There are hidden recipients, yes. That might explain the issue… 

Sorry for being so slow to answer - and thank you for persisting!

A possibility to improve this might be to first try the key for the email
address with which I received the email.

I cannot currently test this with a kmail based on kde5, because akonadi
currently does not work at all for me (fails to start and the error logs says
that all old accounts are missing).

This bug has only been reported for versions before 4.14, which have been
unsupported for at least two years now. Can anyone tell if this bug still
present?

If noone confirms this bug for a Framework-based version of kmail2 (version 5.0
or later, as part of KDE Applications 15.12 or later), it gets closed in about
three months.

 When I now click on one of my sent mails (or receive one of the mails - I
 always BCC myself) I have to enter multiple passwords: at least one for each
 key.

Are that more than two keys and are you sure that you are asked the passphrase
for different keys (check the pinentry message!)?

Are you sure this is different from the bug you reported two weeks earlier?

 at least one for each key.

Once for each of your keys or once for every target key?

 If you don't see your keyid at the output, gpg has to test all keys.

That doesn't make sense if his description is precise: If he hides the IDs of n
recipient keys and at least two of them are his own (which are probably the
last in the list) then he should have to try n-1 keys only because every key of
his own could decrypt the message.

Perhaps it helps to save the mail to a file, attach strace -p $PID -f -e
trace=execve to the kmail/kontact process (in order to see the gpg calls) and
then open the file.

Perhaps it makes sense to add some gpg debugging capability to KMail. If it is
activated all gpg calls and a copy of all used data are written to a directory.

Yes, I checked that multiple times.

There are two issues: Being asked for different keys and being ask twice for
the same. I am not 100% sure that I did not miss a different key ID in the
earlier bug, though I think it was the same (I cannot test right now: I'll only
be able to access my KDE machine again in a few days).

Best wishes,
Arne

Asking for all passwords sounds like you get mails, that hides the recipients.
Please test a mail with [1] to make sure you see your keyid at the output. If
you don't see your keyid at the output, gpg has to test all keys.

 (it took me quite some time to track down why I have to enter my password 
 twice, but I *think* that this is the reason) 
This other issue is unrelated, 'cause I use gpg without entering all
passphrases everytime.

Please discribe your crypto system a bit:
* gpg-agent/ gpg-agent.conf
* prinentry
* What kind of crypto do you use S-MIME/GPG Mime/Inline
