.SH SYNOPSIS
|
|

|
|
.nf
|
|
\fBpostmap /etc/postfix/access\fR
|
|
.SH DESCRIPTION
|
|
.ad
|
|
.fi
|
|
The optional \fBaccess\fR table directs the Postfix SMTP server
|
|
to selectively reject or accept mail from or to specific hosts,
|
|
domains, networks, host addresses or mail addresses.
|
|
|
|
The table serves as input to the \fBpostmap\fR(1) command. The
|
|
result, an indexed file in \fBdbm\fR or \fBdb\fR format,
|
|
is used for fast searching by the mail system. After an update
|
|
it may take a minute or so before the change becomes visible.
|
|
Issue a \fBpostfix reload\fR command to eliminate the delay.
|
|
|
|
The format of the access table is as follows:
|
|
.IP "blanks and comments"
|
|
Blank lines are ignored, as are lines beginning with `#'.
|
|
.IP "\fIpattern action\fR"
|
|
When \fIpattern\fR matches a mail address, domain or host address,
|
|
perform the corresponding \fIaction\fR.
|
|
