Unexpected token in IMAP response: '('

[jacargentina]

Doing this on a given folder with latest 1.0.13.0

var changes = folder.Search(MailKit.Search.SearchQuery.ChangedSince(this.HighestModSeq));

Logs this:

S: M00000006 OK Completed
C: M00000007 UID SEARCH RETURN () MODSEQ 46538
S: * SEARCH 56753 (MODSEQ 46539)
S: M00000007 OK Completed (1 msgs in 0.004 secs)

And i get an exception like this:

MailKit.Net.Imap.ImapProtocolException: Unexpected token in IMAP response: '('
en MailKit.Net.Imap.ImapFolder.SearchMatches(ImapEngine engine, ImapCommand ic, Int32 index)
en MailKit.Net.Imap.ImapEngine.ProcessUntaggedResponse(CancellationToken cancellationToken)
en MailKit.Net.Imap.ImapCommand.Step()
en MailKit.Net.Imap.ImapEngine.Iterate()
en MailKit.Net.Imap.ImapEngine.Wait(ImapCommand ic)
en MailKit.Net.Imap.ImapFolder.Search(SearchQuery query, CancellationToken cancellationToken)

I think the parser is not expecting the (MODSEQ 46539) part.

Using cyrus-imapd-2.4.17-8.fc21.x86_64

Maybe mailkit is not implementing the protocol as it should?

https://tools.ietf.org/html/rfc4551#section-3.5

If a client specifies a MODSEQ criterion in a SEARCH (or UID SEARCH)
command and the server returns a non-empty SEARCH result, the server
MUST also append (to the end of the untagged SEARCH response) the
highest mod-sequence for all messages being returned. See Section
3.4 for examples.

Thanks, I've just committed a fix for this.

@jacargentina would you be willing to get me the initial few lines of a log when connecting to Cyrus IMAP? I mostly care about the greeting, but if you could include the CAPABILITIES as well, that would be awesome. Thanks!
