<b>NAME</b>
access - format of Postfix access table
<b>SYNOPSIS</b>
<b>postmap</b> <b>/etc/postfix/access</b>
<b>DESCRIPTION</b>
The optional <b>access</b> 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 <a href="postmap.1.html"><b>postmap</b>(1)</a> command. The
result, an indexed file in <b>dbm</b> or <b>db</b> 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 <b>postfix</b> <b>reload</b> command to eliminate the delay.
The format of the access table is as follows:
blanks and comments
Blank lines are ignored, as are lines beginning
with `#'.
<i>pattern</i> <i>action</i>
When <i>pattern</i> matches a mail address, domain or host
address, perform the corresponding <i>action</i>.
<b>PATTERNS</b>
Patterns are tried in the order as listed below:
<i>user</i>@<i>domain</i>
Matches the specified mail address.
<i>domain.name</i>
Matches the <i>domain.name</i> itself and any subdomain
thereof, either in hostnames or in mail addresses.
Top-level domains will never be matched.
<i>user</i>@ Matches all mail addresses with the specified user
part.
<i>net.work.addr.ess</i>
<i>net.work.addr</i>
<i>net.work</i>
<i>net</i> Matches any host address in the specified network.
A network address is a sequence of one or more
octets separated by ".".
<b>ACTIONS</b>
