IMAP/POP Scans and Relaying

Hello,

In the UTM world I was able to set up the UTM to relay all outbound email through it before going out.

Likewise, I was able to set it up to scan and mark all incoming mail for AV and SPAM and store for release by user via a weekly digest email or from Portal.

In XG, I see the digest option which I configured and test successfully, however when I set up the scan options according to the help:

https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Email/HowToArticles/EmailConfigurePOPIMAPScan/index.html

My incoming email doesn't make it unless I disable the auto-created MTA rule.  I can see this rule as 'accept' in the Log Viewer under Firewall but do not see anything logged under Email => Mail Spool and Mail Log.

With the UTM I could see all email traffic going in/out in similar spool and log screens.

Lastly, am I able to relay all internal email thru XG before sending out?  Again, I could do this in UTM.

Can someone tell me what I am missing?  Is the XG capable of this functionality like UTM was or will it only handle an internal email server?

Thanks,

Kerry

  • Raphael,

    Thanks for the reply.

    Sender does not receive anything with FW rule enabled.

    tail -f  /log/smtpd_main.log displays the following:

    21601 1 queue-runner process running
    21601 1 queue-runner process running
    21601 1 queue-runner process running
    21601 1 queue-runner process running
    21601 1 queue-runner process running

    21601 1 queue-runner process running

    The link you provide appears to be for my own mail server in the cloud as it requires MX record change which I cannot do as it is my ISP's mail server.

    I would like to relay any mail from inside my network from the XG firewall to the internet.  I also would like to scan for spam and AV any emails coming into my network via the FW first.  We use 3 different email services, local ISP, Google and Proton Mail.
