Hello, I have a problem I can reproduce every time where at least one SEARCH command makes Courier-IMAP disconnect from the client with no warning. There is apparently nothing logged when this happens. The problem only occurs when there are messages with certain characters in the headers. I have observed it with apparent big5 encoding in the Subject: line, as well as messages with 8-bit characters (i.e. characters > 127) in the From: or To: lines.
The host system is Linux, running Courier-IMAP 1.4.4. This problem existed in my previous Courier version, too, something from last fall. To test, I took a problem message and put it in a mailbox called Bogus. This is the only message in the mailbox. Then, I manually executed the following sequence: root@imap:~# telnet localhost imap2 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Courier-IMAP ready.

The problem message had the subject line: Subject: =?big5?B?q0ggrUMgPyChQCC7WCCsQCCxzw==?= When I changed this to Subject: nothing the problem went away. Sam, can you give me any help on this? One of the clients my users use does a UID SEARCH as part of changing to a new folder. This results in these folders being inaccessible if there's any message in there with illegal characters. I agree that the characters shouldn't be there, but once they're there I can't let them make my users' email inaccessible. Thanks very much, Jeff -- Jeff Tucker Williams Consulting, Inc.
