Description: Insert mails from inbox file(s) into a table.
This program can read group [mail_to_db] from the my.cnf
file. You may want to have db and table set there at least.
Usage: $progname [options] file1 [file2 file3 ...] [>& /path/to/log.txt]
or: $progname [options] --create [file1 file2...] [>& /path/to/log.txt]
Options:
--help Show this help and exit.
--version Show the version number and exit.
--debug Print some extra information during the run.
--host=... Hostname to be used. (Using: $opt_host)
--port=# TCP/IP port to be used with connection. (Using: $opt_port)
--socket=... MySQL UNIX socket to be used with connection.
(Using: $opt_socket)
--db=... Database to be used. (Using: $opt_db)
--table=... Table name for mails. (Using: $opt_table)
--user=... Username for connecting. (Using: $opt_user)
--password=... Password for the user.
--max_mail_size=# Maximum size of a mail.
Beware of the downside letting this variable be too big;
you may easily end up inserting a lot of attached
binary files (like MS Word documents etc), which take
space, make the database slower and are not really
searchable anyway. (Default: $opt_max_mail_size)
--create Create the mails table. This can be done with the first run.
--test Dry run. Print the queries and the result as it would be.
--no_path When inserting the file name, leave out any paths of
the name.
--stop_on_error Stop the run, if an unexpected, but not fatal error occurs
during the run. Without this option some fields may get
unwanted values. --debug will also report about these.
