Boost maximum email size

[lostonearth]

Hi,

I developed a php script which allows my website members to upload multiple photos and files by email. With a cronjob the emails are read and the individual file distributed to the members profile in the website.

The problem :
Emails with more then 15MB attached to them, are bounced and returned to sender.

I'm looking for a solution or advise on how to boost the maximum email size.

For example: send a email with 25MB of attached photos!

Here is what my users have to do:

You can edit the exim.conf file and increase the max size of emails.
The path to this file is usually /etc/exim.conf

Keep in mind that you do need root access to perform the operation.
