People running their own email: do you use DMARC? What for? I added the DNS entry and now I'm getting sent reports which I don't read. That seems stupid. Do I just remove it again, or is there some secret magic I should be thinking of?

@kensanata the only reason i use it is to increase chances of getting outbound mail accepted. I never do anything with the reports either.

@mrb I wondered if I could get the same benefit by simply having the record without rua: no reports! Hm.

@kensanata @mrb If reports annoy you, just ignore or auto-delete them 😅

@jlelse Always an easy answer, of course. I might remove the DMARC record instead, however, since I still don't understand the benefit unless you're interested in the reports. So there must be a use case for the reports that's maybe only relevant for companies or something.@mrb

@kensanata @mrb I think enabling DMARC hasn't any cons except the few reports you get (but which you can auto-delete if you're not interested in them at all), but has probably a positive impact on reputation. It seems that even Google is excepting my mails with DKIM, SPF and DMARC after just a few conversations with Gmail users.

@jlelse What does "Google is excepting my mails with DKIM, SPF and DMARC after just a few conversations with Gmail users" mean, exactly? You had DKIM and SPF and Gmail marked your mails as spam some of the time and now it doesn't do it any more? Or are you just saying you have all three enabled and your mail gets delivered, but you don't know whether enabling DMARC made a difference?

@kensanata Yes, in the beginning Google rejected some mails. But now it seems to accept them. I read only about people complaining. that Google is rejecting their mails even after years.

@kensanata But it's just an assumption. DMARC is relatively low effort, so why not enable it when it can help improve reputation?

@kensanata I use the whole kit;SPF, DKIM, DMARCThe reports are not meant for you to manually to read but to parse them into readable formats.Also, if you are setting the policy to reject or quarantine - you are more then likely not able to participate in any mailing list. :/@jlelse

@selea Ah. One more reason mailing lists are dying, haha. I guess I don't mind because I don't participate in any.@jlelse

@kensanata Actually, there is solutions for that too ;)ARC is coming, which is going to solve that issue :PBtw, dont forget to send DMARC-reports yourself :)I wrote about how you can install opendmarc and make your mailserver compatible with it:https://blogs.linux.pizza/deploying-opendmarc-on-your-postfix-mailserverI have yet to add the section about how to start to send reports.@jlelse

@selea Hah, the point of my recent investigation into using migadu.com was exactly my wish to avoid hosting my own mailserver. 😃 @jlelse

@selea Just skimming that blog post, it would seem that there's maybe a comma missing in this line?non_smtpd_milters = inet:localhost:8891,inet:localhost:8893milter_default_action = accept

@kensanata @selea @jlelse perhaps better in another thread, but what is the hesitation to host own your email? Once configured I find it nearly maintenance free (i host for 20 people or so).I've never used the precooked solutions like mailcow(?) but they seem to make life easy for most people.

@mrb @selea @kensanata Yes, mailcow made it possible for me to setup my own mailserver in less than a day (jlelse.blog/thoughts/2019/mail-server/).

Switching away from Gmail to a new mail provider: the first thing I notice is that I get multiple spam mails a day, now. (The new email mailboxes have addresses over fifteen years old that just didn’t work for many years. But spammers remember.) Curious, I checked Gmail spam and found a few notifications by Blogspot – some containing spam and some falsely qualified as spam. You give some and you take some. I feel like I’m between a rock and a hard place. Perhaps I need to up the filter level.

Reporting from my Migadu mail experiment. I’m redirecting some old email addresses to the new account. I’ve set the spam filter strength to paranoid and spam still gets through. They use rspamd in the background. Hm. And today was the first day a Gmail user told me that they hadn’t received my mail and had only heard about it after receiving the reply from another Gmail user. Hm.https://alexschroeder.ch/wiki/2019-09-19_Spam#spam #mail
