Is my understanding on SMTP Relay with Anonymous sending option correct?
I was asked to meet with IT architect team to advise on the configuration of SMTP Relay sendmail(Linux) with anonymous sending option.
I have little to none knowledge in this area and i've been doing some research online for the past 1 day. I would like people to correct me if i have the wrong understanding before presenting to everyone.
I am a developer in a project and we all have our Production environment which we want to have SMTP Mail Relay that can send anonymous email whenever there is a ETL flow failure. I've contacted the necessary party on the configuration of ETL scheduler but we are facing error when trying with sendmail command in linux.
After checking with my project IT Team, it is due to IP address of application servers are not whitelisted. We have requested to whitelist those IP.
Things needed from us(Goal) 1) Require IT team to whitelist our 3 environment meta compute IP 2) Port 25(SMTP) must be opened between the relay host and the mailbox host 3) Must be able to sendmail to corporate domain atleast Anonymous sending option: Can be sent without proper email? Or must be sent by a valid email from the corporate? Say if the company is TOMSHOES. I will need to set the sender as admin@TOMSHOES.com? Must I also provide password for it?
However, I need to know if there is anything else for me to prepare before meeting them? Am i missing some other configuration info?
