My institution uses Zimbra (7.1.4_GA_2555) to provide a webmail interface. One problem I have with this system is that it automatically closes (expires) the current session relatively frequently, and more importantly: It does that very often while I am writing a mail! I can then log back in, and find most of that email saved as a draft, but often the last sentence or so has been sent to tumbolia. This is extremely annoying.
– Is there anything I as a user can do to prevent this, some hidden preference (the overt ones don't help), or something I can configure in my browser (Chrome on Linux) to maybe automatically extend the session periodically?
– Is there a Zimbra server setting that I can ask my admin to adjust? I realize the correct procedure would be that I report the problem to him (which I did) and then he researches a solution – but he didn't, so I gather if I can provide the solution on a silver platter I have a better chance.
