Hello I did everything but my incoming emails are not received by default email and I get the following error. Fix cPanel LMTP error after RCPT TO

However, I examined this issue according to the following link, but I did not get any results

How to diagnose "550 5.1.1 User doesn't exist" with forwarder

Can you help me solve this problem? Is it related to updates or ... cpanel? Thank

The thread you referenced would suggest that this issue is born about when an account isn't removed properly.
Is this the case ??

I found this thread LMTP error after RCPT TO 550 5.1.1 user doesn’t exist

Also found this on another forum.

If you are suddenly getting "LMTP error after RCPT TO" error message when users send emails to your forwarded email address, then verify that the forwarded email address was not created at some point in time and then deleted as POP3/IMAP box.

Do that by deleting the entry at /home/$username/mail/$domainname.com/Usermailbox

For example, if the issue was with [email protected] , then delete the entry:

/home/$username/mail/somedomain.com/support

Only do this if you're using forwarder only, and there is no mailbox exist for that user.

Hello We have reviewed the cases you mentioned many times, but no results have been obtained We removed the default email user but the problem still persists

According to reviews, this problem does not exist on older versions of C-Panel As: V 90.0.3 And V 86.0.25 Does anyone have any information to fix this problem from version V92.0.3?

have you tried temporarily creating the account to see what happens.
Yes There is no problem if I create any new email account on one host But this is only a problem if we want to redirect emails with the wrong email address to the default email. Which gives the LMTP error.

This problem has not been resolved yet And this problem is definitely on the new version of C-Panel because I have the same problem on several servers with the latest version of C-Panel !!
