Attempt to send a mail to group of contacts fails with error: 'Given email address is not valid, because it doesn't contain ".". You'll be unable to create valid mesages if you won't change your address.' Reproducible: Always Steps to Reproduce: 1. In address book create group of contacts. 2. Compose new mail and select new created group as recipient 3. try to send mail Actual Results: Error message shown, being unable to send a message. Expected Results: Mail send to all addresses from contact group It doesn't matter if group name was typed or selected from address book. This used to work with Kmail 4.12.4 and earlier.
Now in 4.13.2 contact group is indexed. I continue to look at it. so it will be better in 4.13.2
4.13.2 update fixed the issue. Thanks a lot.
