Random Email aliases

i need to create random/pseudo email address that will be delivered to a real email address.

Each of my registered client will have a unique & standard pseudo address to send there some specific formated emails. Example

• david121238732bnash@mydomain.com
• nick32478234234723923@mydomain.com
• ........maybe hundreds ............

Because the number of clients is big I can't manually add so many addresses. I need something dynamic.

All emails will be delivered to info@mydomain.com . Each email will be fetched with PHP, so probably I need IMAP access (cpanel,gmail)

How I can archive it? Example with random email here http://ift.tt/10GLh1C

I use cpanel.
