Ah, you don't store the mail locally but forward the mail to an external system outside of your control. Then, of course, you are between a rock and a hard place. But as the others said, a callout to an external system to verify a complete mail address is dangerous and will land you on multiple automatated blacklists. Verifing the existance of a domain via a DNS lookup is fine of course, but checking the localpart is bad. Please don't do this. Grüße, Sven. -- Sigmentation fault.
