POP Logi Error

I setup VirtualMin/WebMin and can login to the webmail interface, but when I try to login to the POP3 server I receive the following error. Dovecot IMAP/POP3 Server is installed and started.

Receiving’ reported error (0x800CCC92) : ‘Your e-mail server rejected your login. Verify your user name and password in your account properties. Under Tools, click E-mail accounts. The server responded: -ERR Plaintext authentication disallowed on non-secure connections.’

Any help would be greatly appreciated.


Hey John,

Well, first off, I bet if you accessed using POPS or IMAPS (which encrypts your connection), it’d probably work – though I know that’s not always an option :wink:

The other thing is that there’s a Dovecot option you may need to set. If you edit /etc/dovecot/dovecot.conf, search for “disable_plaintext_auth” and make sure it looks like the following:

disable_plaintext_auth = no

I believe it’s “yes” by default.

I’m certain you could do that within Virtualmin as well as from the command line, though I don’t know where in Virtualmin to tell you to go :wink:

Thanks Eric! The change to dovecot.conf worked.
