Zimbra is absolutely wonderful and I look forward to some much needed enhancements but until then I thought I would share some of my simple/hacky yet effective steps I have taken to accomplish specific tasks.
fyi: I'm running open source edition on Ubuntu 6.10 LTS, 40 Users (EDIT: 6.06 rather)
"Archive All" Email Account
always_bcc to an internal address email@example.com in main.cf
http://www.postfix.org/postconf.5.html (search for always_bcc)
As a financial firm we need to have a method of flagging certain terms appearing in the body of e-mail for review. Using filters in my firstname.lastname@example.org account I can create folders and tag items containing keywords in the body of the message
Filters can be very powerful. My only wish would be to be able to setup procedural "groups" of filters so that I could use more powerful logical conditions.
While the solutions I have seen for this involve a little too much customization for my taste (I hate it when upgrades break or remove functionality I added through hacking), I have a "good for the time being" solution for our interns here.
ALL interns email address' maintain the same email naming convention as everyone else plus a ".intern" appended to the name (e.g. "John Doe" email@example.com)
They are instructed to not send email to external accounts. firstname.lastname@example.org has a filter that says the following
if all of the following conditions are met, flag it
From contains ".email@example.com"
To does not contain "@mydomain.com"
I have to run now and get back to work but I thought I would share and hopefully get a thread going of similar tips / improvements to my own to help out fellow administrators.
