I am receiving about 100s of spam emails in my webhost email (squirrelmail) So they fill up my hosting space withing 3-5 days and i have to spend lot of time deleting those mails.. I am also not able to limit the space for this mail id as its a default mail provided with webhosting.. Please help.. (i am also ready to give my cpanel to trusted DP member if he can help me)
If you have problem with mailbox space from spam e-mail then the solution for this is install some program to scan or filter e-mail before allow it come into your mailbox. The program that can handle this is SpamAssassin you can ask from you provider if they provide this application for you or not.
Firstly, don't give your cpanel to anyone. Secondly, to avoid this issue, never put your email address in an indexed page, because it can easily be harvested by spammers.
Most of the time, I would forward my domain emails to gmail and than forward it back to a secondary email though you still can reply it thru gmail if you want. Loving gmail filtering plus it wont affect your server load
