Troubles understanding Message delivery flows #41

Closed enekux closed 7 years ago

enekux commented 8 years ago

Hi,

I have troubles understanding the Message delivery flows.

Our Postfix server is used as a "Gateway/AntiSpam-AntiVirus Filter" mail server for multiple domains for Incoming and Outgoing mail flows.

But I don't quite understand the statistics shown under Messaging/Message delivery flows:

External -> Internal External -> External Internal -> Internal Internal -> External

I have been playing with next directives to make some sense, but still I don't understand the results:

LOCAL_DOMAIN domain.com, domain2.com MAIL_HUB 127.0.0.1,::1,mail.domain.com, mail.domain2.com MAIL_GW

Would this be ok?

What is the interpretation for:

External -> External Internal -> Internal

Thank you and regards

Hi,

Sorry for the response delay. Here you only need to set the list of your internal domain in the LOCAL_DOMAIN configuration directive. MAIL_HUB and MAIL_GW must be empty.

Regards,

Hi,

ok I will give it a try, do some tests and let you know.

Meantime, could you explain which emails fall in the Mail Flows:

External -> External Internal -> Internal

Thanks

You might not have External -> External flow, this can result of backscatting or bounced messages. Internal -> Internal is when your MTA is used from and to legit users. To simplify you can see External as Internet and Internal as your private network.

I've also configured LOCAL_DOMAIN but External->Internal is 0 0.00 0.00%. Thanks

p.s. i've installed sendmailanalyzer master and commit dd038624d391b4625da52fcf3cc962d049a1e79e
