such error is not related in any way with any Akeeba products: if you uninstall every plugin you'll see that the problem still occurs.
For what is worth, I'm currently using WP Mail SMTP with Akeeba Backup and Admin Tools in my development sites and everything is working fine, you should review your email settings.
