Hello,
after updating postfix I can’t receive any emails from outside like gmail or outlook …etc
how I can reset postfix configuration to default or fix it?

the mail.log message:

Oct 5 18:47:48 ns1 postfix/smtpd[87528]: NOQUEUE: reject: RCPT from mail2.odoo.com[149.202.180.44]: 451 4.3.5 <odoo@mydomain.com>: Recipient address rejected: Server configuration problem; from=<bounce+102343518-event.registration-675570@mail.odoo.com> to=<odoo@mydomain.com> proto=ESMTP helo=<mail2.odoo.com>

I would temporarily increase the verbosity of logging and tail -fn 200 mail.log while watching an incoming email transaction. Also restart Postfix from the commandline or Web UI and watch the logs. You can also specify a custom maillog path.

Did you just run apt-get upgrade and have you added any third-party repositories? Have you altered your postfix config files, or imported lots of settings which used to work in an older Postfix version? If you have jumped many versions with the upgrade then you may find some of the config variables are deprecated with the new version of Postfix.

Posting your main.cf and master.cf (or postconf -n) may be helpful.

You’re running Postfix 3 and on my CentOS systems I’ve not moved off the main EPEL repositories so I’m still on 2.10. However, the configs are mostly the same.

A few queries -

NB - if you use geoip-based checking in Postgrey, or any other software which invokes the GeoLite GeoIP.dat database, MaxMind now require an API key and account for using geoipupdate, and to download the actual GeoLite2 databases. https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?lang=en

very very very thanks, the problem is resolved after deleting check_policy_service inet:127.0.0.1:10023 from the smtpd_recipient_restrictions

That’s great news. However, that will be required if you want to use Postgrey for greylisting, so bear that in mind. :slight_smile: Keep a backup of your previous config just in case, I always do!

Did you copy the configs from a tutorial or are they from your original installation?
