Changing Email Attachment size limit

[grandpagenocide]

How would I change the size limit for email attachments? Im useing the perfect lamp set up for fedora core 6. I want to make an 8mb size limit on attachments. Where would I find the settings to change this?

There is no 8MB limit for attachemnets in ISPConfig. So either you have a limit on your postfix configuration (main.cf) or you use webmail and the 8 MB file exceeds the php upload limit.
