    Default Upgrade or not when something is broken?

    Hi,

    I've increased RAM for my Zimbra installation from 4GB to 8GB and despite of all services are up'n'running, I experience some errors on WEBMAIL:
    - when login to Webmail randomly I get ERROR 500 Internal server error
    - when viewing ATTACHMENTS via webmail, if I click on attachment itself (PDF), I get ERROR 403 "must authenticate", but when I click on "Download" link, attachemnt gets downloaded and displayed in Adobe Reader without any problems

    My question:
    is it wise to UPGRADE 6.0.6 GA to 6.0.8 GA at this state? Or should I first solve problems and upgrade later?

    And subquestion:
    What could be broken by increasing virtual machine RAM? Must I run something on OS-level after I added some RAM?

    Hi,

    I would suggest you check the log files around the times of the random webmail errors.

    For the "must authenticate" message, I think it might be because you're using different URLs for the user session and the zimbra mailstore server. You may need to change the "public service host name" to fix this (have it point to the proxy server or normal user access URL).

    Upgrading from 6.0.6 to 6.0.8 will fix errors related to bugs in Zimbra (have a look at the release notes). But it looks like the problems you're having are related to your particular configuration.

    Hmmm...I've never know exactly what "Public service host name" stands for. Regarding to your post, more convenient name for this setting should be "Webmail service host name".

    So in my environment, where each domain uses the following:

    - important domains use mail antispam proxy, so they have setup in DNS:
    MX 10 antispam1.proxy.com
    MX 20 antispam2.proxy.com
    MX 30 antispam3.proxy.com
    This proxy then delivers mail to zimbra.mainserver.com:25
    I do not enter any of these proxies into Zimbra's config, since I do not know where they would fit.

    - other domains use
    MX 10 zimbra.mainserver.com
    This is what I enter for each domain as "Inbound SMTP host name"

    - each domain uses webmail and is configured in DNS
    A webmail.domain.com
    This is what should be entered in "Public service host name", right?

    Am I correct?
