@Nikolas were you able to get the logs? we’re still unable to check emails
logs have been successfully received.
I will notify you as soon as there is a result.
@rodster
Please specify, do you have users added via LDAP?
@Nikolas apologies for missing that detail. Yes, all users are authenticated via LDAP (except for the main admin user)
@rodster
Yes, it was important 
For some reason, I didn’t think to clarify this detail myself.
We managed to reproduce the issue on our side and we are trying to detect and fix the root cause.
I will inform you additionally about the result.

I’d like to possibly reopen this. Same thing happened to me except restarting the docker containers did fix the problem for me. However, this is the 2nd or 3rd time this has happened.
I’m not positive but this error may have something to do with it:

I’m also using Docker but unlike OP, my users are not authenticating through LDAP. Mine are just using the local auth.
Hello @austin3410
This is really old thread, the mentioned bug was fixed. Let’s start from scratch.
Please confirm that you faced exact issue as topicstarter:
send email to a recipient, then recipient checks the email via onlyoffice web, the email is not there. but if checking via imap, the email is there.
If so, please let us know your Workspace components versions (you can check it in the Control Panel) > reproduce the issue one more time and record a video file > collect entire logs folders (Mail server and Community server logs).
Sorry for the delay, unfortunately this issue happens randomly and I can’t knowingly trigger the issue. I agree this thread is incredibly old, if you’d rather, I can just start a new thread with this info the next time I notice the issue.
Austin
Hello @austin3410
Yes, please try to reproduce the issue and start a new thread. We will check it out.
