E-Mail-Adresse überprüfen

[Cheatah]

Hi,

wie kann man eine E-Mail-Adresse auf Existenz überprüfen?

es ist zwar die Perl-Doku, aber das macht keinen Unterschied:

perldoc perlfaq9
"""
How do I check a valid mail address?

You can't, at least, not in real time. Bummer, eh?

Without sending mail to the address and seeing whether there's a human on the other hand to answer you, you cannot determine whether a mail address is valid. Even if you apply the mail header standard, you can have problems, because there are deliverable addresses that aren't RFC-822 (the mail header standard) compliant, and addresses that aren't deliverable which are compliant.
