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

  • Hello there,

    Adding to what Raphael has mentioned, make sure:

    1)  IMAP/IMAPS/POP3/POP3S are selected in the automatic MTA rule, and SMTP/SMTPS is disabled.

    2) You have distributed the CA of the appliance to the devices 

    3) Make sure you click SAVE after checking the boxes mentioned above

    IF the issue persists at this point:

    4) Try deleting the automatic MTA rule and creating a new Firewall rule also with IMAP/IMAPS/POP3/POP3S

    If the issue continues, please open a case with Support and share the Case ID with us; if you are a Home user or don't have a valid license, please enable Support Access in your device and share the Access ID with Rap and me via PM
