Here is my situation. I have been using Astaro to scan my emails that come through pop3 for a while now. It works great. But I need to have better control over spam so I told my hosting company to point both HostA and MX records to my static IP (external nic on Astaro). I enabled SMTP Proxy and set the HOST (MX) to mail.domain.com
I then told Astaro to allow relay from my internal mail server that is on my DMZ. (Created definition of my mail server in definitions - networks)
I wanted to use virus and spam scanning so I added a domain group for mail.domain.com
I then enabled spam and virus scanning with quarantine. my problem is I cant send email with my mail server unless I put a packet filter in
Mailserver -> any
Allow SMTP
I thought I don't need a packet filter with SMTP. Am I wrong?
Please can anybody help?
