How to increase SquirrelMail maximum attachment size from 2MB.
SquirrelMail is written in PHP, the max attachment size for webmail is inherited from the “upload_max_filesize” value set forth in php.ini
Here you go..
1, Locate your php.ini.
2, Open it in a text editor
3, Search for upload_max_filesize.
4, Change 2M to something else, for example 5M.
5, If the upload_max_filesize is larger than post_max_size, you must increase post_max_size so that it’s bigger than upload_max_size
6, If the value of post_max_size is larger than memory_limit, you must increase memory_limit so that it’s larger than post_max_size.
7, Save your changes to the file.
8, Restart your web server.
Note 1:
There’s no documented max upload size.
Note 2:
If uploading the file is slow, you may have to increase the max_execution_time so that the script does not terminate before the entire file is uploaded.
Thank you
