Summary: Support Internet Message Format for SMTP
Project: Bro Issue Tracker
Issue Type: Improvement
Affects Versions: git/master
Reporter: Jan Grashoefer
Having a look at an
I noticed problem with SMTP: Bro assumes that e.g. the To-field contains a comma-separated
list of mail-addresses. According to [RFC
] there is also the possibility to
use groups (see below).
To: "Test Group":<firstname.lastname@example.org>,<email@example.com>;
Regarding groups I am not sure whether they can be nested. If I am not mistaken, the
] in the RFC would allow nested
groups. But in my understanding this is not desired for the Destination Address Fields:
the field name, which is either "To", "Cc", or "Bcc",
followed by a comma-separated list of one or more addresses (either mailbox or group
That leads to two questions:
# Would it be sufficient for Bro to log just the addresses (usually whats inside <
and >) without description (quoted with " )?
# Should Bro support nested group-syntax?
I think option 1 (just log the plain addresses) should be sufficient, because if someone
is interested in more details, one could have a look at the raw headers.
