Thanks for informations Rik,
the email-validation would only be a "check". If it fails I may ask the user
to check again his email as the validation failed and then when he validate
again the address I save it. That's only for removing some mistyped emails
(even if I put 2 boxes and ask to write the email twice there is lot of
people typing email with errors).
I think I'll check the "undeliverable" email every month using only the
"undeliverable" emails.
Thank you again.
Bob
