Faster catch-all validations for HotMail (MSN and Live included) and GMail email addresses

Published on Thursday, May 12, 2011
We are pleased to announce, today, the release of EmailVerify.NET v4.2.18.1039!

This revision includes a new caching mechanism that makes validating HotMail and GMail email addresses faster than in any previous version of the component. The new features is enabled by default during the catch-all validation level (the one that proves a particular mail exchanger would reject fake email addresses, making you even more confident about a successful validation result) for @hotmail.com and @gmail.com email addresses and for every other known official domain name, including @hotmail.fr, @hotmail.es, @hotmail.de, @hotmail.jp, @hotmail.it, @hotmail.com.br, ..., as well as @live.be, @live.at, @live.no, @live.se and so on.

As usual, if you are an existing EmailVerify.NET v4 customer you have the right to download this new release for free, directly from your customer dashboard.

Cheers!
