Zimbra Mail Not Sending and Receiving – Solution

If you need to allow all other hosts or even the network to send mail through the MTA. Then add it to the relay list.

Note: Please be vigilant, any misfire will make it easy for malicious outsiders to send spam through your computer.

2 Step Solution to Fix Zimbra Outgoing Mail Issue

Follow the command based solution to fix Zimbra Mail not sending and receiving error:

Getting Existing Value

First, run the following command on your MTA server

su – zimbra
prov gs ‘hostname’ | grep zimbraMtaMyNetwork

If nothing is restored, you are only using the default suffix. Therefore, first use the following command to get it:

su- zimbra
postconf – d mynetworks

Setting New Value

To add a host, simply use the following method to add an existing value:

su – zimbra
zmprove ms ‘hostname’ zimbraMtaMyNetwork “127.0.0.0/8 10.1.0.0/16 a.b.c.0/24 w.x.y.z/32”

The above quote is very critical:

When specifying an address range, it is important to always use the initial address range. Therefore, 10.1.0.0/16 is valid because the address block of 10.1.0.0/16 starts at 10.1.0.0. However, it is not 10.1.128.0/16 because it is not the beginning of the block range 10.1.0.0 to 10.1.255.255.

Now restart all services when you are done.
