It would be weird if this was related to the original message being sent 
with Outlook. Does the problem probably occur for certain recipients 
(who happen to be using Outlook)?

If you are using OpenPGP (or S/MIME) then KMail (resp. the cryptography 
backend) will check whether you have valid keys/certificates for the 
recipients. Checking the validity of keys/certificates can be 
expensive.

IIRC, Anne had similar problems which were related to her huge keyring.

I suggest checking this as follows:
- Make a backup of ~/.gnupg/pubring.gpg and ~/.gnupg/pubring.kbx.
- Delete ~/.gnupg/pubring.gpg and ~/.gnupg/pubring.kbx.
- Run 'gpg --list-keys'. gpg will create a new empty keyring.
- Run 'gpg --list-secret-keys --with-colon | grep ^sec | cut -d: -f5 | 
xargs gpg --recv-keys'. gpg will fetch the public keys corresponding to 
your secret keys from a keyserver.
- Now try whether the time it takes to send a message has improved.

Ingo
