You can do a lookup on the domain name to make sure it is a valid domain (use gethostbyname() for example).

Ths can be a lengthy operation depending on how good your access to the names server is.
I faced a similar problem before and tried looking up host name,etc but it turned out to be too wasteful. Instead I just checked for the following pattern xxxxx@xxxx.tld where tld was a from a list of common top level domains that i statically declared.

Hi,
If you want to check the format of Emai l address use:

char Address_String[], Name[], Domain[], Ext[];
sscanf(Address_String, "%s@%s.%s", Name, Domain, Ext);

and check each field to validate it.

If you want to find, if it is a valid Email, KurtVon has stated it.

Good Luck!
