spam filtering
For adding spam filter you should allow regex type as spammers keep adding subdomain. For example I get spam from ********* ,****.
The spammer impersonates as Amazon and keeps adding app subdomain. To counter this I should be able to add filter like "^<star>.****". or ".<star>instantupdates4u.com" or "<star>@<star>.instantupdates4u.com". Gmail allows regex filtering.
The post removes global character star. I have substituted the star character with <star>.
