OSTYPE

You MUST define an operating system environment, or the configuration file build will puke. There are several environments available; look at the "ostype" directory for the current list. This macro changes things like the location of the alias file and queue directory. Some of these files are identical to one another.

It is IMPERATIVE that the OSTYPE occur before any MAILER definitions. In general, the OSTYPE macro should go immediately after any version information, and MAILER definitions should always go last.

Operating system definitions are usually easy to write. They may define the following variables (everything defaults, so an ostype file may be empty). Unfortunately, the list of configuration-supported systems is not as broad as the list of source-supported systems, since many of the source contributors do not include corresponding ostype files.

ALIAS_FILE	[/etc/aliases] The location of the text version of the alias file(s). It can be a comma-separated list of names (but be sure you quote values with commas in them -- for example, use define(`ALIAS_FILE', `a,b') to get `"a"` and `"b"` both listed as alias files; otherwise the `define()` primitive only sees `"a"`).
HELP_FILE	[/usr/lib/sendmail.hf] The name of the file containing information printed in response to the SMTP `HELP` command.
QUEUE_DIR	[/var/spool/mqueue] The directory containing queue files.
STATUS_FILE	[/etc/sendmail.st] The file containing status information.
LOCAL_MAILER_PATH	[/bin/mail] The program used to deliver local mail.
LOCAL_MAILER_FLAGS	[rmn] The flags used by the `local` mailer. The flags `lsDFM` are always included.
LOCAL_MAILER_ARGS	[mail -d $u] The arguments passed to deliver local mail.
LOCAL_MAILER_MAX	[undefined] If defined, the maximum size of local mail that you are willing to accept.
LOCAL_MAILER_CHARSET	[undefined] If defined, messages containing 8-bit data that ARRIVE from an address that resolves to the `local` mailer and which are converted to MIME will be labeled with this character set.
LOCAL_SHELL_PATH	[/bin/sh] The shell used to deliver piped email.
LOCAL_SHELL_FLAGS	[eu] The flags used by the `prog` mailer. The flags `lsDFM` are always included.
LOCAL_SHELL_ARGS	[sh -c $u] The arguments passed to deliver `prog` mail.
LOCAL_SHELL_DIR	[$z:/] The directory search path in which the shell should run.
USENET_MAILER_PATH	[/usr/lib/news/inews] The name of the program used to submit news.
USENET_MAILER_FLAGS	[rlsDFMmn] The mailer flags for the `usenet` mailer.

USENET_MAILER_MAX	[100000] The maximum size of messages that will be accepted by the `usenet` mailer.
SMTP_MAILER_FLAGS	[undefined] Flags added to SMTP mailer. Default flags are `mDFMUX' for all SMTP-based mailers; the `"esmtp"` mailer adds `a' and `"smtp8"` adds `8'.
SMTP_MAILER_MAX	[undefined] The maximum size of messages that will be transported using the `smtp`, `smtp8`, or `esmtp` mailers.
SMTP_MAILER_ARGS	[IPC $h] The arguments passed to the `smtp` mailer. About the only reason you would want to change this would be to change the default port.
ESMTP_MAILER_ARGS	[IPC $h] The arguments passed to the `esmtp` mailer.
SMTP8_MAILER_ARGS	[IPC $h] The arguments passed to the `smtp8` mailer.
RELAY_MAILER_ARGS	[IPC $h] The arguments passed to the `relay` mailer.
SMTP_MAILER_CHARSET	[undefined] If defined, messages containing 8-bit data that ARRIVE from an address that resolves to one of the SMTP mailers and which are converted to MIME will be labeled with this character set.
UUCP_MAILER_PATH	[/usr/bin/uux] The program used to send UUCP mail.
UUCP_MAILER_FLAGS	[undefined] Flags added to UUCP mailer. Default flags are `DFMhuU' (and `m' for `uucp-new` mailer, minus `U' for `uucp-dom` mailer).
UUCP_MAILER_ARGS	[uux - -r -z -a$g -gC $h!rmail ($u)] The arguments passed to the UUCP mailer.
UUCP_MAILER_MAX	[100000] The maximum size message accepted for transmission by the UUCP mailers.
UUCP_MAILER_CHARSET	[undefined] If defined, messages containing 8-bit data that ARRIVE from an address that resolves to one of the UUCP mailers and which are converted to MIME will be labeled with this character set.

FAX_MAILER_ARGS	[mailfax $u $h $f] The arguments passed to the `FAX` mailer.
FAX_MAILER_MAX	[100000] The maximum size message accepted for transmission by FAX.
POP_MAILER_PATH	[/usr/lib/mh/spop] The pathname of the `POP` mailer.
POP_MAILER_FLAGS	[Penu] Flags added to `POP` mailer. Flags `"lsDFM"` are always added.
POP_MAILER_ARGS	[pop $u] The arguments passed to the `POP` mailer.
PROCMAIL_MAILER_PATH	[/usr/local/bin/procmail] The path to the `procmail` program. This is also used by `FEATURE(local_procmail)`.
PROCMAIL_MAILER_FLAGS	[SPhnu9] Flags added to `Procmail` mailer. Flags ``DFM'' are always set. This is NOT used by `FEATURE(local_procmail)`; tweak `LOCAL_MAILER_FLAGS` instead.
PROCMAIL_MAILER_ARGS	[procmail -Y -m $h $f $u] The arguments passed to the `Procmail` mailer. This is NOT used by `FEATURE(local_procmail)`; tweak `LOCAL_MAILER_ARGS` instead.
PROCMAIL_MAILER_MAX	[undefined] If set, the maximum size message that will be accepted by the `procmail` mailer.
MAIL11_MAILER_PATH	[/usr/etc/mail11] The path to the `mail11` mailer.
