Tables that stores "Internet address" of SMTP node in SCOT

Hello All,

We store individual e-mail address in the "Address Type" space of SMTP node in SCOT transaction.

When we want to check if the internet address already exists or if we want to delete its very difficult to search.

I would like to know the table that stores the "Internet address" of SMTP node in SCOT.

I searched but not successful.

Thanks,

Subbu
