Nice addon but there should be regex pattern to show only addresses

Questa recensione riguarda una versione precedente (0.2.3) del componente aggiuntivo. 

The thing about this add-on is that there are no hardcoded patterns. You can use any regexp you need.

If you need only IP address you can use a regexp like this:
"^from .+?\[(.+?)\]\)(?: \(using .+ requested\))? by mx\.example\.com "

If you just want to hide TLS info:
"^from (.+?)(?: \(using .+ requested\))? by mx\.example\.com "

IF you are using multiple accounts you can specify several servers:
"^from (.+?)(?: \(using .+ requested\))? by (?:mx\.example\.com|mx\.example\.org|mxfront\d{1,2}[a-z].mail.yandex.net \(nwsmtp/Yandex\)) "
