Hi, thank you, your tip was partially successful. I did try an max php 
memory limit change up to 20mb, and my attachments limit got over my 
previous 400kb limit, but failed to send 2mb with same error.

Then I try again with 30mb memory limit, now Imp works ok beyond 5mb net 
attachments (~7mb after mime encoding). So you were on the right way!

Hope this helps to anybody else with same problem
