Hi,

I'm using your library to check a lots of e-mail addresses from a database. I have IP addresses on my server and I bind those addresses to check e-mails. But ipv4 are rare those days and those IPs are now blacklisted by Microsoft servers.

Do you know if there is a way to use IPV6 only with your lib?

I am interested in the same thing, however not sure how many email services that support IPv6.

Off topic, did you find a way to process thousands of emails quickly? It seems to be going very slow as 1 thread.
