I have Managed DigitalOcean hosting from CloudWays. I complaint to them that activation email is not sent from sign-up page of my site. First their reply was like noobdo Godaddy i.e. It is your script's problem. I challenged them to give their testing script. Even their testing script was not working.

Emails are not sent to recipient of gmail,hotmail & its other domains, yahoo.
In Zoho it arrives in Spam while I can see emails in temp-mail.org.
But gmail,hotmail and yahoo are not even allowing emails to spambox.
Now CloudWays is saying to use Gmail SMTP. Why the f**k I use GMAIL's smtp having 500 limits per day when I have virtual server with no limits to send.
