Today I received a notification *e-mail* after somebody has replied to a post:

https://forum.dlang.org/thread/jiefcxwqbjzqnmtazkwy@forum.dlang.org#post-sksbiiwnfsxocklwcfsd:40forum.dlang.org

I would greatly appreciate if the zone admin of dlang.org adds an SPF record
also to forum.dlang.org. At present there is none:

$ host -t txt forum.dlang.org
forum.dlang.org is an alias for dfeed.kimsufi.thecybershadow.net.
dfeed.kimsufi.thecybershadow.net descriptive text "google-site-verification=v0zp5IJgjZ-bfE4El8UEQwnHdNma3wwmU8JNvbzlVDY"

in contrast to

$ host -t txt dlang.org
dlang.org descriptive text "v=spf1 mx a ip4:205.201.128.0/20 ip4:198.2.128.0/18 ip4:205.201.134.0/24 -all"

That would help to reject unsolicited e-mail traffic from k3.1azy.net (k3.1azy.net [178.33.224.37]) and possibly others.

Hi,

SPF/DKIM/DMARC are good ideas in general (currently *.forum.dlang.org is CNAME'd to a single domain, so that would need to change first). But, do I understand correctly that the email you received was unexpected?

forum.dlang.org never sends out email unless you asked it to. In order to receive reply notification emails, one must create a forum account, post at least once, then, in settings, enable email notifications for the "Replies to your posts" subscription.

According to my records, your first post under that user account occurred on 2017-05-27, and you enabled the subscription on 2017-10-14. Is it possible that you've simply forgotten that you've done this?

In any case, if you no longer wish to receive emails, every email includes an unsubscribe link.

Hope this helps.

Vladimir!

Sure. And I also got a notification email of your reply:

Return-Path: <no-reply@forum.dlang.org>
Received: from k3.1azy.net (k3.1azy.net [178.33.224.37])
From: D Programming Language Forum <no-reply@forum.dlang.org>
Subject: Vladimir Panteleev replied to your post in the thread "SPF record for forum.dlang.org"

Is this host ligitimately sending out these notifications?

I stand corrected. Found the config in the settings area.

> Is it possible that you've simply forgotten that you've done this?

Well, yes. Because I have not yet gotten any of these notification until today.
I got no notification e.g. of this post

https://forum.dlang.org/thread/mutegviphsjwqzqfouhs@forum.dlang.org?page=2#post-fgfsezyxdzszmwniuizc:40forum.dlang.org

of 2018-01-11.

Yes, partly.

Yes. 178.33.224.37 is the IPv4 address of forum.dlang.org, and k3.1azy.net is the server hostname and reverse DNS hostname of 178.33.224.37.

As the text in notification emails mentions, the software will not send any more emails until all messages in the subscription have been viewed. At the time of that post, there were 9 unread messages in the subscription message queue. If there are any subscriptions with unread messages, the software will also show a notification on the front page (https://forum.dlang.org/).
