updated errors message if hostname response to A/AAAA records

[OlegPhenomenon]

What's the issue?

• The problem is an error message appearing during email validation, even though the validation result is positive. In other words, the email passes the validation and has an attribute success = true, but still, in the errors field, contains error information such as target host(s) not found.

Why does this error occur?

• The hostname of the email box is checked by the Truemail gem, and indeed, MX record-based email validation may yield an error. However, this does not mean the email is invalid. The email can also resolve to A/AAAA records, which allows the use of this mailbox. The problem is that Truemail logs error information, while additional validation based on A/AAAA records returns a positive result.

How did you solve it?

• If the A/AAAA validation result turned out to be positive, then I update the error information to the following text: target host(s) not found, but was able to find A/AAAA records for domain.

How to test?

• Appropriate emails must be available that do not pass MX validation but have A/AAAA records at the same time. Run the rake task bundle exec rake verify_email:check_all -- --check_level=mx --spam_protect=true, and make sure that the ValidationEvent entries associated with the contact have a success==true result, as well as the error record target host(s) not found, but was able to find A/AAAA records for domain
