Compatibility with RFC 2181

According to RFC2181, every DNS query needs to have a . at the end of
the name record you are requesting.

This will show that that name record is the root of the domain you are
asking
In some cases, when the . is missing, the hostname of the server the
code is running on will be appended to the name record when
checkdnsrr() is being executed and this will in turn return a false
positive when there is a wildcard DNS record for the root domain of the
hostname of the server.

A regression was introduced in 1.2.4 for long local parts.
Thanks to @craue

See #32
Error was caused by wrong negation and use of checkdnsr wasn't been taken into account when strict was set.
Now emails with warnings will fail when strict && DNS check or when strict with no DNS
Also, DNS check only raises warnings.

Valid Emails

• Improved detection of 4 valid email addresses

Invalid Emails

• Added 21 invalid emails in tests and added them to the validation, they are now detected as invalid.

Bug fixes reported by @brianfreytag on issue #19:

Invalid emails:

Valid emails:

• "brian,freytag"@gmail.com
• "brian freytag"@gmail.com

Are now detected as such.
