*exactly* that's it - many thanks!

%{login_status} -> ab[2].value = client->login_success ? "OK" : "Failed";
in case of deeper debugging one can always set "%$" temporary

when we can get rid of "TLSv1 with cipher" and only have the cipher the log would become
really tiny and easy to follow without too much linebreaking - not to forget the logsize
in case of a lot of POP3 users every few minutes
