No, it's SIZE=. I did that since SIZE is not known if body gets converted "on
the fly". Currently it's pretty senseless since nothing gets converted at all.

I exchanged some mails with Phil and told him that I wrote this patch back in
2006 (4.62). After he asked me to provide it here I reworked it for 4.76 and
here it is;-)

At least this patch improves "allow_8bitmime" behavior since it relays the
BODY= information to MTAs announcing 8BITMIME.

Maybe we can use something like fallback host... 7bit_fallback_host? to relay
messages which need conversion to an extra host able to do this instead of

We use "allow_8bitmime" (without this patch) for years now and it breaks less
then without it. Even major MUAs like Thunderbird don't care about 8BITMIME and
send 8bit encoded without BODY= announcement anyway.
