We resolved a couple of small bugs that existed in 9735, which was a critical update, and wanted to get those resolved this week along with a few smaller security items. We have another big release coming with some new features and functionality, but delayed the release to get 9735 out the door as soon as we could.

@Tim Uzzanti Is 9742 a critical update?

9742 is not the critical update. 9735 was the critical update, and 9742 fixes a couple of items in 9735 and also includes a few smaller security fixes which are not critical.

no issue here, 9742 works like a charm

Not sure if it's this version, a previous one or co-incidence, but users are saying their Outlooks are going out of sync. Their set up is an 'office' email address / mailbox that appears on several PC as well as their own personal one. Last week and today I have been contacted where the office emails are no longer in sync, eg, 48 missing / not synced last week, 60 this morning. These were two separate offices and two separate mailboxes

At the moment I rename the OST file and allow it to resync, and the missing emails then appear.

Putting it here as an observation

Only on the 9735 build. Now on 9742 it's solved!

Just had another user who is saying emails are going missing in Outlook sub folders. She is positive that she has not deleted them as they are not appearing in the deleted folder and when I impersonate her, I can see only the ones visible and nothing in deleted. I have managed to recover some / all from the message archive and also restoring yesterday backup to a different location for review / comparison

Terry,

There’s usually a valid reason why a message is no longer in a mailbox. It’s extremely rare for it to be a bug. Please reach out to support, and we’ll be happy to assist you in identifying the issue.

This seems a quite serious fix?
  • Security: Fixed a possible path traversal with user mailboxes.

All Good!

Updated cleanly (and quickly on my production Windows 2016 server).

Only issue I'm seeing is with Email Classification enabled it is NOT enforcing the 20,000 message limit per mailbox.  I have many clients that are over that... they too are in the Classificiation queue so it is taking a bit.

@Rod Strumbel This is the limit for messages in the inbox not the total size. Can you verify that their inbox folder is not over the limit. 

Kind Regards,

Yes, monitoring the processing queue... it clearly showed    8193/43234 (for example).
So it was processing Inboxes far bigger than 20,000 messages.
And yes, I double checked and my settings are still the 20,000 message default.

It has finished however and all is well from what I can tell.

Upgraded a Windows server to 9742 last week. So far no issues. Yesterday I upgraded two Unix test servers (Ubuntu) to 9742 and no issues. Tonight I'm upgrading a Unix (Ubuntu) production server. I will let you guys know how it goes, but I don't foresee any issues. The Unix upgrades are SO easy! I truly love Unix and SmarterMail!

Hi,

After the last update ST team wrote on release notes:
 
  • Security: Hardened legacy SOAP API calls for System Administrators.
  • Security: Hardened System Administrator token usage and permission access.
  • Security: Hardened user mailbox authentication caching
Now the Smarter Mail provider on Solid CP control panel cant add or update email accounts.

Server was unable to process request. ---> Could not create mailbox ---> The best overloaded method match for 'System.Exception.Exception(string)' has some invalid arguments
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
at SolidCP.EnterpriseServer.MailServerController.AddMailAccount(MailAccount item)

EDIT: We discover the problem, in solid cp the email policy should have complex password enable and should include, Uppercase letter, numbers and Non-alphanumeric symbols

Regards,

Upgraded another Unix server to 9742 tonight. This one is used as an incoming gateway only. No issues :)

Yes, we've updated a few servers. This build seems pretty solid.
