Because the reply information never changes.  i.e. a reply to a 
message doesn't change the reply text when resuming a draft.
Then those clients are broken IMHO.  What happens if you switch 
identities in those clients after resuming a message?  Do you get 2+ 
signatures?

Signatures are necessarily added at send time, as opposed to 
reply/forward information which is added at the initial compose time.   
A user should feel free to change their identity at any point prior to 
sending.

OK but just so you know :-

1. that when saving a draft through MIMP, it populates that with the 
REPLY information, so why not the signature.

2. that saving a draft from any other mail client will save the 
signature into the draft also.

3. drafts tend not to stay around for too long, so having signature in 
the right place is preferable really, as it is not as though the 
signature will change that often.

No this doesn't because it saves signature information in draft 
messages.  Which is not what we want.

Re-looking at this, I am going to revert the previous fix.  Mobile 
view is special since we don't put the reply text in the body either.   
This is getting overly complicated for a fix, especially since 
'sig_first' has already disappeared from the code.  So I am reverting 
to the previous behavior of adding the signature to the bottom, since 
that is never incorrect behavior.  (We have other prefs that aren't 
honored in the various views - this will be one of them).

I believe this resolves it...

see attached

With a reply and sig_first=1, it puts the signature at the top of the 
message before my actual typed reply... eg displaying.

1. Signature
2. Typed composition
3. Reply history



With a reply and sig_first=1, it should be...

1. Typed composition
2. Signature
3. Reply history

Fixed in IMP 5.0.x.  ('sig_first' has been removed in 5.1+).

MIMP signature position is always at the bottom of the message, as it 
is not respecting the preference to have the signature between the 
"new message" and the "previous replies".
