I recently tried setting up filters in Pine 4.33. I use the Courier IMAP
Every time I open my INBOX, or receive new messages, I get an error
message. The relevent section from Pine's logs is:
00000005 SEARCH ALL 1:36 UNDELETED SUBJECT [SRM98]
00000005 NO Error in IMAP command received by server.
The IMAP command sent by Pine seems reasonable to me. Is this a Courier
issue, or am I missing something?
