Hello Roudcube community

I have an exchange, which mainly handles the mail-flow.
I set it up to relay messages, where the mailbox is not on the exchange, to a Linux machine with roundcube (plesk).
This works without a problem except for the return way.
When I send a mail from roundcube to the exchange, it's searching for the mailbox on roundcube, and cannot find it.
Is there a way to configure roundcube like the exchange?
Like: "If mailbox not here, send it to exchange"

Thank you very much

Using PHP Version 7.1.25 on Windows 2008 Server SP2, connecting to SQL Server 2014 via loaded extension "php_sqlsrv_7_nts.dll" .

Before I wasn't able to connect to the database...now I get the login screen, however, whenever I try to login, I get the error "Your session is invalid or expired."

This is running Roundcube Version 0.8.4.

I have checked and I am correctly setting the timezone in php.ini (date.timezone= "America/New_York")

In the PHP logs I see this:
[20-Mar-2019 00:21:44 America/New_York] PHP Warning:  session_start(): Failed to read session data: user (path: C:\Windows\temp) in D:\websites\XXXXXXXXXXXXXX\program\include\rcmail.php on line 786

I have checked and the IUSR account has read/write permissions on the Temp folder (c:\Windows\Temp).

Any suggestions? I could obviously update roundcube since I am behind in versions, but I would prefer figuring out why it can't login now...

Thank you!

log directory have 755 permission 

we dont have anything recorded in the roundcube error log

Hi ,

We have a iredmail server with 2 domain names , mail.theracanncorp.com and mail.theracann.solutions.
With the roundcube client of the mail server we are able to login with both domain names.

When we try to configure roundcube client on a seperate server , with mail.theracanncorp.com we are able to login and see the inbox but with mail.theracann.solutions we are able to login but getting blank page , we are not able to load the mailbox.

Roudcube version : 1.3.6

Any help is much appreciated!
