IMAP connection reject the password under Mac Mail

[anto_davidraj]

Hai,

We have one issue, around 20 users are connecting a single IMAP account using Mac Mail. Frequently (5-10 times per day) they received pop up window, to enter the password and it rejected (password is correct) and it may allow if they check after 5 to 10 minutes, and also some time it allow immediately.

Any idea.

Thanks

Antu

Same problem just started with Thunderbird on mac. Not to mention that when it is working, it's too slow to be usable.

[knobby]

Tried restarting Scalix because of other problems I'm working on and it would not stop after 10 minute wait. Rebooted the server and now I am no longer being prompted for imap password every time I try to connect.

Every time I am seeing this and have looked for the cause I had to notice that it was rather a network related issue than a problem with the server.

Please verify if you can see a response with "telnet yourserver imap" from Terminal.app if you see this again.

cheers,
Dirk

Hai

I changed the general.cfg

IMAP_CONNECTION_LIMIT=1000
IMAP_CONNRATE_LIMIT=20

Even after i change the configuration, i am receiving the error. I checked the connection, it is not more than 300.

I have tried adjusting the connection limits without success. Today I am not able to login to imap or swa at all. I am able to get some log output from imap:

I notice in sac that the Remote Client Interface service is not running and does not respond to a start request. Or at least its status icon is red, along with the Item Structure Server and Local Client Interface under Other Services. When I try to start them, I don't seem to get any output from onshowlog.

[knobby]

I must not have posted right earlier, I did check network connectivity each time this problem has occurred. It has always appeared to be working properly.

[knobby]

I have just tried a /etc/init.d/scalix restart and got this output:

Stopping Scalix services (j9mail): omoff : [OM 4838] Cannot shut down subsystem Local Client Interface,
there is already a shut down in progress.
omoff : [OM 4838] Cannot shut down subsystem Remote Client Interface,
there is already a shut down in progress.

Obviously related to the services I mentioned above. This is happening to any imap client. If I telnet to imap it does this:
Escape character is '^]'.
* OK Scalix IMAP server 11.3.0.11339 ready on j9mail.j9tech.com

I found one post, it telling that

In general.cfg, set the parameter

MAX_SIGNON_PER_USER

But i didn't found any parameter like that, and also i didn't found anything about that in Scalix documentation.

Thanks

(Note: knobby, i think you are discussing about different issue than me)

I've been having the same problem lately, always with Mac users.

Users can login ok from SWA on the Mac, or Outlook/Thunderbird-IMAP from PCs,
But no on MAC Mail. This is what I get in the fatal log:

imapSatAuthenticate:Could not register with Session Monitor. usr_Signon() returned: SIGNON LIMIT REACHED, errno: Success

I'm using 11.4.1 server

Some suggestions to modify general.cfg from other posts don't apply to this version. in addition, I'm really far below the stated limits.

So, what is the problem?
What is the fix?

[schmoe90]

Well, the only thing we have to look at is SIGNON LIMIT REACHED - how many times is the user signed on (omstat -u pc)?

[jaime.pinto]

Not that many, only 8:
omstat -u pc | grep <User> | wc -l
8

So, we still don't know what the problem is, but the temporary fix was:
omtidyu -M -B -u "User"
rm -rf imap-cache/ 00000v8.ofs/
omscan -Avfx -U "User/mail2"

It was not necessary to restart the services.

In addition, SIGNON LIMIT REACHED does not exit in general.cfg for version 11.4.1

[jaime.pinto]

I continue to have strange issues with Mac Mail on a number of users:

1) Emails send out don't necessarily get filed into the "Sent" folder of Mac Mail

2) When they get sent, sometimes they show in the "Sent" folder of Mac Mail, but not in the equivalent folder as seen from SWA, i.e., "Sent Messages".

3) More often than I'd like to admit, the Mac Mail / scalix interaction seems to be adversely affecting the structure of the user mailstore, and not letting the user login due to "improper name/password" I have been forced to use .omscan and omtidyu on the mailstore of the user to recover from this situation, and sometimes even restart the all mail services with omshut and omrc (this affects everybody else).

Is anybody else noticing similar issues with v11.4.1 of the server?
Has this been acknowledged and possibly fixed for v11.4.3, which I hope will also fix the free/busy problems we've been having?

At this point I'm advising users not to rely on Mac Mail anymore.

I1) Emails send out don't necessarily get filed into the "Sent" folder of Mac Mail

2) When they get sent, sometimes they show in the "Sent" folder of Mac Mail, but not in the equivalent folder as seen from SWA, i.e., "Sent Messages".

The IMAP standard has no definition for the name of the Sent items folder and there is no way for an IMAP client to determine the proper folder from the server through discovery. Mail and Scalix IMAP have a different understanding about which is the right folder.

What you need to do after setting up Mail is to select the Sent Messages folder (by name, not the one Mail highlights as Special) in the Scalix Account's folder Tree, then go to Mailbox->UseThisMailboxFor->Sent and you will be all good. You should do the same thing for Deleted Items.

3) More often than I'd like to admit, the Mac Mail / scalix interaction seems to be adversely affecting the structure of the user mailstore, and not letting the user login due to "improper name/password" I have been forced to use .omscan and omtidyu on the mailstore of the user to recover from this situation, and sometimes even restart the all mail services with omshut and omrc (this affects everybody else).

I would suggest opening a support case for this as this must be something specific to you situation. I use Apple Mail about 23h/day (that's what people tell me from my responsiveness), have a 7 GB mailstore, completely offline-sync, and half a million messages in it, adding 200-300 every day and it works fine. After some month of use and several hard network interruptions I've seen Apple Mail's local cache go out of sync with Scalix and had to recreate it, however I've not and never seen any issue created by it on the server side. I almost forgot to mention that I have four Macs running it against my mailbox at various times, depending on where I am, and sometimes at least two of those in parallel.

I may want to add that I use Leopard, with all patches and updates installed. My mailbox is concurrently accessed by our internal ActiveSync server, sometimes other IMAP clients, CalDAV, SWA on a regular basis and even Outlook when I am at my desk, for testing purposes. So far, it's withstood all temptation to break badly. I like it. And it's pretty fast as well.

Is anybody else noticing similar issues with v11.4.1 of the server?
Has this been acknowledged and possibly fixed for v11.4.3, which I hope will also fix the free/busy problems we've been having?

Again, please either open a support case or be more specific with the issues or corruption you're seeing. Also, what FreeBusy problems are you seeing?

At this point I'm advising users not to rely on Mac Mail anymore.

Sorry to hear that,
Florian

In looking at this, there is a general.cfg tweak, MAX_SIGNON_PER_USER shown in the Admin Guide. But it's listed in the UAL section, so I don't know if it has any effect for IMAP or not, though my guess would be no. The Admin Guide also indicates that it has a default limit of 17.

Can Devel comment? I've been asked about this with a client too, although I'm not seeing it with any of our MACs.
