Test SMTP Connection and cron inspection SMTP
Whould be nice if we had a future to test SMTP connection like when we test add server. I have create a print to show how.
And also this should be inspected by a cron, so if we for some reason change our email passord and we forgot to update it on WHMCS we could miss new emails until we realized that something is going wrong.
This future would be a must for everyone and also get WHMCS better.
