我正在使用PHPMailer并将其设置为SMTP用于发送电子邮件。问题是，它没有连接到 SMTP 服务器，而是尝试从托管服务器发送邮件。这是我创建的代码：
$mail = new PHPMailer ( true );
$mail->IsSMTP ();
$mail->Host = $res ['outgoingmailserverhost'];
if(in_array($res['outgoingmailserverencryptedconnectiontype'],array('ssl','tls'))){
$mail->SMTPSecure = $res ['outgoingmailserverencryptedconnectiontype'];
}
$mail->SMTPDebug = 2;
$mail->SMTPAuth = true;
$mail->Port = ( int ) $res ['outgoingmailserverport'];
$mail->Username = $imapUser;
$mail->Password = $imapPass;
$mail->SetFrom($fromaddress,$fromname);
$mail->AddReplyTo($fromaddress,$fromname);
foreach($allrecipients as $type=>$recip){
foreach($recip as $recs){
if($type==='cc'){
$mail->AddCC($recs);
} elseif($type==='bcc'){
$mail->AddBCC($recs);
} elseif($type==='to'){
$mail->AddAddress($recs);
}
}
}
$mail->Subject = $subject;
$mail->AltBody = $textbody;
$mail->MsgHTML($htmlbody);
if($attachment1!==null){
$attachment1= BASE_PATH . '/data/uploads/' . $attachment1;
$mail->AddAttachment($attachment1);
}
if($attachment2!==null){
$attachment2= BASE_PATH . '/data/uploads/' . $attachment2;
$mail->AddAttachment($attachment2);
}
if($attachment3!==null){
$attachment3= BASE_PATH . '/data/uploads/' . $attachment3;
$mail->AddAttachment($attachment3);
}
$mail->Send();
