note 119148 added to function.imap-search

imap_search function is not fully compatible with IMAP4. the c-client used as of now supports only IMAP2 and some search criterion will not be available for use such as "OR" So a php code similar to: $inbox = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'foo@example.com', 'pass123', OP_READONLY); $search_string = 'SUBJECT "FedEx" OR SUBJECT "USPS"'; $emails = imap_search($inbox, $search_string); will throw an error saying "Unknown search criterion" observations and reference: PHP source trace:(ref: https://github.com/php/php-src/blob/master/ext/imap/php_imap.c) /ext/imap/php_imap.c -> line no : 4126 imap_search => line no : 4148 c-client library source trace: src/c-client/mail.c -> line no : 3973 internal.txt -> line no : 1919 => mail_criteria() criteria IMAP2-format search criteria string WARNING: This function does not accept IMAP4 search criteria.
