Virtualmin -- An error occurred listing mail in this folder : Failed to login to POP3 server : Internal error occurred.

Hi

I am getting an error on one of my servers when I use usermin to access specific users email account:

An error occurred listing mail in this folder : Failed to login to POP3 server : Internal error occurred. Refer to server log for more information.

I have tried this several times and I find nothing in the logs that reflects an error.

I can read the email through webmin > servers > read user mail

I am getting this on all user email accounts.

Any ideas?

Peter (tpnsolutions) was able to assist me with this issue tonight. It was related to dovecot and its “first_valid_uid” of "1000 setting in my version. Set it to “500” and it’s working perfectly. Thank you to Peter. Your help is much appreciated as usual.
