Way to go around an administrators account to send external email

I am using PHP mailer to send emails from a web application and have realized that only when an administrators account is used can the application send emails 开发者_如何转开发to external emails.

I am using SMTP. In order to send an email to an external email, the SMTP account needs to be an administrators account.

Is there a way around this?
