficulties with getting emails from
them accepted by the dominant Google / Microsoft / Yahoo services.
In one case, the content - requested activity alerts from a message board -
hasn't changed, and the volume is way *way* under anything suspiciously
spambot-y - a hundred emails a week, not per second - but Microsoft have
simply refused to accept email to users that have Hotmail / Outlook
accounts, despite the only significant change being the IP address it comes
This is even after jumping through all of the hoops in the sometimes very
outdated Microsoft 'help' (sic) pages: I strongly suspect that they are
blocking the new provider's whole IP address space (or nearly so...)
Despite having various filters set up to say 'no, it's not spam, how many
times do I have to tell you', Gmail still keeps wanting to label fail2ban,
logwatch, and other system report emails as spam.
I look at
and go 'at least it isn't just me' and 'I hope someone takes the oligarchs
to someone with teeth', but before I lose all my hair..
.. can you still get emails delivered from Bitfolk VPSes to the three
reliably to inboxes?
Gmail is bouncing emails sent by sendmail. The from address is
name@mydomain and I've set up an SPF DNS record for mydomain which looks
v=spf1 a a:aremiti36.vps.bitfolk.com ip6:2001:ba8:1f1:f09e::2 ~all
the domain and https://www.dmarcanalyzer.com/spf/checker finds it OK
but i'm still getting emails bounced:
SMTP error from remote mail server after end of data:
host gmail-smtp-in.l.google.com [2a00:1450:400c:c06::1a]:
550-5.7.26 This message does not pass authentication checks (SPF and
550-5.7.26 do not pass). SPF check for [aremiti36.vps.bitfolk.com] does
550-5.7.26 pass with ip: [2001:ba8:1f1:f09e::2].To best protect our
550-5.7.26 spam, the message has been blocked. Please visit
name@mydomain is redirected to kit.wallace(a)gmail.com so I'm not sure gmail
is even looking at mydomain's DNS record anyway
Basically I don't know what I'm doing and in need help!
My VPS is on Debian 11. I cannot get firewalld to work. For example when
I stop firewalld by
systemctl stop firewalld
I would expect that I no longer can ssh into my VPS but I still can.
Does anyone know how to tell the system to use firewalld?
