WOWorkersCount in sogo.conf is overwritten in the startup script with the setting of /etc/default/sogo option PREFORK.

And why did you install SOGo Version 2.2.10?

You should add the invers repos and get a recent 2.3.1

1. Thanks for the reply
2. I will try to use PREFORK instead. Will comment on results
3. SOGo 2.2.10 is in the standard repo of Ubuntu 15.04. So I presumed it would work.
4. Why is your repo not forwarded to Canonical? (From a conservative point of view, I am reluctant to add any external repos if not neccessary. I will try this as well though if recommended)

You can run 2.2.10, but not with the full functionality provided now.
My question wasn't meant as an offence and your reasoning is absolutely valid.
I didn't know Ubuntu 15.04 had this version "on board".

Every distribution decides on its own, when they freeze their packages. This is no decision Invers is responsible for or can influence a lot. Because of that Invers provides its own repositories.

2.2.10 is more than 9 months old now.
There where a lot of improvements and bugs fixed since then.
E.g. if you want to use ActiveSync, then you have no chance with that version, also MAPI support is ways better in the current version.

But don't get me wrong, it is up to you, which Version you run.

I wasn't offended (not likely to be anyway).

Installed Version 2.3.1 (@shiva.inverse 201507231602)
also installed sope4.9-gdl1-postgresql (as this is not automatically installed. There is a preference for postgres in the sogo.conf thus I was a little surprised)

deleted all postgresql tables and recreated sogo_view (as described in the manual)

Configured SOGo in such a way (adapted the provided config template):

In Firefox:

• The Send window is still blank
• the URL shown is: http://&lt;myserver>/SOGo/so/wolf/Mail/0/compose
• log entry: Aug 19 20:08:51 sogod [2616]: 62.40.177.65 "GET /SOGo/so/wolf/Mail/0/compose HTTP/1.1" 302 0/0 0.361 - - 0

In Chromium:

• The Send window appears
• the URL shown is: http://&lt;myserver>/SOGo/so/wolf/Mail/0/folderDrafts/newDraft1440007817-1/edit
• log entry: Aug 19 20:10:18 sogod [2618]: 62.40.177.65 "GET /SOGo/so/wolf/Mail/0/folderDrafts/newDraft1440007817-1/edit HTTP/1.1" 200 6320/0 0.299 22824 72% 0
• Now the mail gets sent :-)

Concluding:
It works generally but not in case of Firefox.

n.b.: The favicon is not honoured in this version.

Any ideas how I can get Firefox to work?

tried to enter the URL from Chromium into Firefox and sending succeeds (just the window does not close)

So I conclude, this is a redirection problem in FF (as 302 indicates).

Here is the configuration of the virtual host in Apache (2.4)

We use mod_rewrite to pass remote address to the SOGo proxy.

The remote address will appear in SOGo's log files and in the X-Forward

header of emails.

this virtualhost is only for carddav on Mac and not tested very well

I presume the Vhost on 8800 is not required at all
Other than that, I still could need a little help in adjusting this file.

I have a similar problem. If I have the Firefox plugin Ghostery enabled all popup window Sogo empty. It only helps the plugin to disable completely. Whitelist is not enough.

@inf: Thanks. This is not a SOGo issue.

Disabling Ghostery -> Send Window is displayed correctly (in fact any popup window that creates a new item, e.g. Calendar or Contact)

From my point of view: This issue can be closed and considered resolved.
