[imp] Attachment size limit

[Josh Trutwin]

Hi,

Been having odd problems with attachments in Horde/Imp (2.2.6/3.2.6 with PhP 4.3.9/Apache 2.0.51/MySQL 4.0.21 on Linux 2.4.26).  It seems that large attachments sometimes do not get attached.  I figured this was a php memory/post/upload max setting, so I bumped up relevant php.ini settings to something absurd (see http://trutwins.homeip.net/phpinfo.php).  I thought it might be the output buffering setting which was set to 4096, but turning that off didn't change anything either.

My Horde/Imp installation is configured to use VFS stored in a MySQL database.  Oddly enough though when I send a message to myself with a small attachment that actually works, it doesn't appear as if VFS is even used (the horde_vfs table is empty).  After tooling around with the mysql query log I found out that attachments are actually being stored in mysql, but in the horde_sessionhandler table.  The session handler is indeed set to mysql.  

Will it cause problems if both session and vfs are set to use mysql and imp's compose['use_vfs'] is set to true in Imp's config?

Here is a message including headers for a failed attachment (Approx 4MB in size)

I have a feeling it's just something dumb, but I cannot be sure.

If there is any additional information I can provide let me know.

Thanks,
