Re: Zimbra outbound relay not informing bounces

Correct my friend.

I think Im going to handle it by creating a small software that listen to their bounces integrated with their api. This is all because there is a manager at the project that thinks google is the best ever and ever...

Thanks.

Zimbra outbound relay not informing bounces

Hello, First of all, thanks for your support. I recently had to migrate my Zimbra server to Google Cloud and by default they block all the outgoing email ports, so I´m forced to use Relay at my server. I choose mailjet to do the job and it's working ok, the only problem I´m having is to inform the s...

Re: Sending emails from non registered hosts

Hello friends, Just to not let this topic without explanation and in respect with the help provided. I notice that the relay system MailJet that Im using does not return if the message was bounced and somehow the bounced messages are being blocked to send me back the information, something very stra...

Best regards,

I would like to allow only localhost, but I don’t know if I should remove all these mta information.

Re: Sending emails from non registered hosts

It's quite possible you don't have a problem. My apologies for that info I posted about postfix, I can't really understand where I got it - it must be my advancing years and your output is what the command should show. Can you explain in a bit more detail what the my networks entry is showing, are ...

Re: Sending emails from non registered hosts

Have you had a look in the Zimbra log to see if any of these addresses appear there? Is it possible you have any compromised accounts? Does your ZimbraMtaMyNetworks contain the correct settings for your installation and nothing extraneous in there? Hello, In my zimbra.log I don't have anything abou...

Re: Sending emails from non registered hosts

Let's go back a step, you should always give the version of ZCS that's in use by posting the full output of the following command: zmcontrol -v Ok, my version is: Release 8.8.12.GA.3794.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.8.12_P1 proxy. I had that problem with the exploit´s one or two mon...

Re: Sending emails from non registered hosts

I don't really understand what you're describing, it sounds like you're allowing another server to relay through your server - is that correct? If it is then it sounds like you have an open relay, you can check that via one of the (many) sites on the internet that provide this service - I'd suggest...

Sending emails from non registered hosts

Hello, First of all, thanks for the help. Currently, I installed a relay system to get better management from my sent emails. One thing I notice is that my zimbra is sending from hosts that are not registered, is there any solution to avoid it? For example, Host test.com is sending email but is not ...
