e-mail processes slowly in the cowmail structure.

clauferhferreira

Good afternoon.
I would like some help if possible.
I have a cowmail environment in docker and some domains configured in this structure. In a specific email, I’m having problems with receiving. The employee receives an e-mail that contains a code, valid for five minutes.

The e-mail is triggered and I see it arrive on the server, with the rspamd log, but it takes seven minutes to enter the person’s inbox, making it impossible to log in with the code. The infrastructure team has already checked the internal infrastructure, made sure it has space available in the Inbox, and restarted the containers. Nothing worked.

Can anyone help?

Can you have whoever is managing your mailcow server reach out with the relevant information/issue?

It’s because of greylisting

DocFraggle How can I adjust it so that it doesn’t only check emails from one domain? I added some to the spam filter configuration, but it didn’t work.

DocFraggle

You could try to add the domain at the “Header-From: Whitelist”. You can find it at System -> Configuration -> Global filter maps

Select the checkbox to see the “Header-From: Whitelist” text box

You can enter a domain like this:

/.+example\.com/i

DocFraggle Okay, I’ve applied the configuration.
Do I need to wait to test or restart any of the mailcow containers?
