12MB mail stuck in Outlook



  • Hi,
    we are usign kopano 8.1 with univention/ucs4.1.3 -all patches applied.

    When trying to send 12MB Excel sheet via KOE 1.1.44 and z-push 2.3.4 I get following messages an mail is stuck in „Postausgang”.

    When using WebApp and DeskApp bigger attachements are send - What can I do?

    Hello @ThorstenS,

    there is actually also a memory limit set in the apache vhost of z-push:

        # Setting memory limit higher (larger attachments)
        php_value memory_limit 128M
    

    When you uncomment this and restart apache, the higher memory limit set in apache will be used and the mail will be sent.

    We recently stumbled upon this problem with lager attachments ourselves and memory consumption therefore has been improved with Z-Push 2.3.5 beta as well.

    PS: you should update KOE. There is now a 1.2.127.


  • Kopano

    Increasing the memory_limit is the easiest fix, but in some cases (e.g. when using send-as with KOE) the memory usage gets much higher. It could be that with 256 MB memory also gets exhausted.

    SendMail memory usage has been improved drastically in 2.3.5: https://forum.kopano.io/topic/61/z-push-2-3-5-beta1-released

    Final is scheduled for 01.03.2017, but feedback is of course very welcome before the final. ;)

    Cheers,
    Sebastian

    Thanks, I commented this line - tomorrow we will do our tests.

    Every version after KOE 1.1.44 crashed Outlook more worse and frequently, than 1.1.44 did. Today we installed 1.2.127 on some machine - looks much better. crossing fingers



  • @Sebastian
    As we are running univention corporate server, I prefer installing debs.
    Is there a repo for me? I will give it a try!


  • Kopano

    There is also a Univention repository for the betas.
    You can find all information here: https://wiki.z-hub.io/display/ZP/Installation

    Just use this repository (and proceed as described in the wiki): http://repo.z-hub.io/z-push:/pre-final/Univention_4.0/
