Remove header Content-transfer-encoding: 8bit using PHPMailer

Is it possible to remove 开发者_JAVA技巧Content-transfer-encoding: 8bit from the email headers using PHPMailer?

Its been a while since I used this, but can you just search the source for where that encoding is set ... its probably either hard coded or in a property, that you'll possibly be able to set.

If not, you can extend that class and override the method(s) you need to. Sorry, I don't have an exact answer.
