In today’s email campaigns many receiving smtp servers will send out a deferred message or otherwise greylist a sending server to test if they are spam bots.
Does Mautic support the retry feature or is this always a function of the delivery agent such as Exim, Postfix, etc?
If it is a function of the delivery agent and we use an smtp server on our own domain which also hosts the Mautic server how would one setup the smtp login credentials for a local server?
I use phplist on other servers and it handles interaction with the localhost seamlessly. I’m a bit confused on how to get Mautic to talk to the local smtp instance for sending and if credentials must also be served. My confusion is because I am familiar with connecting to an external smtp server but everything I am speaking of above, is local.
Thank you in advance.
