Squirrel mail is one of the popular open source web mail client.
By default squirrel mail supports upto 2MB attachments.

To increase/decrease attachment size in squirrel mail you need to update it in php.ini as explained below:
- Open /etc/php.ini with any editor
- Search for upload_max_filesize in /etc/php.ini, by default it will be upload_max_filesize = 2M
- Just change the value of 2M (which 2MB) as you required (Example: upload_max_filesize = 5M).
- After updating in php.ini restart httpd service with service httpd restart
- Now just upload any any attchment and test.
