unable to parse:-

8.8.8.8 - [abc.def@example.com](mailto:abc.def@example.com) [28/Jan/2016:06:19:22 -0600] "PROPFIND /sssssss/ssssssss.php/ssssssss/ HTTP/1.1" 207 290 "-" "Mozilla/5.0 (Macintosh) mirall/1.8.1"

but if we remove @ from [abc.def@example.com](mailto:abc.def@example.com) it works.

This is addressed in [PR #106](https://github.com/logstash-plugins/logstash-patterns-core/pull/106) which is still open. With a sufficiently new logstash-patterns-core (2.0.0 or later) you can just copy the new definition of COMBINEDAPACHELOG into your grok filter (or put it in a separate patterns file under a new name).
