ooh.. i forgot.. the domain not always @yahoo.com rite? it can be yahoo.co.uk, or else country… sigh…
So we can say that if the id cannot receive email, it must be an alias. If it can, we don’t know whether it is main or alias id. Can we assume like that? Is there any other way to check whether an email address is valid email address, without sending email? I have tried once on web, it said that the email address is valid, but when i tried sending to that address, it failed.
how if we check by send an email to the someoneID@yahoo.com. can we assume that the main id always can receive email, the aliases cannot? if the mailerdemon email you, then the id is alias? if it successly sent then it is main id?
