Upon further investigation, it seems that if neither -P nor -a are
specified, the default account selected is the first one in the config
file. This got me suspicious, so I started reading the manual page
more closely and found the following snippets:
--read-envelope-from
Read the envelope from address from the From header of the
mail.
[...]
-f, --from=address
Set the envelope-from address. It is only used when
auto_from is off.
If no account was chosen yet (with --account or --host),
this option will choose the first account that has the given
envelope-from address (set with the from command). If no
such account is found, "default" is used.
[...]
The user can choose which account to use in one of three ways:
[...]
--from=address or --read-envelope-from
Choose the first account from the system or user
configuration file that has a matching envelope-from address
as specified by a from command. This works only when neither
--account nor --host is used.
[...]
The envelope_from=yes option lets Mutt use the -f option of
msmtp. Therefore msmtp chooses the first account that matches the
from address you@....
So I'm guessing that msmtp extracted the address from the From:
header, and then looks for the first account which has a 'from' value
matching that address.
However, this does not explain why the behaviour is different in
pretend mode; I strongly suspect that's a bug.
Additionally, I would suggest that in debug mode, the output should be
altered to include an explanation of the account selection process.
Cheers,
Adam
