First of all, forgive me, I am not a programmer or even in the IT field. I am trying to fix an issue that affects my team as best I can with my limited knowledge and resources.

We have clients that have the ability to send us 'alerts' from their individual PCs via a mailsend.exe which routes to roundcube mail through a cPanel server. Roundcube then forwards our agents an email as an alert to our company Outlook mail so that they can remote into the client PC and resolve their technical support issue.

We get the email alerts just fine but overnight from 2/1/24 to 2/2/24 the email alerts became jumbled and no longer display properly. The alert inline attaches a facility.txt file which appears as the body text and is supposed to attach a .jpg file that is a screenstream image to give our agents a quick overview of the clients desktop so they have an idea of what the issue is before connecting.

Here is what the email looked like in roundcube on Feb 1st, client info has been redacted:
This is attachment 2.1.24 alert


And here is what it looked like after on Feb 2nd:
This is attachment 2.2.24 alert 1


I know it shows Feb 1st in the screenshot, the email was sent form a different timezone but arrived Feb 2nd EST.


Here is how the emails appeared in Outlook prior to Feb 2nd with the .jpg file at the top then the facility.txt file embeds inline in the body neatly:
This is attachment Outlook Before


And here is how it appears now, after Feb 2nd:
This is attachment Outlook After 1

If the client does not have a screenstream .jpg then the facility.txt attaches as normal and is embedded inline the email body just fine, but if a .jpg file is available then it sends the jumbled coded email. I'll put in the mailsend code in for what we have on each PC, the code itself has not been changed on the PCs but I'll blank where I have to conceal our information.



IF EXIST "C:\Windows\system\web\screenstream*.jpg" (GOTO EMLP) ELSE (GOTO EML)

:EMLP
ren c:\windows\system\web\screenstream*.jpg screenstream.jpg
mailsend -name "M2 ALERT" -f ins********.com -smtp mail.*******.com -port 465 -sub "INSTANT ******** ALARM" -attach "c:\windows\system\facility.txt,text/plain,i" -attach "C:\Windows\system\web\screenstream.jpg,img/jpg" -t p*******@m*****.com -cc p******@m*****.com +bc e*********@m******.com  -ssl  -auth -user ins**********@m******.com -pass 2********
exit
:EML
mailsend -name "M2 ALERT" -f ins********.com -smtp mail.******.com -port 465 -sub "INSTANT ******* ALARM" < c:\windows\system\facility.txt -t p*******@m******.com -cc p*****@m****.com +bc e*********@m*****.com -ssl  -auth -user ins*******@m******.com -pass 2*******
exit


I'm wondering if there is something that could have changed either with cPanel or roundcube mail that I can change back since this seems to have happened over night and is happening with each and every client when they send an 'alert' to us. I have also routed the mailsend on a demo PC to different emails in gmail and icloud to see if it was a platform issue and it persist on all mail platforms. I think the source of the issue lies either in roundcube or cPanel but after poking around I can't find any settings that seem to have caused this. HTML is set to display in display message and composed messages for both roundcube and Outlook.

If there is any insight to this, I'd be really appreciative. Again, I have no IT background, so I am very out of my depth here. I have almost no knowledge of roundcube and very little on cPanel as this set up was established quite a while ago long before I was part of my current team. All I know is the roundcube only seems to be a sort of springboard to forward the emails to our team on Outlook after the 'alert' button is pressed on a client pc and the mailsend.exe sends the information from the client PC to the cPanel server/roundcube mail which then forwards to the teams Outlook mail.

If more information is needed I can try to provide it as best I can.

HI,

I would like to install with Nextcloud, and the documentation seems somewhat limited. I did find this post here, https://github.com/rotdrop/nextcloud-roundcube?tab=readme-ov-file#installation and it said  the following:
"Due to the technology used -- Roundcube just runs in an iframe -- there are some restrictions caused by the same origin policy which at least nowadays is widely in use.

In principle this boils down to the point that the Nextcloud server installation and the Roundcube installation must be served in the same DNS domain.
NC Domain equals RC Domain
In this case nothing special has to be done. The administrator can simply enter the location of the Roundcube installation in the adminstrator settings of the app."

I am a somewhat limited admin, and not 100% clear about this, as to install the roundcube server on the vm as the nextcloud. Or install it separately but use the same dns, i guess...but i am not sure then how it would be the same...for example i could use domain.cloud for nextcloud and mail.domain.cloud....

Hi,

Thanks very much and please let us know, when the patch is available!

Thanks,
Marcus.

Hello Roundcube community,

We're integrating Roundcube as a webmail solution alongside our existing email platform. While email syncing via IMAP/SMTP works fine, we're struggling to sync contacts and calendars. Our platform supports CardDAV and CalDAV, and we're looking for guidance to implement this in Roundcube.

Could anyone share insights or point us towards resources on:

- Confirming Roundcube's compatibility with CardDAV/CalDAV for contact and calendar syncing.
- Steps or plugins required for this setup.
- Any potential challenges and how to overcome them.

Appreciate any help or suggestions you can offer!
