I was looking through the documentation about email for may 1st (About email at May First | Help), but couldn’t find anything about sending emails via SMTP, for example from a local e-mail client.
Is it possible, and what are the necessary SMTP configurations (port and domain)?
It looks like the post here disagrees with the linked Help page: the post here says the account is the yourusername@mail.mayfirst.org, while the Help page says you only use: YOURUSERNAME. Would either work, or did something change, and only one or the other is correct?
Also, I’ve got a related question that I wasn’t sure whether to reply here, or start a new thread:
How do we modify these instructions to work with our own custom domain?
I can start a new thread if that would be a better place for this question.
Oh - your are right. The correct answer is just USERNAME. In some places USERNAME@mail.mayfirst.org might also work but you should always use just the USERNAME when logging into email to ensure it works consistently everywhere.
And, your own custom domain should not be used for authentication at all. Just the username when logging in.
One last possible point of confusion: when using Thunderbird and other email programs, sometimes you are only asked for your email address to auto detect your mail settings. In that case, using USERNAME@mail.mayfirst.org (regardless of whether or not you have a custom domain name) will allow the program to auto detect the right settings, using mail.mayfirst.org as the server and USERNAME to log you in.
