Hello. I have a discourse without a docker on my local server. Also installed iRedMail. First I tried to use an smtp-server from mail.ru. Test messages were sent, as well as invitations. But no email notifications came in, and the password was reset. I decided that I should install my local mail server and see the logs there why messages do not leave. I did. Local messages come between mailboxes. That’s what you need for testing. Thought it would be enough for local discourse and mail. Set your local smtp server. Sent a test email… and it got there! Winner(no). Looked at /var/log/mail.log of the mail server. [image] Okay. Now I’m sending an invitation to the same box… Looking at the mail server logs… …and nothing. It’s empty. I don’t know what the problem is. All I’m asking is a “how-to” get discourse to speak to postfix. Right now I have an active admin account by manually enabling it cause, you guessed it, I didn’t get the verification email. I’ll provide any files such as settings and logs upon request.

Dear @Anv Welcome to Discourse Meta. Normally when we have these kind of problem we run something like: sendmail -vvv A_VALID_EMAIL_ADDRESS < email.txt and this will give you a very verbose output of the handshake between you and the SMTP server; and normally that verbose logging will provide you the clues to solve your issue. Hope this helps.

Hi! I don’t have much experience. Installed dicsourse and a mail server for the first time. Could you elaborate on what exactly I need to do? Thank you.

[image] Anv: Could you elaborate on what exactly I need to do? Hey @Anv First, you need to temporarily “forget” about Discourse, and focus on getting your SMTP mail relay up and running, tested and to make sure it can relay mail. Have you done that part already?

[image] neounix: Have you done that part already? I installed iRedMail using this link. [image] How to Easily Set Up a Full-Featured Mail Server on Ubuntu 22.04 with iRedMail This tutorial will be showing you how to use iRedMail to quickly set up a full-featured mail server on Ubuntu 22.04, saving you lots of time and headaches.

Hey @Anv That’s an advanced install for sure. Did you test it without discourse and insure it is working? Something like: sendmail -vvv A_VALID_EMAIL_ADDRESS < email.txt ?

I made 2 mailboxes in my local domain “@ugda.space”. And the messages are coming to each other. To gmail/mail/yandex boxes, the messages don’t reach each other. I didn’t set it up, because I thought I could have enough intra-local communication for the tests.

@Anv Let me be blunt: A good unwritten rule should be something like “don’t ask people to talk to you if you’re not willing to put the effort to listen to them”. By “listening”, I mean considering what they’re telling you. Participating to a forum counts as “asking people to talk to you”, I guess. Especially if you’re asking for help. Keeping on repeating the same thing, and forcing your interlocutor to also repeat himself doesn’t lead anywhere. For anyone. Now, why have you not run this command line already ?

Hey @Anv I understand your frustration; and I’m sorry I don’t have more free time to debug all your SMTP relay problem every time you reply. It seems like your SMTP mail host is receiving mail; but that does not necessarily mean it will work as an SMTP relay. I recall, off the top of my head, there is a flag to use sendmail and other mail clients to check if the SMTP host is working properly as a relay. You might do some research on the sendmail -G option (or look for another way to test). Basically, you need to send the mail to a test email address different than the host you are working on, using your newly minted SMTP host as a relay. Some History In the old days, most SMTP hosts would relay mail out-of-the-box; but then all the SMTP hosts on the net became big SPAM boxes because spammers would just exploit the relay functionality (unknown to the owner of the box) and spam the world. The bottom line is that you need to check to see if your newly minted SMTP host can relay the mail for you. Did you look closely at your configuration tutorial and see if it mentioned setting up the SMTP host as a relay? I’m just thinking out loud and hope this helps you in some small way get to the next step in your SMTP host project.

Okay, I think I hear you. I’m gonna see if I can find out any information on this.

Hi @neounix.

Anyway, thank you so much for helping me with this.

Perhaps my main problem is that I want to run this inside a LAN without access from an external network.
