Zimbra not affected by log4j (CVE-2021-44228)
After intensive review and testing, Zimbra Development determined that the 0-day exploit vulnerability for log4j (CVE-2021-44228) does not affect the current Supported Zimbra versions (9.0.0 & 8.8.15). Zimbra Collaboration Server currently uses log4j1 version 1.2.16 which doesn't contain the lookup expression feature that is found within versions 2.0 to 2.17, which is the cause of the vulnerability. Also, Redhat (CVE-2021-4104) vulnerability does not affect the Zimbra Collaboration Server version (8.8.15 & 9.0.0). For this vulnerability to affect the server, it needs JMSAppender, which the ZCS Server does not use, and the ability to append configuration files.

Migration from iredmail to zimbra using script problem

Postby izadi60 » Mon Dec 20, 2021 8:30 am

Hi Dear friends
I want to migrate from iredmail to zimbra zcs-8.8.15_GA_3953 on centos 8 and I used https://wiki.zimbra.com/wiki/Maildir_to_zmmailbox_with_bash .(I made a little changes).
first I synced data to new server backup directory and then run the script. all the emails have been imported. because the data is huge (about 3T)during the rsync and importing old server is up and new emails received.
for last step the new server is up and rsync for syncing all last new mails to backup folder. when I ran script to import new emails all last emails will be imported again and there were duplicated emails in user's accounts.
Do you have any suggestion for this problem?
is there any option in zmmailbox command to not import same messages ?
or there is a solution to rsync delete same messages in destination?
Thanks in advance

Hello,

I think that Imapsync would be a better option for you: https://imapsync.lamiral.info/
