Hello,
I have an issue with a new installation of iRedMail. A client sends me messages from @hisdomain.eu, but I don't receive anything. And I can find nothing in the logs. If the message is sent to some Gmail account, it arrives properly and the header looks like this:

The postfix config is the one that came with the installer, except for the certificates path (using Letsencrypt).

What baffles me is that I can't find any trace of hisdomain.eu or amazonzes.com in the logs, so it's hard to trace and pinpoint the error.

Do you have any idea?

Any related log lines in Postfix log file (/var/log/maillog)?

Re: cannot receive mail from amazonses.com

Very similar issue on my server. Receiving mail from amazonses causes amavis to crash and I have to restart it. Mail from other domains arrives no problem. Same setup as OP minus I'm on Debian 11. For now I set the amavis service to automatically restart. I can see the emails in my log. When the amazonses server disconnects after the email is placed in the postfix queue, amavis crashes. Issue started January 17 in my timezone so same day as OP. What could be going on? My mail server is functioning totally normally and 0 changes have been made to it prior to this issue starting, no configuration changes or package upgrades. I received daily emails from an email using amazonses for 2 years with no issues before this started on Jan 17 in my timezone (EST).

I fixed it I commented out the .F and .zoo decoders in amavis' config file. Unsure why this happened, no packages besides older versions of the kernel have been removed anywhere near this issue beginning.

Re: cannot receive mail from amazonses.com

This is not a fix... amavis ignores encoders that are not found, so this didn't change anything at all, and you never had an encoder installed for this before, that is very common and not a bug


If a mail cant't be delivered, there is a bounce, and i am pretty sure you either have messed up a blacklist or anything else

Do you have any idea?

Could be DNS related, but first AmazonAWS IP Address's are on a lot of SPAM Filter databases, Here what I recommend doing first, check the domain.tld on mxtoolbox.com and verify that the domain is not on blacklists if so then will require contacting the Blacklist company to remove it. Issue with this is that it will most likely be flagged again.

How is DNS being handled to the SMTP Server ? are you using local DNS something like BIND9 or are you using Split-DNS ?

I would highly suggest running tail -f mail.log in CLI watch the log and send the mail from AWS see if it the logs mention anything about blacklists.

The DNS is handled by the ISP through CPanel, I can't really tell you more. Our domain is definitely not blacklisted and all checks on mxtoolbox are green.
I have no control over the client's mail server, these are automated messages that get sent when there is an order from them.
On my side, I've taken all the steps (I think) to whitelist the client's domain and amazonses' IP's.
Maybe this is something that has to do with the ISP?

Are you testing the Domain you are trying to receive mail from? or the domain you are using?

I'm testing both, actually.
