[dba-Tech] Validating Email Addresses

Hi Rocky

In that case I would just send them a friendly notice, that you still hold the address on your list. You could even offer the receiver to be taken off should he/she wish to.

Gustav:

I'm really looking to cull the old addresses from my address book where the
address is truly dead.  Not too concerned about spam filters.  These are all
addresses I've sent stuff to before and gotten through. 

I guess a 'test' email to the whole list is the best way.

Hi Rocky

Not really. 
Some spam filters accept all mail to learn from it, only forwarding (of
course) those e-mails not detected as spam and with a valid receiver.
Some mail servers accept all mail but quietly drop e-mails with no valid
receiver. This is too prevent spammers from guessing valid accounts by brute
force methods (semi random generated account names).

So what you effectively can check is if an e-mail address will not be
bounced. Or you can put it this way: If you will be able to deliver an
e-mail without but not if it also will reach a receiving account.

Further, some mail servers use gray listing which means that an unknown
sender will be asked to try again because the server claims to be busy. It
will continue to reply this way for an hour or so. Thus, a custom validating
function of yours will have to take this into account

Dear List:
 
Is there a way to validate an email address without actually sending an
email and waiting for the bounce?  Something akin to pinging an IP address?
 
TIA
