Straightforward direct-delivery incoming mail

pfaffman · April 5, 2019, 11:56pm

Hey, @JoshuaJoma. I’ve got a configuration that modifies the mail receiver to use the let’s encrypt certs that app.yml generates and maintains. It’s now standard on my installs. If you already have a working Standard Install, I’ll install the mail receiver for $150–Incoming Mail Server – Literate Computing, LLC.

Hey, @mpalmer. Would you be interested in a PR? It’s just opening up ports 465 & 587, adding the let’s encrypt volume, and adding some POSTCONF_smtpd_XXX lines to tell postgres to use the certs.

I think it’s mostly safe to assume (or enforce) that anyone who has the wherewithal to install the mail receiver also can enable let’s encrypt, though adding a mail-receiver-no-certs template might make sense.

I’ve done everything in the book. mxtoolbox.com detects dns (shows DNS Record Published DNS Record found ) . but no mail reaches recieved /bounced folder. What did I do wrong?
I set it as DISCOURSE_MAIL_ENDPOINT:
http://myforumdomain.com/admin/email/handle_mail

Where to do it???

It’s hard to know what you did wrong without knowing anything about what you did right? You claim to have done “everything in the book”, but what book did you use?

So you installed the incoming mail server?

Can you telnet to port 25 from localhost? (that would indicate that it’s probably working)

Can you telnet to it remotely? If you can connect from localhost but cannot remotely, then something is blocking incoming port 25. If that’s the case, then you can start to troubleshoot whether it’s a firewall managed by the operating system or whatever your hosting environment it.

What does ./launcher logs mail-receiver say?

Can you share your actual host name so that we could check those things?

Thanks I read the topic and it turned out that I need to enable port 25 on the server and change the address in the mail-receiver settings from http to https. And now it works (perhaps…).

Nevertheless I don’t know if it works well. Here I created a separate topic with my question —>>>

jomaxro · April 11, 2019, 5:04pm

Heads up @eextra, an API key is in your log output. You’re going to want to revoke that key.

mpalmer · April 12, 2019, 6:48am

Yep, I’d take a look at a PR to add STARTTLS support. There’s no point opening up 465 and 587 though; they’re not used for receiving mail.

eextra · April 12, 2019, 7:19am

What does PR mean ?
Do I have to open 465 and 587 ports on my hosting?

Thanks for the information.

By the way. If someone gets such API code it can do harmful things on the forum or hosting ? What kind of things can these be?

itsbhanusharma · April 12, 2019, 8:38am

PR means Pull request.

You don’t have to

eextra · April 12, 2019, 8:42am

Well, then, where am I supposed to add STARTTLS support ?

itsbhanusharma · April 12, 2019, 8:43am

It’s not yet present in the system so You should wait until someone has added that to the mail-receiver system. Once that’s added, you’ll have to rebuild using the updated image and everything will work as expected.

jomaxro · April 12, 2019, 12:17pm

It depends on the type of API key. Assuming it’s a system API key, they can do anything they want within Discourse, just as if they had admin permissions on your site.

eextra · April 12, 2019, 1:33pm

If it comes to this that someone has my api key and does or has already done something on the site, can I check it somewhere what he did and when? For example, in some logs ?

What if he did something harmful and then deleted the logs (if possible) ?

Stephen · April 12, 2019, 1:38pm

Go to your admin settings, scroll down to API and revoke it.

With that key they can destroy pretty much everything.

Yes they could have technically already done damage, this is why you should take care never to share them under any circumstances.

jomaxro · April 12, 2019, 1:43pm

An API key does not give server level access, so the logs could not be modified. Any action taken that normally results in a log would still be logged when using an API key. Any other action can be seen upon inspection of the site, for example if the key was used to edit a post, you’d see the edit icon like usual. If a topic was created, you’d see it just as if it was created normally.

I wouldn’t be too worried here, revoke the key, review the staff logs, check that there aren’t any new staff accounts, and remember to check for API keys (and passwords, etc.) in logs when sharing them.

pfaffman · April 12, 2019, 4:06pm

Doh! The last SMTP RFC I was familiar with was 822. I guess it was failing for some other reason (DNS, I guess) and it was coincidence that it started working when I opened those ports.

// email / test To: shows that prop.ltcmp.net passes the tests with only port 25. (For a little while until I delete it. . . )

Here ya go! The TLS stuff is included but commented out.

neutralTTY · April 12, 2019, 11:31pm

Hi, I have a small question. If I setup that way. Change the MX records. Will I broke the webmail features with my domain?

Example: mymail@domain.com will still working with my webmail?

Thank you

michaeld · April 12, 2019, 11:31pm

Yes, you will break it.
You would need to use a subdomain like forum.yourdomain.com.

eextra · April 13, 2019, 7:06am

Thanks a lot. These are important things.

And what if i wanted to browse and analyze independent logs on the server . For example, the whole container ? Hwo to do it ?

It’s just how simple the tools are for that. For a rather beginner administrator ?
