Zimbra redirect webmail http to https

August 9, 2019

by ServerOk with No Comment Mail

After Zimbra mail server installed, webmail work on url

https://SERVER-HOSTNAME-HERE/

If you access webmail with out HTTPS, it won’t work.

To set HTTP to redirect to HTTPS, login to server as root, switch to user zimbra

su - zimbra

1	su - zimbra

Run

zmprov ms SERVER_HOSTNAME_HERE zimbraReverseProxyMailMode redirect

1	zmprov ms SERVER_HOSTNAME_HERE zimbraReverseProxyMailMode redirect

Wait few minutes, HTTP link will redirect to HTTPS.

You need to wait few minutes before it can start working on HTTPS port, no restart required.

Now netstat shows nginx runs on port 80

August 9, 2019

by ServerOk with No Comment Mail

To install SSL certificate for Zimbra Mail Server, login to server, switch to user zimbra

su - zimbra

1	su - zimbra

Now create file commercial.key, paste your Private key.

vi /opt/zimbra/ssl/zimbra/commercial/commercial.key

1	vi /opt/zimbra/ssl/zimbra/commercial/commercial.key

In commercial.crt, paste your SSL certificate.

vi /opt/zimbra/ssl/zimbra/commercial/commercial.crt

1	vi /opt/zimbra/ssl/zimbra/commercial/commercial.crt

Create commercial_ca.crt with content of your ca-bundle file.

vi /opt/zimbra/ssl/zimbra/commercial/commercial_ca.crt

1	vi /opt/zimbra/ssl/zimbra/commercial/commercial_ca.crt

Verify SSL cerificate

/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key  /opt/zimbra/ssl/zimbra/commercial/commercial.crt

1	/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key /opt/zimbra/ssl/zimbra/commercial/commercial.crt

If SSL verified sucessfully, you can install it with command

/opt/zimbra/bin/zmcertmgr deploycrt comm  /opt/zimbra/ssl/zimbra/commercial/commercial.crt /opt/zimbra/ssl/zimbra/commercial/commercial_ca.crt

1	/opt/zimbra/bin/zmcertmgr deploycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.crt /opt/zimbra/ssl/zimbra/commercial/commercial_ca.crt

To make SSL active, you need to restart Zimbra mail server with command

zmcontrol restart

1	zmcontrol restart

DMARC

July 11, 2019

by ServerOk with No Comment Mail

DMARC is used to protect your email from email spoofing. DMARC use SPF and DKIM record to validate your email.

DMARC is a TXT record added in your domain DNS.

DMARC record look like

v=DMARC1;p=POLICY_HERE;pct=100;rua=mailto:postmaster@your-domain.com;ruf=mailto:admin@your-domain.com;rf=afrf

1	v=DMARC1;p=POLICY_HERE;pct=100;rua=mailto:postmaster@your-domain.com;ruf=mailto:admin@your-domain.com;rf=afrf

p=POLICY_HERE

This specifies what to do with incoming email that fails DMARC.

Valid options are none, quarantine and reject.

p=none – used for monitoring. If DMARC fails, remote mail server will sent a mail to “rua” or “ruf” tags specified in DMARC record.

p=quarantine – tell recipient mail server to put message in SPAM folder if DMARC fail.

p=reject – reject mail if DMARC fail.

rf=afrf – Specify type of report you will get.

Zimbra Unable to validate certificate chain

On installing SSL on Zimbra mail server, i get following error

zimbra@zim:~/boby$

This was due to SSL cert chain. The ca-bundle file they provided did not work with Zimbra. This is due to some issue with the order in witch CA Certificate files are placed. Here is zimba documentaion related to this issue

https://wiki.zimbra.com/wiki/Fix_depth_lookup:unable_to_get_issuer_certificate

I checked with SSL provider, they initially provided a combined SSL certificate, that have cert file + ca certificate. I tried to install it, but it did not work.

After showing SSL support the screenshot of the SSL install page, they provided me with 3 differnt files.

In the zimbra SSL install, you have option to add more intermediate CA by clicking “Add Intermediate CA” link.

The provided files are

root.ca
intermediate1.ca-bundle
intermediate2.ca-bundle

root.ca

intermediate1.ca-bundle

intermediate2.ca-bundle

I tried to install it using UI, but it failed with some error related to RemoteManager and port 22.

To install on Command line, first you need to login as user zimbra

su - zimbra

1	su - zimbra

I copied all files provided by SSL provider to the server. Change to SSL folder

cd /opt/zimbra/ssl/zimbra/commercial/

1	cd /opt/zimbra/ssl/zimbra/commercial/

Edited the file

vi commercial.crt

1	vi commercial.crt

Pasted the SSL certificate content to this file. commercial.key file have the private key, this get auto generated during the CSR generation process.

Now i tried mixing those 3 files (CA certs) to create commerical_ca.crt, but it failed to work
