[PHP-INSTALL] imap_open fail to work

Hello,

I'm compiling php 5.5.24 from source on my CentOS 6.6 Linux server and all
work except the imap module. Here the output I get when trying to test it
with my script:
array(1) {
  [0]=>
  string(52) "Connection failed to x.x.x.x,143: Invalid argument"
}

php is compiled with:
        --with-imap=shared
        --with-imap-ssl

libc-client version is:
libc-client-devel-2007e-11.el6.x86_64
libc-client-2007e-11.el6.x86_64

Testing with the same script on CentOS 6.6 with original php 5.3.3 work!

Gerhard,
