Automessage PHP Errors

Hello,
Thanks in advance for your help. I recently switched from BlueHost to WP Engine. The AutoMessage plugin was working great with BH but not so much for me at WP Engine.

Here's an example of the error messages I'm receiving:

[client 24.27.67.0:19729] PHP Fatal error: Uncaught exception 'phpmailerException' with message 'Invalid address: noreply@https://community.citizensclimatelobby.org' in /nas/content/live/cclcommunity/wp-includes/class-phpmailer.php:946\nStack trace:\n#0 /nas/content/live/cclcommunity/wp-includes/pluggable.php(352): PHPMailer->setFrom('noreply@https:disappointed:...', 'CCL Community', false)\n#1 /nas/content/live/cclcommunity/wp-content/plugins/automessage/classes/class.user.php(103): wp_mail('maanasa.koduru@...', 'Connect with yo...', 'Howdy saikoduru...', 'From: "CCL Comm...')\n#2 /nas/content/live/cclcommunity/wp-content/plugins/automessage/classes/class.automessage.php(1599): Auto_User->send_message('Connect with yo...', 'Howdy %username...')\n#3 /nas/content/live/cclcommunity/wp-content/plugins/automessage/classes/class.automessage.php(411): automessage->force_process_user('3111')\n#4 /nas/content/live/cclcommunity/wp-content/plugins/automessage/classes/class.automessage.php(325): automessage->process_admin_updates()\n#5 [internal function]: automessage->add_admin_h in /nas/content/live/cclcommunity/wp-includes/class-phpmailer.php on line 946

Not sure why the email address is showing noreply@https://domainname instead of noreply@domainname and the automessage errors.

Thanks for taking a look at this for me.
