Cpanel update causes Squirrelmail problems!

This is the second time this has happenned.

I get an email (forwarded to me by my provider) from Cpanel, saying that they have discovered security issues with Horde webmail, and we are advised to update our cpanel versions.  I do so on all my servers.

Next thing I know (sometime later usually) is that I am unable to send emails using Squirrelmail and Horde.  This is the error message:

"Server replied: 111 Can't open SMTP stream. "

Turns out the problem is with a setting that gets over-written during each cpanel update:

To fix the issue, do the following:

SSH to the server.

Edit the squirrelmail config file, config.php, located here:

/usr/local/cpanel/base/3rdparty/squirrelmail/config/config.php

Around line 33, change

useSendmail = false;

to

useSendmail = true;

Save and exit the file, no need to restart anything, squirrelmail starts to work immediately.
