Re: Some clarifications about DoS Filter: block IPs after a number of failed login attempts

Hi, As far as I understand...and please understand that I might be wrong, this is how it goes: 1. Is this a fail2ban-like implementation? If not, how does it work? Does it involve iptables rules? --> No, it is not a fail2ban-like implementation. It works at an application level and it does not invol...

Re: SMIME: Import users certificate to contacts from signed email

Hi, The video you refer, does this: 1. userA sends signed email to userB (2:10) 2. userA imports userB public key manually (3:10) 3. userA sends encripted email to userB (3:30) As you can see there, they do it manually. What they should have show is userB sending and encrypted email to userA after r...

Re: Migrate 7.1.3 to 8.8.12 open source

Zextras would be the way to go if you ask me in terms of "best way to migrate".

Regarding that error, i wouldn't know. Did you try also asking in zextras forums?

Re: SMIME: Import users certificate to contacts from signed email

I don't use it, so is couldn't tell how it works for me, sorry.

What I do remember is that public key exchange being automatic, once you exchange signed mails. Reviewing the info, I found this where it says something about being automatic https://www.zimbra.com/email-server-sof ... ncryption/

Re: Is there not an easier way to import another users certificate into your address book to send encrypted email?

Hi, Unless I'm mistaken, Zimbra is supposed to import the public key to the user in the contact lists automatically. So maybe you need to create the contact so it automatically saves the public key? I remember just needing to exchange mails signed to have the public key from others and give my publi...

Re: Change helo name and banner

It is safe yes. Quite a few configurations migrated from local configs (zmlocalconfig) to ldap ones, and these are 2 of them. So you may want to check the "configuration guide" under Zimbra Documentation page, that will let you search the "old" attribute. The desc command let's y...

Run these two commands and verify if this is what you are looking for.
zmprov desc -a zimbraMtaSmtpdBanner
zmprov desc -a zimbraMtaMyHostname

Re: Update Url Working?

Ohh ok. So the "too early" is meant to not overwhelm their servers with continous version check requests. Good to know, I wasn't aware of that! Thank you!!! Regarding the repos, for upgrading versions (major or minor), they don't work as you will still need to deploy from binaries. For pat...

Re: CVE-2019-9670 being actively exploited

Hi halfgaar,

This thing of the check versions not working was reported here viewtopic.php?f=15&t=66011&p=289875#p289875 by CarlCox. Do you think it may be related to this exploit? It seems to me that is just another bug.
