Re: Installing Zimbra the right way? (not being blacklisted)

https://sendersupport.olc.protection.outlook.com/snds/ Register your ip's with them. Every big provider seems to have their own hoops and this is what outlook/hotmail/etc required at one time. Another option is to stop playing the game and all the hoops the big mail operators require and use one as ...

Re: PDFs (with fill-able-fields) - Considered Encrypted PDFs...

David, I have not run into this specific problem you mentioned but we ran into a problem with fp's and that yara rule with new cell contracts sent by a mobile carrier a few years back - ie) t-mobile. My solution was to disable clamav from blocking encrypted pdf's but score them with SA instead. We n...

Re: zmlogswatchctl fail after OS update

I found that the /opt/zimbra/log/zmlogswatch.out contains an error "RRDs.c: loadable library and perl binaries are mismatched (got handshake key 0xdb00080, needed 0xde00080)". Wild guess. That message generally means A dynamic library .so was being loaded into the process that was built a...

Re: DKIM not add key on outbound mail

It runs as a milter I believe. Is /opt/zimbra/conf/opendkim.conf present? Does it look sane for your environment? What about master.cf? Do you see the DKIM entry. What about amavisd.conf? Is DKIM verification enabled? Ref: https://wiki.zimbra.com/wiki/Configuring_for_DKIM_Signing Generally it is fai...

Re: DKIM not add key on outbound mail

Unless you removed your entry, it doesn't appear to be published via DNS from where I am. You can pull your txt record yourself and compare against what zimbra generated for you or use something like https://dkimcore.org/c/keycheck to track this down. I would start with making sure DNS looks good fo...

Re: Organization Validated (OV) Certificate for 2 domain

Which type of certificate is easy to manage, install and not complex? What is the advantage and disadvantage of OV and Multi-SAN Certificate?

Re: Bug with firefox rendering some emails on 8.8.15 P16

This was reported and is being tracked as ZBUG-1998 Did you get any feedback on this bug so far? Never. Not a peep. I had forgotten about this and noticed my email was readable again and thought it was a firefox update. I asked our developer this morning about the status of this and here is what sh...

Re: Another Letsencrypt method

It doesn't appear we have to do anything and they have backed off Jan 11 switch and have found a novel method to continue to support old android clients. Nutshell: A new intermediate will indirectly sign the current Let’s Encrypt intermediate certificate (R3). This ensures that clients that know the...

Re: Routing Emails from internal domain to external domain

Two ways...

1) you have a blank transport file you postmapped so no lookup matches
2) you remove the transport file location and only use the ldap entry
ie) zmprov ms `zmhostname` zimbraMtaTransportMaps 'proxy:ldap:/opt/zimbra/conf/ldap-transport.cf'

Re: Another Letsencrypt method

With letsencrypt signing their own certificates beginning Jan 11, here is a link to a new feature that was added for acme.sh to support the preferred chain should anyone need to revert back to IdentTrust intermediate signed (very old android clients) or test early with the ISRG Root X1 signed before...
