I just got an email to send out finally. When sending to this one test address on Comcast's systems, it only went through after I upped the SMTP delay:
(Curiously, the email WAS going through before I upped that delay from 5 or 10 seconds, but the SMTP process was reporting an error back.)
Here is a snippet of the debug logs after I increased the timeout setting:
CLIENT -> SERVER: EHLO santiamwine.com
CLIENT -> SERVER: AUTH LOGIN
CLIENT -> SERVER: MAIL FROM:<firstname.lastname@example.org>
CLIENT -> SERVER: RCPT TO:<email@example.com>
CLIENT -> SERVER: DATA
CLIENT -> SERVER: From: Abc <firstname.lastname@example.org>
CLIENT -> SERVER: Subject: Test Sending
CLIENT -> SERVER: Bounces-To: email@example.com
CLIENT -> SERVER: List-Owner: <mailto:firstname.lastname@example.org>
I have a few questions:
Is it possible to get the 'Mail From' value to match the 'From' value? Wouldn't this help make it more anti-spam robust?
Is there a way to alter the 'List-Owner' value? It does show up in the email headers on the receiver's end - probably not a huge deal, but I'd like to keep various pieces of the email headers as coordinated as possible to prevent possible spam flagging. I have the 'Use Admin details...' setting turned off:
I'd like to either exclude that value altogether (not exactly sure what purpose it provides) or set it to be a system address. The current address 'email@example.com' is my email, which is only configured as the 'system owner' email.
