Explanation of the error

This type of error is present when we're trying to connect to an incoming or -in this case- outgoing mail server but the server is taking longer than the timeout value to respond and send information. This could be due to a slow internet connection, for example, or if he host is offline.

We attempt to connect to the server for a given period (10000 msec by default) after which we disconnect (timeout) if the attempt is unsuccessful. This results in the Read timed out error quoted above.

Solution for the problem

A read timeout error can always be solved by simply increasing the timeout value configured for the corresponding mail connection.

Navigate to Email This Issue Administration - Outgoing Mail Connections and change the Timeout value to the maximum 60000 ms:

Outgoing Mail Connection Timeout setting

After this change, monitor your outgoing mails and reach out to your system administrator for help if this change in your settings does not help.
