Verification of the existence of an email account and reading it through a procedure?

Question

Good afternoon,
I wonder if there is any possibility of verifying the existence of an email account through a procedure?
And there is also the possibility to learn to read a particular email and store in a temporary table.
Thank you

That's not possible.
Many mail servers are configured not to send bounce messages if an invalid email address is specified.  If a mail server allows a bounce message, it becomes easy for spammers to compile a list of valid email addresses for the domain by trying various common combinations (i.e. [email protected], [email protected], etc.).  So you can't do it across every possible valid email address in the entire internet.
What is the actual problem you are trying to solve, though?  It seems highly unlikely that if you have email addresses that are part of an ERP that you really need to do this blindly.  What do you use the email addresses for?  Does the recipient have some reason to want to receive the emails that are sent to that address?  If so, it would generally make sense to let the recipient verify the address periodically.  On sign-up, assuming you are dealing with individuals outside of your company, you can send them a confirmation message that contains a link they need to click on to activate their account in order to verify that the email address they are providing is correct.
