Mail and Console problems

rafaelzgz

Hi, I have two problems with my Flarum installation, hope you can help me.

The first one is related to emails. More specific with sing-up email, I´ve configured a self-hosted SMTP server. It´s a Postfix with Dovecot and Postfixadmin for virtual boxes. The e-mail server works perfectly well, I use it as my current mail, also when I send the test e-mail it´s working, but all the new users from my community reports they don´t receive the mail (Yes, they have also looked inside the spam folder). Here is the config from admin panel :

mail-config

My second problem is related with a console command, php flarum schedule:list , when I execute this command I obtain an error, this is the log:

flarum.ERROR: TypeError: DateTime::setTimezone(): Argument #1 ($timezone) must be of type DateTimeZone, string given in /.../flarum/vendor/illuminate/console/Scheduling/ScheduleListCommand.php:42

Stack trace:

#13 /.../flarum/flarum(24): Flarum\Console\Server->listen()
#14 {main}

I don't know if this is related, but in my php.ini I did set the TimeZone. Maybe the both problems have the same origin? No idea. If it matters I also set up the schedule cron job.

Wait for your suggestions and or support, thanks.

Kudos for operating your own mailserver! It's a pain in the ...! 😉

SMTP Banner Check: Reverse DNS does not match SMTP Banner

Your Server/IP is also listed on some Blackslists - including Spamhaus which is as far as i know widely used! That might be the main culprit! While looking up your mailservers IP 83.59.131.245 on Ripe, it looks like an IP from a pool for dynamic IPs from Telefonica Spain. Also not a best practice for a Mailserver.

To what did you set it? You can find the supported List of timezones here: https://www.php.net/manual/en/timezones.php
Be aware, there are usually two php.ini files. One for fpm and one for cli. Maybe you missed one.

Yes, maybe that's the problem with the emails, but I should say that some weeks ago it worked (I don't remember how long ago), and also, why did my personal account emails arrive but these ones not?

I set it up for other applications where this was needed. I changed it on all my php.ini configurations.

And thanks for your time.

Regarding Mail, the reasons are manifold, and in my experience never a clear "it works" or "doesn't work", but most often a "it works sometimes or in some cases"! Some of the reasons can be not using Blacklists on your SMTP. Allow-listed the domain. SPF-Score not reached. Or simply your personal account uses the same domain or same mailserver and therefore some mailserver-configurations omit a lot of checks.
Like always with Mail-problems there is no simple answer. You always have to figure it out yourself for your specific use-case. I can only offer you some hints. Maybe it's also worth looking at the following points:

check out Mailcow if you want to run your own Mailserver
run your Mailserver from a VPS with a static IP
check out one of the specialized services for sending mail like Mailjet/Pathwire, MailChimp or AWS Simple Email Service (SES)

wolfman The Flarum team can +1 on the Mailcow recommendation, it's what we use and it's domain setup guide helps a ton with making sure you have the base DNS records required for proper email sending. Most importantly with any email system you should properly implement:

SPF
DKIM
DMARC
Reverse DNS (IP DNS lookup resolves to the mail server hostname)

If your sending a large amount of email (more than like 100 a day) then I also highly recommend you find and register for all the major hosting providers feedback loops.

I find the feature with the suggested and current DNS-Records for the Mail-Domains extremely helpful! Like you said SPF/DKIM/DMARC/Reverse DNS make or break your mail-delivery.

Finally I have uninstalled my mail server completely and installed Mailcow 😅.
I already had the DNS-Records well, except PTR for Reverse DNS (can´t fix that because for now I should stay using a dynamic IP, in the future I´ll change this in other to use a static IP).

I still have the problem with the php flarum schedule:list command.

rafaelzgz The latter issue is probably the same thing causing our CI to fail:

https://github.com/flarum/core/runs/4750392246?check_suite_focus=true

We'll investigate this.

rafaelzgz Try running composer update and checking again. The recent Laravel release should fix this for you.

rafaelzgz

askvortsov Perfect! Thank u all.
