  seems i'm hitting a timeout of 15s - anyway to increase that ?

  btw. I can see if I retry the timeout gets increased - eventually hitting 60s but the attempt after that is just stuck. no timeout. and no new data.

  actually - after 120s - same problem.

  I think the issue is your are requesting "*" instead of i.e. "INBOX/*"

  I just confirmed that if I use imapfilter and list_all('INBOX/*') things works okey.

  Doing list_all('*') times out for me too.

  Anyway to limit this first query which is including alot of unrelevant folders?

  found Hidden preference so I could add:

  namespaceResponse = "((\"INBOX\" \"/\")) NIL NIL";

  and it seems things are better now.

  • State changed from “new” to “resolved”

  Sorry for the late reply on this one. I'm glad you found a solution yourself.

  Some servers use an INBOX prefix (or some other prefix) and some servers do not. The response from the server seems to indicate that it doesn't:

  S: * NAMESPACE (("" "/")) (("/home/" "/")) NIL
  

  But your experiments show that it probably does. I'm not sure how MailMate could reliably detect that automatically (I assume other email clients do work for you, but I don't know how).

  You could try connecting to the server using telnet/openssl to avoid the timeout. Just to see what is eventually returned by Zimbra for the LIST command and whether or not something is exposed via IMAP which you should consider a security risk. (Let me know if you would like instructions.)

  Give me the instructions for what you want and I can filter out the results for anything risky ;)

  Apparently I cannot connect to your server, but it's something like this:

  First connect:

  > openssl s_client -connect mail.corp.redhat.com:imaps
  

  (You might need to add -crlf as an argument.)

  Then login:

  0 LOGIN name password
  

  And then do the list:

  1 LIST "" "*"
  

  Wait to see if it ever returns a result.

  I did this and yes, it eventually returned a result.

  Somewhere between 5 and 10 minutes.

  I don't think other mail clients asks for the full list every time. I think they check if the folder list has changed in the background.

  Was the result the same as with the INBOX argument?

  Very few email clients would wait 5-10 minutes for a response. It is more likely that they somehow know they must use the INBOX prefix.

  benny - sorry for forgetting to answer this one.

  Just to state that when not using INBOX I get additional folders, including my very big archive which uses a folder per quarter.

  I believe having INBOX/* also prevents me from having mailmate detect my actual Archive folder which is outside the INBOX and in /Archive instead.

  benny January 20th, 2014 @ 12:09 PM

  I would think it would require tens of thousands of folders to make Zimbra hang for that long before replying…

  And yes, "INBOX" does prevent you from seeing anything outside that hierarchy. You might be able to do something like this though:

  namespaceResponse = "(("INBOX" "/") ("Archive/Whatever" "/")) NIL NIL";
  

  I haven't tested it though.
