[pevik]

Here are 3 examples of different senders which are under cel--- via ltp user:

Some of them have somehow wrongly set git send-email, because the have in ML ... via ltp <ltp@lists.linux.it> (any hint, what is wrongly set?), but at least j.nixdorf@avm.de <j.nixdorf@avm.de> should have correct setup.

Also, it'd be great if patchwork could recognise different name in ... via ltp <ltp@lists.linux.it>.
