A while ago, I tried to investigate this in greater depth (I have a rather
old PowerMac with a 166MHz 604e, so it's a problem which really bites; even 
Nutscrape is much faster in en-/decoding than balsa!). It's not only that 
the libmutt routines are slow; for one message, the conversion is called 
multiple times. If I remember correctly, at least twice (for the message to 
be sent plus for the copy in the sentbox). If this is still ture, we could 
gain much more that a factor of two (maybe four?) if we introduce some kind 
of cache for converted attachments. I have no idea if this breaks MT at some 
point, but if it is not too difficult, it would be a great improvement.

Some MTA's have limits on the maximum size for mail reception, typically 
several MB's...
