    Default Mail stuck in mail queue

    I'm running ZCS
    Code:
    Release 5.0.10_GA_2638.DEBIAN4.0 DEBIAN4.0 FOSS edition
    associated with a subdomain of my company and, until a couple of days ago, e-mails were correctly delivered.
    Now, I can see 13 mails stuck in the mail queue (deferred), which means that mails arrive on my machine but Zimbra cannot deliver them into the right mailbox
    From Zimbra, I can send e-mails, but nobody can receive.
    Can you help me?

    Update:
    problems started when I changed my servername via zmsetservername, in order to reflect the dns name (e.g. I changed Zimbra's machine name from debsrv2.dev-mydomain.com to dev.mydomain.com).
    I did not regenerate certs, but I could access zimbra from everywhere, allowing connection when my browser noticed that there was a problem.
    My question is: what do I have to do in order to make Zimbra work when I change my servername? (yes, I want to change it: otherwise, everytime I want to check e-mail folders from zimbraAdmin I have to manually change the URL in my address bar; stupid thing, but it annoyes me)
    Thanks!

    Have you modified your MX record to point to new name of the server?
    Have you put an correct entry for servername and its correct ip address in /etc/hosts file?

    My MX record points is not a problem, because nameservers are external (i.e. my MX record points to an A record that's bind to a static IP address, that is not changed).
    Neither the LAN address of the machine is changed (it's 10.0.0.11) and my /etc/hosts looks like this (assumed that "machinename" is the name of the machine zimbra is running and "my.new.address" is the A name of the DNS and my server name (set via zmsetservername))
    127.0.0.1 localhost.localdomain localhost
    10.0.0.11 my.old.machinename machinename my.new.address
    I have tried putting "my.new.address" near to localhost (bind to 127.0.0.1), but no way

    Modifing hosts file like this might help:

    127.0.0.1 localhost.localdomain localhost
    10.0.0.11 my.new.address mynewhostname
    10.0.0.11 my.old.machinename machinename

    I had tried, but /var/log/zimbra.log continuously said "Timeout while connecting to my.new.address" (even after restarting Zimbra).
    (I don't remember what was the exact error message, but I do not have all-week access to Zimbra's machine, sorry)
    BTW, thanks for helping me - I know it's a not-so-important problem

    if you could post the following it would *really* help us
    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    dig yourdomainname mx
    dig yourfqdnservername
    host `hostname` <- note backticks and not double quotes
    it is okay to obscure your domain name if you wish but please leave everything else intact.
