UTM: SMTP Exception on FROM level (AMAZON AWS issue)
SOPHOS UTM Mail Protection gives the option for crating exceptions on Email Address / Domain, IP or recipient.
The Email Address which is used for white listening is the ENVELOPE header in the email.
We have the problem, that we have an service, which use Amazon AWS for sending mails. This mails run into the quarantine.
To whitelist, we need to whitelist die AMAZON AWS Envelope domain, which are for all AWS services the same.
Please create an option to choose the header flag – ENVELOPE or FROM field.
