@kapooht...Sorry but the getmxrr function should not be used for address verification. "This function should not be used for the purposes of address verification. Only the mailexchangers found in DNS are returned, however, according to » RFC 2821 when no mail exchangers are listed, hostname itself should be used as the only mail exchanger with a priority of 0." in http://php.net/manual/en/function.getmxrr.php

@Nils, No. The function just checks characters within the string. It allows only lowercase letters (a through z), numbers (0 through 9), fullstops before checking if an @ symbol is somewhere in the middle and if a fullstop is somewhere after the @ symbol, as well as checking if there are no more 4, no less than 2 characters after that fullstop.

Nice. getmxrr - would this slow down the script if I use a non-existing domain?
