Hello again,

I updated Dovecot according to the instructions on the links that you sent, and can now restart the Dovecot service without erros.

However, this didn't solve the issue that none of my users are able to send any email.  The system receives, and filters incoming messages fine.  Whenever anyone tries to send a message out they get the same authentication error every time.

I know I've probably missed something in the configuration, but I have to admit that I'm completely lost at this point.

I've attached the latest log entry below, and moved the conversation to the forum, as requested.

Thank you for all the support,
Jim

oh, you upgraded Dovecot from 1.x to 2.x, and old config file is not compatible. You have to follow Dovecot tutorial to update your config

Dovecot was running.  I  tried restarting it twice, but I received some errors both times.  I've attached a copy of the error output.

Thank you for the quick response, by the way.

Hello,

I am having an issue getting my mail server to send out any messages.  Whenever any of my users try to send an email they get an pop-up error from Roundcube.  When I check the logs, I see that it is an error related to authentication.  (Both the pop-up, and log messages are attached.)
