How to check the id is main or alias

[Oreo]

add both ID's and see if they come on at the same time. Or you can look at the profile on the website to see if it's active at the sametime and goes off at the same time. Don't be sorry for posting here....just be clear with your intentions.....that way your questions can be answered more easily and correctly. You are not malicious people, but there are plenty out there.

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?

Alias IDs can receive e-mails too if you have the secondary e-mail activated and set up for it.

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.

ooh.. i forgot.. the domain not always @yahoo.com rite? it can be yahoo.co.uk, or else country... sigh...

Main IDs, and a secondary mail alias ID can get mail at the same time. There are ways to find out weither or not an ID is a main ID or alias ID, but those ways can violate a person's privacy, hence why I won't mention them here.
