[cobalt-users] raq4 - mime base64 problem with attachments

["Steve Bassi" <steve@xxxxxxxxx>]

I am using a php mime class to send an email with a jpeg and pdf attachment
from a webpage.

If I send a txt file there is no problem.

If I send a jpeg or pdf file , the file becomes corrupted and cant be
opened.

I have used the correct mime types application/pdf and images/jpeg and they
exist in /etc/httpd/conf/mime.types.

I have also checked the files on the webpage and they open fine.

(I have also tested pine and it sends attachments without problem.)

I have put the php class file below.

Any help or suggestions would be appreciated.
