I’ve managed to get 2 of my precious IP’s blacklisted in spamhouse during email testing… All because postfix was sending HELO “server.example.com” … Well done !
Platform: VPS, CentOS 7.6 (4GB RAM 4x86x) CyberPanel 2.0
Fresh install (selinux=disabled)
-
Postfix bug:
config not configured properly on install. (myhostname not set, maybe something else too?, but servers FQDN was set from the start), outcome: sent emails rejected and IP blacklisted.
-hotfix: setup postfix config manually
-
Dkim bug:
log error: “opendkim is in group ** which has multiple users…”. outcome: server can’t send emails.
-hotfix: append RequireSafeKeys false to /etc/opendkim.conf
Im really happy for you. But Im using my time to report CP’s bugs here. As a VPS hosting expert you shouldn’t present your single example as a result for CP’s reliability.
I have a fresh install, I followed Cyberpanel guide, no selinux, no firewall was present during the install. I still have 2 different VPS’s With CentOS 7.4 and 7.6 that have the same issues. I didnt test them at the very beginning after install, so maybe it is a configuration conflict of firewall etc, but anyway all setup was done within CyberPanel.
atm I have a few issues with mail like unable to login to inbox from external apps like Outlook, etc…
I use Scaleway - DEV VPS, CentOS 7.6.
What logs / configs should I list here?
