如何向 PHP 指定应该使用外部邮件服务器发送 mail()?
我的电子邮件托管在 Rackspace Email 上，并希望将其用作我网站上联系表单的邮件服务器.
I have my email hosted at Rackspace Email and would like to use that as my mail server for the contact form on my website.
查看 php.ini 文件，我只能指定 UNIX 系统上的 sendmail_path，我从中读取了指向实际在服务器上发送邮件的程序的点.
Looking at the php.ini file, I'm only able to specify the sendmail_path on UNIX systems, from which I've read points to the program that actually sends mail on the server.
我不想从我的 Ubuntu 服务器发送邮件，因为我没有足够的经验来为电子邮件进行安全设置...我想将所有内容转发到 Rackspace 的 mail.emailsrvr.com.
I do not want to send mail from my Ubuntu server since I'm not experienced enough to make a secure setup for email... I would like to relay everything to Rackspace's mail.emailsrvr.com.
我的问题是，如何向我的服务器上的 PHP 设置指定 mail() 函数应该使用外部邮件服务器?
My question is, how do I specify to the PHP setup on my server that the mail() function should be using an external mail server?
推荐答案
mail() 旨在移交给本地 SMTP 服务器，但做得很差.要获得适当的邮件支持，请使用 Swiftmailer 或 PHPMailer，两者都完全支持外部 SMTP 服务器并且更容易使用(另外还可以让您执行混合文本/html 邮件、附件等操作...)
mail() is intended to hand off to a local SMTP server, and does a poor job of it. For proper mail support, use Swiftmailer or PHPMailer, both of which fully support external SMTP servers and are far easier to use (plus letting you do things like mixed text/html mails, attachments, etc...)
