The PHP IMAP extension is NOT necessary at all (but won't harm)!
Below is a list of optional PHP extensions:
- --with-ldap Required for LDAP addressbooks
- --with-mhash Will improve charset decoding if present
- --with-mysql For MySQL storage of preferences or addressbooks
- --with-openssl When you want to use encrypted IMAP connections (TLS)
-
- If you're going to use LDAP in the addressbook, you must compile PHP
- with the LDAP extension. Include the MHASH extension to improve
- performance in character set decoding.
