„The MAILMODE file
=================

The MAILMODE file is used to control the operation of the BATCHMAI
program, see batchmai(1). It is a common text file consisting of 
lines in one of two formats:

	smtpcsite S 16 64
	smtpsite S
	smtpfsite S F 64
	smtpgsite S G 64
	
	rmailsite R
	
(indentation only for clarity).

The first line says that the remote site smtpcsite gets mail batched
to 64KB and compressed with 16 bits for the r-command "rcsmtp". If
the compression bit number is 0, no compression takes place and the
r-command is "rsmtp". If the batch size is 0, then every mail "batch"
will contain exactly one mail. Both number fields are optional and
will be treated as 0 if missing, as shown in the second line: smtpsite
will get mail "batches" of one mail message each, uncompressed and 
addressed to the r-command "rsmtp".

The third line is similar to the first, but smtpfsite gets mail frozen
(with freeze(1)) instead of compressed. The r-command is "rfsmtp".

The forth line is similar to the first, but smtpgsite gets mail gzipped
(with gzip(1)) instead of compressed. The r-command is "rgsmtp".

The fourth line is really unnecessary because rmail mode is the default for
sites not mentioned in the MAILMODE file. Rmail mode is the run-of-the-mill
mode that should work with any UUCP system.

Empty lines and lines starting with a '#' character are ignored.
