could this be system clock after updating the ubuntu kernel?

yes it was an hour behind

Right, the test email i sent bounced back with the same error, which is clear in .\launcher logs mail-receiver

okay so both the mail-receiver container and app container are set to a different time to the host system

host system - correct time :white_check_mark:

app container - wrong time :cross_mark:

well it’s still different, after rebuilding mail-receiver and causing both - to go yellow

these were the last emails to get in

they appears set to a different time zone, which is fine.

Assuming you ran these commands a couple minutes apart, this looks good.

It’s impossible to tell from these screenshots what exactly is happening.

What is the inbound address for your forum? (slightly redacted if possible)

What address is it coming from?

What’s happening with mail sent to it?

Please use text of your logs rather than screenshots.

discourse.domain.com

it’s connects to mail-receiver but mail-receiver sees the IP as unknown, so bounces it back, the email doesn’t land in the mail-receiver’s queue.

I don’t believe this is correct. It’s a warning, not an error.

This screenshot (please make this text) indicates the address ppyem30@discourse.domain.com is not accepted - that appears to be the reason for the failure.

I’d look more into the using backwards-compatible default setting… line, that seems to be hinting towards the reason.

i tried ask.discourse.com

21

I have followed the steps. One thing that needed clarifying was when i get to the /var/discourse/shared/mail-receiver/ directory,

should i have written

nano valid_recipients

or

nano valid_recipients.yml.

It was a copy+paste job in mail-reciever.yml and then another rebuild, corresponding to the below logs

I have custom incoming email addresses for many categories. Does the format need to change to category+<tag>@discourse.DOMAINNAME.com (for direct posting to a category)?
