Re: DKIM Configuration

Having issues with DKIM failing after setting up on my Zimbra 8.7.11 Installation. I then used this guide: https://wiki.zimbra.com/wiki/Configuring_for_DKIM_Signing Not really knowing how to test, I would go back to that link and find the section where opendkim-testkey is mentioned. You should be a...

Re: Another Letsencrypt method

But i have 3 questions 1- acme.sh script only handles cert issue and renew? i see it added crontab job 31 0 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null , so the cert will renew every 30 days, but i have to install manually, copy to zimbra folder and...

Re: Generate DKIM: Domain not found?

Ok, this pretty much sums up our experience with Zimbra so far. It doesn't seem like it's at the stage where it can be taken seriously. Sorry to put it like that. We do hope it will improve in the coming years. Did you contact zimbra support? Unfortunately, these are volunteer forums from the user ...

Re: Generate DKIM: Domain not found?

Tried as you suggested, but it says that domain is not found. Here's the zimbra@sub:~$ /opt/zimbra/libexec/zmdkimkeyutil -a -d domain.com -S sub.domain.com Domain domain.com not found. I am not sure if I've ever been more confused about getting anything work in ubuntu more than having to deal with ...

Re: wiki.zimbra.com - typical documentation chaos?

It has always been a source of confusion for me. I have a paid support contract and support refers me to a wiki page to solve the issue. Here is a recent example... See this thread: https://forums.zimbra.org/viewtopic.php?f=15&t=64514 ... The wiki page they sent me was at https://wiki.zimbra.com...

Re: Generate DKIM: Domain not found?

zimbra@sub:~$ /opt/zimbra/libexec/zmdkimkeyutil -a -S sub.domain.com but it keeps giving us a list of usage rather than the dkim. Can you please give me an example how exactly should I put this domain to make a dkim for a subdomain? Have you tried... $ /opt/zimbra/libexec/zmdkimkeyutil -a -d domain...

U2F fido alliance

Does anyone know if Zimbra will support U2F or better yet FIDO 2 from the Fido alliance as one of the second factors at some point? I have a co-op student building us cheap u2f tokens for approx $4 each based on the u2fzero project and we are close to finished on the hardware side for her project. I...

Re: local and external servers
