that rejects destinations not in $relay_domains. By Lamont
Jones of Hewlett-Packard. File: smtpd/smtpd_check.c.
Robustness: postconf now validates the syntax of all main.cf
parameters.
Security: do not allow weird characters in the expansion

Documentation: added a sample postfix alias to the examples
in the INSTALL document and in the conf/aliases file.
Reminded by Simon J. Mudd @ alltrading.com.

* The VBUF buffer is defined by 1) its structure, by 2) the VBUF_GET() and
* 3) VBUF_PUT() operations that automatically handle buffer empty and
* buffer full conditions, and 4) by the VBUF_SPACE() operation that allows
* the user to reserve buffer space ahead of time, to allow for situations
* where calling VBUF_PUT() is not possible or desirable.
*
* The VBUF buffer does not specify primitives for memory allocation or
* deallocation. The purpose is to allow different applications to have
* different strategies: a memory-resident buffer; a memory-mapped file; or
* a stdio-like window to an open file. Each application provides its own
* get(), put() and space() methods that perform the necessary magic.
*
* This interface is pretty normal. With one exception: the number of bytes
* left to read is negated. This is done so that we can change direction
* between reading and writing on the fly.
