After downloading 2.5-1..and do some testing..this is what i get:

I sent a 839kb pic and i get:

- These recipients of your message have been processed by the mail server:
(my##)/TYPE=PLMN@tmomail.net; Failed; 5.3.4 (message too big for system)

Remote MTA 10.184.33.185: network error


- SMTP protocol diagnostic: 552 MAIL FROM:<myname@comcast.net> max message size exceeded

So apparently any file greater than a certain size can not be accepted...but this is just 839kb? It's not that big. I sent one with 126kb and it did receive but the picture is STILL small like thumbnail size.
