+T-PROT -- TOFU protection
+=========================
1. What the hell is TOFU?
As the man page says:
text at the top; obviously they think that quoted text must not be
changed at all. This is quite annoying as it needlessly sends a lot of
data even when it is not required. Some editing of messages is desired.
- Please point these people to the page http://learn.to/edit_messages -
- thank you!

+ Thank you!
2. What does the script do?
- It detects, and when demanded hides annoying parts in rfc822 messages:
- TOFU, signatures (especially when they are too long), excessive
- punktuation, blocks of empty lines, trailing spaces and tabs.
- For use inside of MTAs or MDAs it may exit with appropriate libc exit
- codes, so annoying messages may be bounced easily.

3. For what can I use it?
There are several possibilities. One is to filter your email or news
- messages when displaying them in your MUA. Another is blocking annoying
- messages entirely from your system - using the script in some sendmail
- or procmail rule, or perhaps even inside innd.

4. Give me some example! What about an example configuration for the MUA
- mutt(1)?
+ mutt(1), or the NUA slrn(1)?
An example is included in the distribution. Please see the man page for
further details on the activated features.
-5. And what about other MUAs?
- I just use mutt, so I do not know how to filter messages in other MUAs.
- If you know how to incorporate t-prot e.g. in Gnus, please just drop me
- a note. ;)
+5. And what about other User Agents?
+ I just use mutt and slrn, but I will gladly accept configuration samples
+ for other user agents. There are already examples for mailcap(1) and the
+ Heirloom mailx (a.k.a. nail) in the contrib/ directory. The mutt example
+ works with mutt-kz as well.
-6. And what about an example for bouncing emails?
- Put a line like the following in your /etc/mail/aliases:
- ------SNIPP------
- notofu: |"/usr/local/bin/t-prot -cemtS -p=user@mydomain"
- ------SNIPP------
- (Do not forget to call `newaliases`.) Messages for notofu@mydomain will
- be scanned for TOFU. If t-prot found TOFU in a message, it will bounce,
- otherwise it will be forwarded to user@mydomain. This works great with
- sendmail, if you use another MTA you probably have to adapt it.

-7. Where did the idea come from?
- Many thanks to Gerhard H. Wrodnigg who uses a TOFU protection script
- in order to keep the responses to his cancel bot reasonably short. The

entire inspiration for this hack came from the "TOFU protection" line of
his script on many usenet postings.
