Connected to mx.domain.com. Escape character is '^]'. 220 bosimpinc12 bizsmtp ESMTP server ready ``` ``` helo mydomain.com 250 bosimpinc12 hello [95.128.x.x], pleased to meet you ``` ``` MAIL FROM: 250 sender ok ``` ``` RCPT TO: 250 recipient ok ``` ``` quit 221 bosimpinc12 bizsmtp closing connection ``` Example ------- [](#example) ### Basic Usage [](#basic-usage) ``` require("vendor/autoload.php"); use peoplefone\mailValidatorMXServer; $class = new mailValidatorMXServer("mydomain.com", "me@mydomain.com"); $class->setContact("noreply@hotmail.com"); $class->setContact("noreply@gmail.com"); $class->setContact("noreply@yahoo.com"); $result = $class->validate(); print_r($result); ``` ### Result [](#result) The returned codes correspond to the RFC5321. For ordinary use, it can be assumed that the e-mail address is valid when code 250 is returned. ``` Array ( [0] => stdClass Object ( [mail] => noreply@gmail.com [host] => Array ( [0] => gmail-smtp-in.l.google.com [1] => alt1.gmail-smtp-in.l.google.com [2] => alt2.gmail-smtp-in.l.google.com [3] => alt3.gmail-smtp-in.l.google.com [4] => alt4.gmail-smtp-in.l.google.com ) [code] => 550 [text] => Requested action not taken: mailbox unavailable (e.g., mailbox not found, no access, or command rejected for policy reasons) ) [1] => stdClass Object ( [mail] => noreply@hotmail.com [host] => Array ( [0] => hotmail-com.olc.protection.outlook.com ) [code] => 250 [text] => Requested mail action okay, completed ) [2] => stdClass Object ( [mail] => noreply@yahoo.com [host] => Array ( [0] => mta7.am0.yahoodns.net [1] => mta6.am0.yahoodns.net [2] => mta5.am0.yahoodns.net ) [code] => 250 [text] => Requested mail action okay, completed ) ) ``` ### Settings Functions [](#settings-functions) ``` /** * Port of the remove MX Server. */ $class->setConnectionPort("25"); /** * Timeout of each connection. */ $class->setConnectionTimeOut("30"); /** * Timeout of each communication. * Note that some MX servers are configured to wait before responding or respond with multiple lines. * Perhaps you need to increase the stream timeout to get successful validation. */ $class->setStreamTimeOut("15"); /** * Pass the Boolean value TRUE to print the debug log. */ $class->validate(true); ``` ### Contact Functions [](#contact-functions) ``` $class->setContact("noreply@gmail.com"); $class->unsetContact("noreply@gmail.com"); $class->getContacts() ``` ### Health Score 25 — LowBetter than 37% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity8 Limited adoption so far Community4 Small or concentrated contributor base Maturity57 Maturing project, gaining track record How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
