.Sh NAME
|
||||
.Nm smtpd-tables
|
||||
.Nd table API for the smtpd daemon
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Xr smtpd 8
|
||||
daemon provides a Simple Mail Transfer Protocol (SMTPD) implementation,
|
||||
which allows ordinary machines to become Mail eXchangers (MX).
|
||||
Some features that are commonly used by MX,
|
||||
such as querying databases for user credentials,
|
||||
are outside of the scope of SMTP and too complex to fit in
|
||||
.Xr smtpd 8 .
|
||||
.Pp
|
||||
Because an MX may need to provide these features,
|
||||
.Xr smtpd 8
|
||||
provides an API to implement
|
||||
.Xr table 5
|
||||
backends with a simple text-based protocol.
|
||||
.Sh DESIGN
|
||||
.Nm
|
||||
are programs that run as unique standalone processes,
|
||||
they do not share
|
||||
.Xr smtpd 8
|
||||
address space.
|
||||
They are executed by
|
||||
.Xr smtpd 8
|
||||
at startup and expected to run in an infinite loop,
|
||||
reading events and queries from standard input and
|
||||
writing responses to standard output.
|
||||
They are not allowed to terminate.
|
||||
.Pp
|
||||
Because
|
||||
.Nm
|
||||
are standalone programs that communicate with
|
||||
.Xr smtpd 8 ,
|
||||
they may run as different users than
|
||||
.Xr smtpd 8
|
||||
and may be written in any language.
|
||||
.Nm
|
||||
must not use blocking I/O,
|
||||
they must support answering asynchronously to
|
||||
.Xr smtpd 8 .
|
||||
.Sh PROTOCOL
|
||||
The protocol consist of human-readable lines exchanged between
|
||||
.Nm
|
||||
and
|
||||
.Xr smtpd 8 .
|
||||
.Pp
|
||||
The protocol begins with a handshake.
|
||||
First,
|
||||
.Xr smtpd 8
|
||||
provides
|
||||
.Nm
|
||||
with general configuration information in the form of
|
||||
key-value lines, terminated by
|
||||
.Ql config|ready .
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
config|smtpd-version|7.5.0
|
||||
config|protocol|0.1
|
||||
config|tablename|devs
|
||||
config|ready
|
||||
.Ed
|
||||
.Pp
|
||||
Then,
|
||||
.Nm
|
||||
register the supported services, terminating with
|
||||
.Ql register|ready .
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
register|alias
|
||||
register|credentials
|
||||
register|ready
|
||||
.Ed
|
||||
.Pp
|
||||
Finally,
|
||||
.Xr smtpd 8
|
||||
can start querying the table.
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
table|0.1|1713795082.354255|devs|lookup|alias|b72508d|op
|
||||
.Ed
|
||||
.Pp
|
||||
The
|
||||
.Dq |
|
||||
character is used to separate the fields and may only appear
|
||||
verbatim in the last field of the payload, in which case it
|
||||
should be considered a regular character and not a separator.
|
||||
No other field may contain a
|
||||
.Dq | .
|
||||
.Pp
|
||||
Each request has a common set of fields, followed by some
|
||||
other fields that are operation-specific.
|
||||
The common format consists of a protocol prefix
|
||||
.Sq table ,
|
||||
the protocol version, the timestamp and the table name.
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
table|0.1|1713795091.202157|devs
|
||||
.Ed
|
||||
.Pp
|
||||
The protocol is inherently asynchronous, so multiple request
|
||||
may be sent without waiting for the table to reply.
|
||||
All the replies have a common prefix, followed by the
|
||||
operation-specific response.
|
||||
The common format consist of a prefix with the operation name
|
||||
in followed by
|
||||
.Sq -result ,
|
||||
and the unique ID of the request.
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
lookup-result|b72508d
|
||||
.Ed
|
||||
.Pp
|
||||
The list of operations, operation-specific parameters and
|
||||
responses are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Cm update Ar id
|
||||
Ask the table to reload its configuration.
|
||||
The result is either
|
||||
.Sq ok
|
||||
on success or
|
||||
.Sq error
|
||||
upon a failure to do so.
|
||||
.It Cm check Ar service id query
|
||||
Check whether
|
||||
.Ar query
|
||||
is present in the table.
|
||||
The result is
|
||||
.Sq found
|
||||
if found,
|
||||
.Sq not-found
|
||||
if not, or
|
||||
.Sq error
|
||||
upon an error.
|
||||
.It Cm lookup Ar service id query
|
||||
Look up a value in the table for given the
|
||||
.Ar query .
|
||||
The result is
|
||||
.Sq found
|
||||
and the value if found,
|
||||
.Sq not-found
|
||||
if not found, or
|
||||
.Sq error
|
||||
upon an error.
|
||||
.It Cm fetch Ar service id
|
||||
Fetch the next item from the table.
|
||||
It is only supported for the
|
||||
.Ic source
|
||||
and
|
||||
.Ic relayhost
|
||||
services.
|
||||
The result is
|
||||
.Sq found
|
||||
and the value if found,
|
||||
.Sq not-found
|
||||
if not found, or
|
||||
.Sq error
|
||||
upon an error.
|
||||
.El
|
||||
.Pp
|
||||
Each service has a specific format for the result.
|
||||
The exact syntax for the values and eventually the keys are
|
||||
described in
|
||||
.Xr table 5 .
|
||||
The services and their result format are as follows:
|
||||
.Pp
|
||||
.Bl -tag -width mailaddrmap -compact
|
||||
.It Ic alias
|
||||
One or more aliases separated by a comma.

|
||||

||||

|
||||

|
||||
IPv4 and IPv6 address or netmask.
|
||||
.It Ic userinfo
