Email ids under 1 user not receiving emails

All was working fine

Suddenly all email ids under a user stopped recieving emails (Has multiple domains)

I checked for quota, increased quota. No use

The folder permissions under var/vmail/domainname has

user | mail | 751

maillog do not have the record of missing incoming emails

Please guide

And you tried suspending, then un-suspending the account?

Tried after seeing your message

No luck

And you tried suspending, then un-suspending the account?

Code: [Select]

chown -R vmail:mail /var/mail
chmod -R 755 /var/vmail

Code: [Select]

chown -R vmail:mail /var/mail
chmod -R 755 /var/vmail

Now getting the bellow errors for all webmail logins

Connection to storage server failed.
Server Error: AUTHENTICATE PLAIN: Authentication failed.

The storage server is IMAP (dovecot), so not being able to access. Try 770 permissions (which is what one CWP server has; oddly, the other one is 755 which came from a cPanel import):

Code: [Select]

chmod -R 770 /var/vmail
chown -R vmail:mail /var/vmail
