[BWG-823] LMTP 451 4.3.0 Temporary Internal Error on KVM
T=dovecot_virtual_delivery defer (-44): LMTP error after RCPT TO:: 451 4.3.0 Temporary internal error
please how can i fix this issuee, this problem started after cpanel update to v80.0.18
i never had issue with mail my other servers, one of my server is experiencing this issue now. since i update to cpanel vv80.0.18
Hi @shaun, Can you access one of the affected servers and look at the /etc/fstab file to see if the root filesystem (e.g. "/") is associated with a device that doesn't exist? For instance, many of the affected systems we've seen have an entry like this in their /etc/fstab file despite /dev/simfs not existing as a device:/dev/simfs / reiserfs rw,usrquota,grpquota 0 0
Here's a command you can use to help identify if an invalid device name is utilized:diff -u /etc/mtab /proc/mounts
Thank you.

Hello Everyone, I've marked this thread as SOLVED with cPanel & WHM version 80 now in the RELEASE build tier. Let us know if any additional issues are noticed after upgrading to version 80. Thank you.

Hello @victortin, Can you search /var/log/exim_mainlog for an email address affected by this issue and post the output here? Here's an example of a command to search the Exim log: exigrep user@domain.tld /var/log/exim_mainlog
Replace "user@domain.tld" with the email address of an affected user and let us know the output logged for one of the email transactions associated with the reported error message. Ensure to paste the output in CODE tags and replace real domains and IP addresses with examples. Thank you.0 -

Hello @victortin, When i can chage the package to unlimited mail will be delivered.
Are you sure the individual email account, or the cPanel account itself, is not at it's disk quota limit?Thank you for your response, if you want me to send root details i will gladly do that, i just want this issue to resolve.
We don't request or accept login credentials on the cPanel Forums as a security precaution but you're welcome to submit a0 -
Hello @victortin, Are you sure the individual email account, or the cPanel account itself, is not at it's disk quota limit .
No is not a disk quota limit with the account or cpanel we have available space 37% on the system, i will go ahead and submit ticket.0 -
The issue has been resolve by temporary workaround from cpanel support i await for update. see solution below. took the liberty of applying the temporary workaround by running these commands: # cp -av /var/cpanel/templates/dovecot2.3/main.{default,local} # sed -i '/^lmtp_rcpt_check_quota =/{s/yes/no/}' /var/cpanel/templates/dovecot2.3/main.local # /scripts/builddovecotconf # /scripts/restartsrv_dovecot Your server is now able to receive email without issue: 0 -
Hello @victortin, Thank you for sharing the temporary workaround. Here's the link to the thread where the cause of this issue is discussed: It's important to note that case CPANEL-26002 does not address the issue for servers operating under the KVM environment. A separate case (BWG-823) is open KVM servers. I'll monitor this case and update this thread with more information as it becomes available. Thank you. 0
