XLIII. IMAP, POP3 and NNTP Functions

�vod

These functions are not limited to the IMAP protocol, despite their name. The underlying c-client library also supports NNTP, POP3 and local mailbox access methods.

Po�adavky

This extension requires the c-client library to be installed. Grab the latest version from and compile it.

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 libc-client.a.

Pozn�mka: To build the c-client library with SSL or/and Kerberos support read the docs supplied with the package.

Instalace

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 --with-imap=/usr/local/imap-2000b. 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

Pozn�mka: Depending how the c-client was configured, you might also need to add --with-imap-ssl=/path/to/openssl/ and/or --with-kerberos=/path/to/kerberos into the PHP configure line.

I have a pretty much stock set-up of SuSE 8.1 Personal (Apache, PHP et al built by me) and IMAP-2004 refused to build for me.



What I found was, using the make lsu (for SuSE) almost worked built I was getting odd build results, i.e. make failures.



The problem? GCC 3.2. If you don't have an older GCC available, please install one! I installed the gcc_old package from SuSE and built with the following command:



CC=gcc297 make lsu SSLTYPE=none



The result was a perfect build. So if you are getting errors, please try an earlier build of GCC.

For compiling this extension without compiling imap from sources I did (this was mandrake):



Install the following rpms:

imap

imap-devel

openssl

openssl-devel

krb5

krb5-devel

pam

pam-devel



Do the trick:

# mkdir /usr/include/imap/lib

# cp /usr/lib/libc-client-PHP4.a /usr/include/imap/lib/libc-client.a



And the configure line:

./configure <options> --with-imap=/usr/include/imap --with-imap-ssl



(don't forget --enable-pear ;)

The manual mentions:

"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 libc-client.a. 

"



A. Please do not copy rather make symbolic links like this:

ln -s c-client include

ln -s c-client lib



B. You do not need to copy c-client.a to libc-client.a.

The make command used to compile the imap-2002e source code creates the symbolic link from c-client.a to libc-client.a



The imap client version used for the above two points is:

1. imap-2002e



my 2 cents,

Additionally to Mauricio's procedure; You must check the Makefile to find the correct system type that you are compiling on. Mauricio's example assumes you are using Linux. -Check the README for imap-xxxx for further details.

Additionally to Mauricio's procedure, I had to make a symlink to the c-client library this way:



cd imap-xxxx/c-client

ln -s c-client.a libc-client.a



(Tested with imap-200e)

A tip for imap support installation:



With SSL support:

------------------

tar -zxf imap-xxxxx.tar.Z

cd imap-xxxxx

make slx

ln -sf c-client include

ln -sf c-client lib

cd ..

tar -jxf php-4.3.x.tar.bz2

cd php-4.3.x

./configure --with-imap=../imap-xxxxx --with-imap-ssl=/path-to-openssl



With out SSL support:

---------------------

tar -zxf imap-xxxxx.tar.Z

cd imap-xxxxx

make slx SSLTYPE=none

ln -sf c-client include

ln -sf c-client lib

cd ..

tar -jxf php-4.3.x.tar.bz2

cd php-4.3.x

./configure --with-imap=../imap-xxxxx



Good Luck

I experienced a problem when adding IMAP support into PHP.  The php configure script would die when trying to see if "IMAP Works..." and the config.log would complain about libc-client.a references.  

It was similar to the problem reported here: 

 



I resolved it by compiling IMAP like this (replace <ARCH> with the proper OS type for your system, get that from the top of the Makefile):



make <ARCH> SSLTYPE=none



That turned off the SSL support in the IMAP files and seemed to resolve my php compile problem.



BTW, I also followed the directions about making a new /usr/local/imap... directory that are mentioned at the top of the page.

After having numerous problems compiling PHP with IMAP support, both PHP problems and IMAP problems I found this simple solution to the problem, which I've tried with several versions of IMAP and all worked perfectly!



tar -zxf imap-xxxxx.tar.Z

cd imap-xxxxx

make slx

ln -sf c-client include

ln -sf c-client lib

cd ..

tar -jxf php-4.3.x.tar.bz2

cd php-4.3.x

./configure --with-imap=../imap-xxxxx



It worked everytime for me, hope it does for you!

Beware!

If you are trying to make a connection with POP3 mailbox,then some of IMAP functions will not work correctly as you might expecting .This is because the difference of workings in POP3 and IMAP protocols.

These functions work correctly for IMAP mailboxes but some of the fnctions will return nothing, when connected to a POP3 mailbox.(even no error message).

please don't copy the .h files in the system include directory! the unix.h file from the washington.edu c-client conflicts with another file called unix.h

make a dir called "imap" in either /usr/include or /usr/local/include or whatever you wish, copy the header files there and the .a file prefix'ish in /usr/lib or /usr/local/lib or whatever you used for the include files.

then tell configure with --with-imap=/usr the "prefix" of your installation. 

then works without problem ;)

I just found something a bit bizarre.  I was having problems with the pages taking too long to load (15-20sec) when they opened an imap connection.  I was pulling my hair out trying to figure out what was wrong.





Turns out it was quite simple.  I was letting it default to 143 for the port.  When i specified the port number (i.e. {localhost:143} rather than {localhost} )  It reduced page load time to a few seconds.

I have found the order in which you connect to you POP server with IMAP 2000 and your database with PostgreSQL 7.1.2 can cause problems.





Make sure that you connect first to your POP server then get your db connection. This will prevent you from getting an invalid stream from imap_open().
