My hosting provider informed me that, there are lots of spam emails going from my server,
this message i got from server support when my out going email were blocked.
As most of those mails were blocked as confirmed spam by our spam filter, out going email service of supremeengg.com was suspended on 2014-11-14. Due to which you might had issues while sending mails from this domain. Check the detailed log report given below:
99% of the email shown there are not created by me and it seems they are spam email ids formed by bots or malware.
can anyone guide me how to prevent any malware use our email id and how to stop spamming.
