Latest roundcubemail package on Ubuntu 18.04 is 1.5.4.7-1~kolab1_all.deb, which as far as I can see has Net_SMTP in version 1.10.1 built-in. So, all should be ok, but I don't have Ubuntu system to verify on.

Anything different with Cyrus IMAP v3?

@mollekopf, imap.user_mailbox_create() returns False on error.

I think it is better to pass the invitation to Inbox for manual processing.

Sharing is not possible with the database driver. The label has been fixed in git.

Sounds to me like a client issue. We would need more info, including debug logs from syncroton.

This specific issue may be fixed with:

It looks to me it's rather CentOS7 issue. And it's old.

This is old.

Patch merged.

This can be found in preinst and postinst scripts and should be copied to prerm script.

reload_apache()

    if apache2ctl configtest 2>/dev/null; then
        invoke-rc.d apache2 $1 || true
    else
        echo "Your apache2 configuration is broken, so we're not restarting it for you."
    fi
}

@conathan I hesitate to merge this patch. Without it it works for me with Cyrus v3 DAV service as well as with standard Kolab DAV service (e.g. at kolabnow.com).

The sound is played if the event has an alarm of type "AUDIO" set. So, you can disable this per event, but I suppose a global option might make sense.

I recompiled and installed libkolabxml1v5 1.2.1-0~kolab3 but apache crashes now :

@nagifep aye, I did that to our own local servers (at the time I opened the ticket), working fine so far with the change. Apologies for not providing a update earlier.

The sending error might be related to T7133

Debian OS version doesn't matter.

I did apply the workaround patch and it did resolve the problem for my test case,
but i have not tested any other 8BITMIME Mails with non-UTF-8 charsets e.g. "ISO-8859-15" or "UTF-16"

Thanks for the patch @rledisez !

The referenced ticket T7247 discusses a Kolab installation on Debian 11 (and the various issues that arise).

You should only install the roundcubemail >= 1.5 package, which includes the contents of the roundcubemail-plugins-kolab package, so this is expected. I suppose something in the debian upgrade path doesn't quite work as expected.
