need to setup a complex email catchall
we are building a service wherein anybody can add our domain to recipients ids to enable tracking...and security as to who is viewing the mail.
for eg. actual TO: email@example.com
new TO: firstname.lastname@example.orgDOMAIN.COM
the mail server has to catch email@example.comDOMAIN.com, and forward it to process@ourDOMAIN.com
we have been trying to tweak our server's dns to do this, but it repeatedly only works if we create subdomains like "yahoo.com"... we want it to catch any subdomain.
any help is appreciated.
