"Greeting never received" when try to send email

[medzhidov]

Describe the bug

If I send about one message per second, there is no problem. However, when there are more than 10-20 messages in the queue and I send about 3-4 messages per second, I get this error. I don’t experience the same error when sending a lot more messages per second in Yandex Postbox, so the problem is somewhere in the postal server.

Expected behaviour

No problem with connection)

Screenshots

Additional information/context

We tried increasing the number of workers to 8, but it didn’t help us.

Can you share a screenshot of one of the affected messages in the Postal UI? There would be extra information on the right hand side.

@willpower232 postal reject them before they come inside 😢 Now we switched to yandex postbox and want return to postal but we don't know what to do with this error(

[willpower232]

If you can't see any more information then you will need to use postal logs smtp to see what is actually happening and what error message is being returned to whatever you're using to send the emails.

postal logs smtp

You run the command outside of the docker container. There should not be a need to execute any commands inside of the container.

Loot at the second line of screenshot please. This command executed inside docker container with smtp server inside it

Outside of container you can see the list of all containers in the server.

But inside container there is no any subcontainer:
