Hello Folks,

I am confused. One of my client is using spam filter (MX Thunder) and email routing is set to "Local Mail Exchanger" and user is getting too much spam emails. If I change

email routing from "Local Mail Exchanger" to "Remote Mail Exchanger", will there be any issue?

Awaiting for swift response.

Note: The A record of mail is pointing to our server.

Thanks,

Pratik Jajal

Pratik,

You need to have it set to local. SpamHero should have given you several MX records, make sure to remove any old MX records and only use the new ones they provided. DNS changes are not instant so you will have to wait a good 2 - 3 days for all mail to start flowing through SpamHero.

Here is the first hit on Google when searching for "spamhero cpanel"

spamhero.com/support/78716/Configuring_cPanel_with_SpamHero

Keep in mind, its possible spammers may cache your mail server which allows them to still bypass SpamHero:

Hi,

I have gone through the links which you have provided but there is no exact steps mentioned which I can follow to prevent this issue.

Is there anything else solution other than this one?

Thanks,

Your telling me you implemented the filter into cPanel and it didn't stop the emails? If you did properly implement the filter, that means the emails are going through SpamHero and are not being filtered in which case you would need to contact them.

Shared Hosting Providers Using cPanel

If your hosting provider is using cPanel, the most effective thing you can do is create a cPanel filter to block emails that do not contain X-MXTHUNDER in the header. For detailed instructions on how to accomplish this, see the following article: spamhero.com/support/125578/article Create cPanel Filter to Stop Spammers From Bypassing SpamHero

Hi,

I have followed your provided link "spamhero.com/support/125578/article" but all genuine emails are moving to the specified folders so this solution does not work for me.

Please guide me further.

Thanks,

Sorry I don't understand, what do you mean by "are moving to the specified folders"

Hello,

Changing that option will not increase or decrease the amount of SPAM delivered to the email address. If the SPAM filter is not blocking enough SPAM, then you'd want to check with the remote service you are using for to prevent SPAM to see if they can alter any settings on their server. Otherwise, you could stop using that service and consider enabling options in cPanel & WHM that will help prevent SPAM (E.g. Greylisting, RBL checking, SpamAssassin).

Thank you.
