Sending when `sign failed'

[henry atting]

I am confused of gnus' behaviour when pgp/mime signing failes.
Suppose I did fill in the wrong gpg password and then got the error
message 'sign failed', what will gnus do? Send it not signed or hold it
back until I enter the correct password?
As I (unfortunately to often) enter the wrong password some recipients
got mails twice, but I could not reproduce this behaviour (with myself as
recipient).
