XG stops reading SMTP Exception with the first hit. SMTP Exception are not combined.
I wanted to configure SMTP exceptions very granularly, when I started to configure SMTP exceptions in XG firewall.
Therefore, I made one exception for antispam, one exception for dkim, one exception for malware and so on. I soon recognized that this does not work. XG firewall searches the SMTP exceptions until it has the first hit. If I add the email address firstname.lastname@example.org to the antispam exception and to the dkim exception, only one of these exceptions work. I have to configure a new exception, which skips both, and have to add email@example.com there and have to delete firstname.lastname@example.org in all other exceptions. Took some time to analyse, test and realize.
I already created support case 03333733 but senior technical support engineer told me:
"This is normal behaviour ("XG firewall stops reading the exceptions with the first hit").
I would suggest anyway to check with your Account Manager the entire configuration of the exceptions
Please change this behaviour. XG should read all exceptions and cumulate the skip settings.
