It's important that you do not copy the IMAP source files directly into
the system include directory as there may be conflicts. Instead, create
a new directory inside the system include directory, such as
/usr/local/imap-2000b/ (location and name
depend on your setup and IMAP version), and inside this new
directory create additional directories named lib/
and include/. From the c-client
directory from your IMAP source tree, copy all the *.h
files into include/ and all the
*.c files into lib/.
Additionally when you compiled IMAP, a file named
c-client.a was created. Also put this in the
lib/ directory but rename it as
To build the c-client library with SSL or/and Kerberos support read
the docs supplied with the package.
In Mandrake Linux, the IMAP library (libc-client.a)
is compiled without Kerberos support. A separate version with SSL
(client-PHP4.a) is installed. The library must
be recompiled in order to add Kerberos support.
To get these functions to work, you have to compile PHP with
--with-imap[=DIR], where DIR is the
c-client install prefix. From our example above, you would use
This location depends on where you created this directory according to the
description above. Windows users may include the
php_imap.dll DLL in php.ini.
IMAP is not supported on systems earlier that Windows 2000. This is because it
uses encryption functions in order to enable SSL connections to the mail
Depending how the c-client was configured, you might also need to add
into the PHP configure line.
The IMAP, recode,
YAZ and Cyrus
extensions cannot be used in conjuction, because they
both share the same internal symbol.
This document can't go into detail on all the topics touched by
the provided functions. Further information is provided by the
documentation of the c-client library source
(docs/internal.txt). and the following RFC
