Bug 370385

Do you have the problem for other emails ?

could you give me an example as email which doesn't work ?
Thanks

I know this is an old bug, but I have this problem as well on kmail 19.04.0
kmail seems unable to correlate an email address to a saved kaddressbook contact when the part before the @ contains an underscore. example_email@example.com
On top of kmail not allowing the edit contact context menu for said address, all other options for the contact linked to that email are not recognized, such as avatar, preferred GnuPG key, and sign/encrypt preferences.

I can confirm this. It is an issue of the indexer in akonadi-search. I already created a unit test for it:

I still experience this bug with kmail Version 5.17.3 (21.04.3)

The bug is fixed, but the fix do no trigger a reindex of the contact. So you need to open the editpage of  the contact and press OK, than the contact is reindex and the emailadress with underscore is found afterwards.
