SYMPTOMS
The Internet Message Access Protocol (IMAP) allows a client to search for information contained in messages. The SEARCH command has the ability to search the Internet headers of a message. However, when it is searching for some header information, the IMAP server may fail to return the messages that contain the information. Here is a sample conversation to show the problem:

CLIENT: 0001 login USER1 USER1 RESPONSE: 0001 OK LOGIN completed

CLIENT: 0002 SELECT INBOX RESPONSE: S: * 2 EXISTS * 1 RECENT * FLAGS (\Seen \Answered \Flagged \Deleted \Draft) * OK [PERMANENTFLAGS (\Seen \Answered \Flagged \Deleted \Draft)] * OK [UIDVALIDITY 49] UIDVALIDITY value. 0002 OK [READ-WRITE] SELECT completed.

CLIENT: 0003 uid search header content-type text/html RESPONSE: * SEARCH 0003 OK SEARCH completed.

The last response is incorrect. The correct response looks like the following:

RESPONSE: * SEARCH 1 0003 OK SEARCH completed

To verify that the information exists in the message, you can use the FETCH command. The following is an example of the FETCH command that can show the data is in the message:

CLIENT: 0004 fetch 1 (body[header.fields (content-type)]) RESPONSE: Content-Type: text/html; charset=&quot;iso-8859-1&quot;
 * 1 FETCH (BODY[HEADER.FIELDS (content-type)] {51}

) 0004 OK FETCH completed.

Notice that the string &quot;text/html&quot; is in the header. The FETCH command correctly retrieves the data, but the SEARCH command does not.



CAUSE
When IMAP asks the Internet E-mail engine (IMAIL) for the data, an incorrect flag is passed, which causes the Internet headers to be suppressed. When the search is performed, no data matches, so no message set is returned to the SEARCH command.
