# Troubleshooting Email Errors
|
|
|
|
Email communication is crucial for any organization, but issues can arise that disrupt this essential service. This guide provides practical steps to diagnose and resolve common email errors encountered in [OpenPanel Enterprise edition](/product/openpanel-premium-control-panel/), ensuring your email systems run smoothly and efficiently.

|
|
## ERROR list mail user: '/tmp/docker-mailserver/postfix-accounts.cf' does not exist
|
|
|
|
Dovecot is not started until the first email account is created, therefor listing email accounts with the command `opencli email-setup email list` before creating any email accounts, will produce error:
|
|
```bash
|
|
root@stefi:/usr/local/mail/openmail# opencli email-setup email list
|
|
2024-08-27 07:55:15+00:00 ERROR listmailuser: '/tmp/docker-mailserver/postfix-accounts.cf' does not exist
|
|
2024-08-27 07:55:15+00:00 ERROR listmailuser: Aborting
|
|
```
|
|
|
|
**Solution**: Create an email account first with [opencli email-setup email add](https://dev.openpanel.com/cli/email.html#Create-email).

## Error: auth-master: userdb lookup(user@example.net): connect(/run/dovecot/auth-userdb) failed: No such file or directory
|
|
|
|
Immediately after creating first email account, dovecot is still creating necessary files in the background, so running the `opencli email-setup email list` immediately after creating first email account will produce an error:
|
|
|
|
```
|
|
root@stefi:/usr/local/mail/openmail# opencli email-setup email list
|
|
doveadm(stefan@stefi.openpanel.site)<577><>: Error: auth-master: userdb lookup(stefan@stefi.openpanel.site): connect(/run/dovecot/auth-userdb) failed: No such file or directory
|
|
doveadm(stefan@stefi.openpanel.site): Error: User lookup failed: Internal error occurred. Refer to server log for more information.
