how to set attachment size limit

[boxyball]

hello,

How do I set/change attachment size limit for all users?
And how would I make exceptions for certain users?

I currently DO NOT have sendmail limiting message size at all.
And I set php to 5mb as follows:
upload_max_filesize = 5M
Yet I still see a message that my limit is 2mb when I attempt to send a 3mb attachment in Roundcube.

Thanks in advance.

Make sure the limit is being applied to to Roundcube by checking the phpinfo() in the Roundcube directory. You may also need to change the post_max_size to support larger uploads.

that worked.  thanks.

Is it possible to make exceptions and have higher limits for certain users?  If so how?

You have to make a plugin that would set the php limits per-session.
