The IMAP server replied to the 'FETCH' command with a 'BAD' response: Error in IMAP command FETCH: Invalid messageset (0.000 + 0.041 + 0.040 secs).

To help me debug your issue, please explain:

• What were you trying to do?
• What happened?
• What did you expect to happen?
• Step-by-step reproduction instructions and/or a simple test case.

If you got an exception, please include the exception Message and StackTrace.

Please also INCLUDE A PROTOCOL LOG (scrubbed of any authentication data), especially
if you got an exception such as Syntax error in XYZ. Unexpected token: ....
If you do not include the protocol log, you will make me VERY UNHAPPY.

Without a protocol log, I CANNOT fix the issue. I will simply close the bug report.

To get a protocol log, follow one of the following code snippets:

// log to a file called 'imap.log'
var client = new ImapClient (new ProtocolLogger ("imap.log"));

// log to a file called 'pop3.log'
var client = new Pop3Client (new ProtocolLogger ("pop3.log"));

// log to a file called 'smtp.log'
var client = new SmtpClient (new ProtocolLogger ("smtp.log"));

Note: if the protocol log contains sensitive information, feel free to email it to me at
jestedfa@microsoft.com instead of including it in the GitHub issue.

Hello
First of all congratulations, good bookshop.
I'm using mimekit for the first time to develop an IMAP client and I'm having trouble with this call
infoMessage = cltIMAP.Inbox.Fetch ({iUId}, MessageSummaryItems.All)
I always get the error in the subject

Below is the log I have cleared the mail data as it is that of a customer

What could be the problem?
Thank you

[jstedfast]

That command should have worked, but your IMAP server seems finicky. It might not like a single message UID in the FETCH request.

I've just committed a fix to make it encode as 78270:78270 so that it's a set.

[jstedfast]

FWIW, normally you don't Fetch() for a single message, you normally do it for a batch of messages to be more efficient.

I probably won't get a chance to make a new nuget release for a week or so, so this fix won't show up for a little while yet.

[jstedfast]

I had to revert my fix for this due to the fact that it breaks expected behavior.

Syntax as defined by rfc3501:

fetch           = "FETCH" SP sequence-set SP ("ALL" / "FULL" / "FAST" /
                  fetch-att / "(" fetch-att *(SP fetch-att) ")")

sequence-set    = (seq-number / seq-range) *("," sequence-set)

So the fact that MailKit is encoding the FETCH command as:

A00000009 FETCH 78270 ALL

is perfectly valid syntax that your IMAP server is not properly handling.

[jstedfast]

That said, this will work for you in the next release:

var uid = new UniqueId (78270);
var uids = new UniqueIdRange (uid, uid);
var str = uids.ToString ();  // this will now be "78270:78270"

Thanks Jeffrey I do all the tests and update you on the results... Bye Il giorno sab 28 ott 2017 alle 19:30 Jeffrey Stedfast < notifications@github.com> ha scritto:
