main.validateEmails(0x28b2b1?)

Hello Team,

I'm a PHP Laravel developer with no prior experience in Go. I've installed Go version go1.21.6 on Linux/amd64. I am looking to validate emails with domain and MX records using Go.

I've attempted to run go build, go run ., and go run [specific files], but encountered various errors each time.

Could you please guide me through the necessary steps to run this validation process so that I can effectively validate emails?

Thank you.

[ISSUE] Typographical error on line 49 in domain_list_match.go file

Issue description

// Returns true if whitelist validation enebled, otherwise returns false
func (validation *validationDomainListMatch) isWhitelistValidation() bool {
validatorResult := validation.result
return validatorResult.Configuration.WhitelistValidation
}

As seen above, the comment reads Returns true if whitelist validation "enabled"
This is a typo, as the word should be "enabled"

Question

When using Truemail as my main engine for validating emails I found that every time I validate Yahoo emails the results are always valid/true. After I try to debug the problems, turn out that Yahoo accepts all email addresses in the RCPT TO section, so even if the email doesn't exist the return from the Yahoo MX server will always be OK (250). After I continued to the DATA section in the SMTP session the Yahoo MX server just returned the mailbox not exist message.

Here is the detail:

$ swaks -s mta5.am0.yahoodns.net:25 -f [email protected] -t [email protected]
=== Trying mta5.am0.yahoodns.net:25...
=== Connected to mta5.am0.yahoodns.net.

<** 552 1 Requested mail action aborted, mailbox not found

*** Remote host closed connection unexpectedly.

So is there any workaround for this problem? I tried various validators that are available online and the result is valid.

Is the only way is just to do/continue the SMTP session until the DATA section? If it is, doesn't it will send the message to the target email if the email is valid?

Question

It is not possible to easily access the content of truemail.validatorResult.SmtpDebug because the fields of smtpRequest are private. How to access easily to these fields ?

I would like to know why smtp check fail by look at SmtpDebug[i].response. Is that a choice to put those structs private ?

Thanks for your work

The bug is in the runSession function when creating smtp client we ignore the error, however calling either Send or Close in case there is an error causes panic
