- If anyone out there has a broken Rmail FCC file and is cursing me for
- posting a crappy "fix", please accept my humblest appologies. If it's
- any consolation, my FCC file got knackered too. This article describes
- the steps I took to fix it.
-
- If your file is still broken after you've tried this, mail me and I'll
- do my best to help sort it out.

-
- First, the history of the wretched thing so that we're both talking
- about the same thing:-
-
- 1) I noticed that FCC copies of messages sent using "sendmail" were
- getting lost if the FCC file was being visited in RMAIL mode (or any
- other mode for that matter).
-
- I traced the fault to `mail-do-fcc' in sendmail.el, which simply
- used `write-region' to append the message to the disk file
- regardless of whether it was being visited.
-
- I knew that GNUS didn't have the same problem so I checked how it
- did it. This led to the first "sendmail.el" change that I posted in
- gnu.emacs.sources and gnu.emacs.gnus - "Improved FCC handling for
- sendmail" - on August 21st.
-
- 2) As I started using sendmail FCCs more regularly, I noticed that
- there was nothing in the To/From field in the RMAIL-summary buffer
- and that the message header in the RMAIL buffer didn't have the
- "Date:" and "From:" fields that are present in normal mail.
-
- RMAIL-summary usually shows who a message is from, except that when
- it is from you, it shows who it is to. I assumed that the To/From
- field was left blank because RMAIL-summary couldn't find a "From:"
- line, so I came up with my ill-fated fix of changing "sendmail.el"
- to insert "Date: ...\nFrom: user". This was posted to gnu.emacs.bug
- - "sendmail.el - FCC output doesn't have "From:" header field" - on
- August 28th.
-
- It worked fine when I tested it. Unfortunately I didn't realise
- that I was always visiting the FCC file when I tested, so I didn't
- spot the "unvisited file" problem.
-
- 3) On September 2nd I realised that message FCCs weren't there when I
- read the FCC file using RMAIL. After a fair amount of digging
- around I realised that my "fix" was causing the problem because new
- messages weren't being appended to the FCC file in UNIX mail format.
- I fixed my FCC file (eventually) and corrected my fix so that it did
- The Right Thing when the file wasn't being visited or wasn't in
- RMAIL mode. I then started looking at my BABYL conversion routine,
- and realised that I could use RMAIL's own. While I was looking
- through this i realised that the thing that was messing up the
- header conversion was the format of the date in the "From" line.
-
- I posted the fixed fix to gnu.emacs.bug and gnu.emacs.sources -
- "BUG ALERT: sendmail.el - FCC output doesn't have "From: " header
- field" - on September 2nd.
-
-
- Strewth! That was a bit long! Anyway, I'm assuming you got screwed up
- after applying the patch mentioned in (2) above, so here's what you've
- got to do to recover your FCC file.
-
- 1) Run RMAIL on the file and do `h' to view the summary buffer. Note
- which message is the last one.
-
- 2) Switch to the RMAIL buffer and do
-
- C-x w (widen)
- M-x fundamental-mode RET
-
- to get you out of RMAIL mode so you can edit the raw file.
-
- 3) Find the last message, as noted in (1). Go to the end of the message
- and, on a line on its own, insert ^_ (a single character, control
- underscore) - you can do this by typing C-q C-_. Note that this
- character may already be there (Rmail puts one at the end of the
- file). If it is there, *don't* put another one in.
-
- 4) Move down the file looking for the start of each new message. They
- should begin something like:-
-
- Date: Thu Sep 3 17:47:05 1992
- From: me
-
- Change these 2 lines to be:-
-
- From me Thu Sep 3 17:47:05 BST 1992
-
- Remember to put the time zone in.
-
- 5) Check for control characters (eg ^_) at the *end* of the file.
- Delete them.
-
- 6) Save the file (C-x C-s) and kill the buffer (C-x k RET).
-
- 7) Cross your fingers :-) and run RMAIL on the file. It should convert
- all your missing messages into BABYL format and everything should be
- wonderful.
-
- 8) Apply the corrected patch to your sendmail.el.
