php - phpMailer Failing Authentication -

-

i've set automated email delivers message user.

nslookup

this nslookup details domain:

sballiance.co.uk name server ns2.mainnameserver.com. sballiance.co.uk mail handled 0 sballiance-co-uk.mail.protection.outlook.com. sballiance.co.uk descriptive text "v=spf1 include:spf.protection.outlook.com -all" sballiance.co.uk has address 176.32.230.12 sballiance.co.uk descriptive text "ms=ms71078976" sballiance.co.uk has soa record ns.mainnameserver.com. hostmaster.mainnameserver.com. 2014032747 86400 604800 2419200 10800 sballiance.co.uk name server ns.mainnameserver.com.

phpmailer setup

here important details phpmailer setup:

public $host          = 'sballiance-co-uk.mail.protection.outlook.com'; public $port          = 465; //i've kept default(?) public $smtpsecure    = ''; public $smtpauth      = true; //default false public $username      = 'no-reply@sballiance.co.uk'; public $password      = '%password%'; //this username/password combination has been set email address in cpanel equivalent (and works when checking webmail)

here actual function sending mail:

function sendmail($email,$username,$subject,$content){     include "mail/class.phpmailer.php";     include "mail/class.pop3.php";     include "mail/class.smtp.php";      $mail             = new phpmailer();     $body             = $content;      $mail->setfrom('no-reply@sballiance.co.uk', 'sb alliance');      $mail->addreplyto('no-reply@sballiance.co.uk', 'sb alliance');      $address = $email;     $mail->addaddress($address, $username);      $mail->subject    = $subject;      $mail->altbody    = 'this email requires compatible html email reader';      $mail->msghtml($body);      if(!$mail->send()) {         return "mailer error: " . $mail->errorinfo;     } else {         return "sent";     } }

i have tried changing $host others seem relevant, such mail.sballiance.co.uk (which webmail service) , outlook.office365.com no avail.

client-side reports

what can avoid emails failing authentication?

also, if other information required, let me know can more helpful in question.

you have spf record, server sending not listed in it, it's failing spf check:

spf=fail (sender ip 79.170.43.23)

you fix adding clause spf record:

ip4:79.170.43.23

or equivalent a clause.

your config wrong - in fact i'm surprised it's working @ as-is:

public $smtpsecure    = '';

it should be:

public $smtpsecure    = 'ssl';

on top of you've based code on old example, , you're including classes may not necessary. base code on up date example , latest phpmailer.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
