所以我正在使用 mandrill 发送电子邮件，这在这里有效：
"html" : "Hi '.$fullName.', <br><br> Welcome to BlaBla ! We\'re glad to have you on board. <br><br> Please visit this link to confirm your email address:<br> http://www.BlaBla.com/verifyEmail.php?email='.$email.'&token='.$token.'<br><br> If you need any help, please do not hesitate to reply to this email and we will get in touch shortly. <br> <br> Thank you, <br> The BlaBla Crew",
但这无法发送电子邮件：
"html" : "Hi '.$fullName.', <br><br> Welcome to BlaBla ! We\'re glad to have you on board. <br><br> Please visit this link to confirm your email address:<br> <a href="blabla.com">http://www.BlaBla.com/verifyEmail.php?email='.$email.'&token='.$token.'</a><br><br> If you need any help, please do not hesitate to reply to this email and we will get in touch shortly. <br> <br> Thank you, <br> The BlaBla Crew",
困惑了一个小时。任何想法？
