Hi all,
i've got a strange behaviour with a BlackBerry Classic Phone (BBOS 10.3.2.2876) in combination with Dovecot 2.2.13 while trying to fetch mails.
Before burying myself into debugging sessions, i try to get an understanding if the following is a Client- or a Server-specific error in the behaviour:
CIGA8 UID FETCH 10009:10035 (UID FLAGS) (CHANGEDSINCE NOMODSEQ) CIGA8 BAD Error in IMAP command UID FETCH: Invalid CHANGEDSINCE modseq.
That's a broken client.
https://tools.ietf.org/html/rfc7162#section-3.1.4.1
"CHANGEDSINCE <mod-sequence>: The CHANGEDSINCE FETCH modifier allows the client to further subset the list of messages described by the sequence set. The information described by message data items is only returned for messages that have a mod-sequence bigger than <mod-sequence>."
