> Some time ago someone in #bro asked for matching mail addresses using the intel-framework. We realized, that the [seen-script|https://github.com/bro/bro/blob/master/scripts/policy/frameworks/intel/seen/smtp.bro] seems to contain a bug: Using {code}split_string_n(mail_address, /<.+>/, T, 1){code} to extract a mail address misses the last character and does not respect the possibility of multiple addresses.
> I will add a pcap later.
