NAME
bugfiler - file bug reports in folders automatically SYNOPSIS
bugfiler [ mail directory ] DESCRIPTION
Bugfiler is a program to automatically intercept bug reports, summarize them and store them in the appropriate sub directories of the mail directory specified on the command line or the (system dependent) default. It is designed to be compatible with the Rand MH mail system. Bugfiler is normally invoked by the mail delivery program through aliases(5) with a line such as the following in /etc/aliases. bugs:"|bugfiler /usr/bugs/mail" It reads the message from the standard input or the named file, checks the format and returns mail acknowledging receipt or a message indi- cating the proper format. Valid reports are then summarized and filed in the appropriate folder; improperly formatted messages are filed in a folder named ``errors.'' Program maintainers can then log onto the system and check the summary file for bugs that pertain to them. Bug reports should be submitted in RFC822 format and aremust contain the following header lines to be properly indexed: Date: <date the report is received> From: <valid return address> Subject: <short summary of the problem> Index: <source directory>/<source file> <version> [Fix] In addition, the body of the message must contain a line which begins with ``Description:'' followed by zero or more lines describing the problem in detail and a line beginning with ``Repeat-By:'' followed by zero or more lines describing how to repeat the problem. If the keyword `Fix' is specified in the `Index' line, then there must also be a line beginning with ``Fix:'' followed by a diff of the old and new source files or a description of what was done to fix the problem. The `Index' line is the key to the filing mechanism. The source directory name must match one of the folder names in the mail directory. The message is then filed in this folder and a line appended to the summary file in the following format: <folder name>/<message number> <Index info> <Subject info> The bug report may also be redistributed according to the index. If the file maildir/.redist exists, it is examined for a line beginning with the index name followed with a tab. The remainder of this line contains a comma-separated list of mail addresses which should receive copies of bugs with this index. The list may be continued onto multiple lines by ending each but the last with a backslash (`'). FILES

Since mail can be forwarded in a number of different ways, bugfiler does not recognize forwarded mail and will reply/complain to the for- warder instead of the original sender unless there is a `Reply-To' field in the header. Duplicate messages should be discarded or recognized and put somewhere else. 4.2 Berkeley Distribution October 23, 1996 BUGFILER(8)

NAME
mailexec - run program on messages in mbox file or maildir SYNOPSIS
mailexec [-nvFR] mailbox program [arg ...] DESCRIPTION
mailexec runs a program over every message in mailbox, which must be an mbox-format mail file or maildir directory. For each message encountered, mailexec executes program with the specified arguments, supplying the message as standard input. mailexec synthesizes a "From " line and a "Return-Path:" header field for each message if the message does not already contain one. (This behavior can be modified by the -F and -R flags, described below.) When parsing mbox format files, mailexec unescapes "From " lines. If a line begins with one or more ">" characters followed by "From ", mailexec deletes one of the ">" characters. If you do not want this unescaping behavior, see the formail(1) utility, which has a -s flag that performs a similar function to mailexec. OPTIONS -n When processing a maildir, causes mailexec to look exclusively at "new" messages that have not yet been moved to the cur directory. -v Turns on verbose mode. If mailbox is a maildir, mailexec prints out the name of each file it processes inside the maildir. If mailbox is an mbox format file, mailexec prints the message-id of each message it processes (as long as messages have a message-id header). -F Suppresses printing of the initial "From " line at the beginning of each message. -R Suppresses printing of initial "Return-Path:" lines. EXAMPLES
To get the same behavior as the Unix from(1) command on a mail directory dir, you can run either of the following two commands: mailexec -n dir head -1 mailexec -n dir sed -ne 1p To convert an mbox-format file mbox into a maildir directory dir, you can run: mailexec mbox deliver dir/ Conversely, to convert maildir dir into an mbox-format file mbox, run: mailexec dir deliver mbox To train the spamassassin filter on a mail folder called spam containing unwanted messages, run: mailexec spam sa-learn --spam Note that this works whether spam is an mbox format file or a maildir directory. If you have an old mbox file or maildir directory box and wish to "import" the old mail into your web mail account, say example@gmail.com, you can run: mailexec -F box sendmail example@gmail.com Note again that this works whether box is an mbox format file or a maildir directory.

When reading from a maildir and synthesizing a "From " line, mailexec guesses the delivery date of the message based on the name of the file, which works in practice but could be considered dangerous since file names in maildirs are supposed to be opaque. Thus, while generally mailexec places sensible dates in "From " lines and processes maildir messages in order of delivery, it might be unwise to rely on this behavior. mailexec generates the time for the "From " line in the local time zone, as is customary on Unix. This could lead to loss of information when transferring mailboxes across time zones or combining mailboxes created in different timezones. Moreover, this practice is incompatible with qmail, which uses GMT in the "From " line. mailexec expects that if there is a "Return-Path:" header field, it will be the first header field in the message (possibly after the initial "From " line, which is not itself a header field). There are many different variants of the mbox message format. mailexec expects the "mboxrd" variant, in which each message is delimited by a "From " line at the beginning and a blank line at the end, and every line beginning with either "From " or one or more ">" characters followed by "From " is escaped by adding another ">" character. In particular, this means mailexec will incorrectly parse System V "mboxcl2" files, which use "Content-Length:" header fields to determine message boundaries rather than "From " lines. mailexec attempts to lock mbox format files, but will execute anyway even if it cannot obtain the lock. This allows it to work on read- only files, but if you are highly unlucky could result in the last message being truncated. There is no locking for maildir files. If a maildir is modified while mailexec is running over it, mailexec could miss messages. If you are concurrently manipulating the maildir with a mail reader, maildir could even miss old messages that just happen to have been moved from the new to the cur directory. mailexec will issue a warning if it fails to open a file that it had previously seen when scanning the directory.
