I've recently had some problems regarding upgrading Zimbra while also upgrading my OS at the same time. To be more specific: I wanted to upgrade Zimbra Open Source Edition from 8.0.5 to 8.6 and at the same time upgrade Ubuntu Server from 12.04 to 14.04. The problem I encountered was that I couldn't get it to work, Zimbra threw a lot of Perl-related exceptions and since the Zimbra forum isn't very communicative I had to reroll to my backup to be up and running after the weekend again. So what is the correct process?
I have a web server setup with postfix which is relaying email to a zimbra server. This working fine however I have attempted to send a few thousand emails and now the connection from postfix to zimbra is timing out. All of the emails have been deferred on the postfix queue.
If I try to send individual emails from postfix to zimbra it works fine. But if I try to flush the postfix queue all of the emails time out. In mail.log the emails look like this:
postfix/error[2494]: 32B0950C04: to=, relay=none, delay=19431, delays=19402/29/0/0.01, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to mail.server.com[123.45.678.91]:25: Connection timed out)
I have also noticed that in the above message it says "relay=none" for these emails that are failing. But the emails that do send say "relay=domainname.com".
How I can resolve this, by sending the emails in the queue and avoiding this from happening again?
I work at a university, where we have staff members who can also teach as an adjunct faculty member. We issue an account for the individual based on their name, so Joe Smith would get [email protected]. and it is up to them to sort through their mail for staff content versus adjunct content.
HR wants these individuals to have 2 accounts, one for their staff work and one for their adjunct work so the two are completely separated. One reason being that if the staff role is terminated for any reason, they shouldn't have access to their staff content, but could still continue in their adjunct role. Using the previous "Joe Smith" example they would keep their [email protected] account for staff work, and get the next iteration of our naming scheme as an additional [email protected] for their adjunct account.
I don't want to do this for a number of reasons:
- From a security perspective, I'd like 1 user to have 1 account
- It takes an extra email account license (we are using Zimbra)
- It's confusing to have two accounts that map to the same person for different roles
- In any case, the user has that content, and can do whatever they want with it: forward to their other account, save it to disk, whatever. So if HR has dreams of keeping any staff-only information from a user when their staff employment is terminated that is a pointless battle
Some options we have thought of:
- Create an alias and set up a persona in Zimbra - This solves the licensing issue and everything is in the same account, but is not separate in that if their staff employment is terminated they would still have access to all that stuff.
- Different domains - having [email protected] and [email protected] - This is still as crappy as the 2 account solution, now they are just spread across 2 domains
Has anyone else experienced a similar situation, and if so how did you deal with it?
I have recently been receiving spam that has been listed as my own email address. I remember doing a few telenet emails back in school and know there are some ways to send looking like they are coming from a different place but wanted to ask others opinions on this. The server is a Zimbra 6.06 server running on Debian lenny. Does anyone think there is possibly something wrong with the setup here or is this just some spoofing going on? I can see that the email is coming from outside of the network of course.

I really don't get (because of my ignorance, of course) the advantage of having another service to update, check, mantain, backup and so on... When you have outstanding services like gmail where you can pull the user official mailbox in. We have 40 users and any kind of "light" would be greatly appreciated :)
