Hi,
I'm currently getting FPs from users sending themselves mail from personal
accounts with blank message bodies. Many times these messages are presumably
reminders, and as such have valid subject lines. Often these messages
contain attachments with the same filename as the subject, such as I believe
is sent by Windows 'Mail to Recipient' function. The problem is that these
messages seem to be triggering digest checks:
-0.0 SPF_PASS SPF: sender matches SPF recordcheck
I can only assume that digest checks are matching the hashes of other blank
messages, and that Razor et al ignore certain headers and mime types? Is
this behavior typical? I find it hard to believe I have screwed up my DCC,
Pyzor *and* Razor installations.
Can anyone think of any strategies for dealing with this? I've tried
educating my users, but it is like herding cats! :-(
1. Whitelist the senders in your digest software configs where applicable.
2. Whitelist the senders using whitelist_from_spf or whitelist_from_rcvd
if SPF records aren't present for the domain (you need a SPF_PASS hit,
and SA 3.1, for whitelist_from_spf to work... neutral won't do it).
