[toaster] Emails stuck in local queue

[Dennis Erickson]

My users send emails with attachments that are usually around 10 to 12 
mb per file to each other.  The problem I am running into is that these 
emails are taking in upwards of an hour or more to be delivered to each 
other.  These are strictly local emails. 

I've googled a few different ideas on this one and keep running into a 
brick wall...  Any help or pointers in the right direction would be 
greatly appreciated.

Dennis.
