I see that in the docs recommend to use dedicated mail service and all of the blog that show how to set up the SMTP mail, they always use the dedicated mail service like mailgun.
According to This
" We strongly recommend using a dedicated email service. Email server setup and maintenance is very difficult even for experienced system administrators, and getting any part of the complex required email setup wrong means your email won’t be delivered, or worse, delivered erratically."
Where can I find these difficult step?
Is there any board or any that show how to do it?
I want to use my own SMTP server, but totally new with this.
Thanks
Check out “Mail in a Box”. There is at least one topic here about it. I’ve not used it but one thing I remember is a lot of people recommend not to use Digital Ocean as they say it is a spammers’ paradise.
There are many ways to do that, but none recommended or supported here. You’re welcome to give it a go, but if what you want is a functioning server and not a month long project, I recommend starting with something that is likely to work.
But the short answer to the question in the title is “Google”. It’s a popular search engine on the internet.
Ah, in that case I’d think you can get it set up in an evening. If it’s low volume and you have a bit of patience for your mail classified as spam, it sounds like a great project!
And though I ran mail servers in the 1990s, I too have been using Mailgun for the last several years thinking that next week I’ll get a mail server set up.
