Hi Stefan,
Could you please explain a bit more the issue. I have been receiving flashrom mails just fine ( and I have free gmail account). Once on a while some of the e-mails would be marked as suspected spam. The most often this happens on mail originated from East Europe. Are we are talking about those e-mails, or entirely different issue?
Yes. Your and the subscriptions of all others directly addressed has been disabled because too many emails were not accepted by gmail. I am not 100% sure if that was just some kind of greylisting and gmail did accept the mails eventually, but it did report a permanent failure back to our mail server. This looks as follows:
SMTP error from remote mail server after end of data: host gmail-smtp-in.l.google.com [2a00:1450:4013:c00::1a]: 550-5.7.1 [2001:470:9f5b::25 12] Our system has detected that this message 550-5.7.1 is likely unsolicited mail. To reduce the amount of spam sent to 550-5.7.1 Gmail, this message has been blocked. Please visit 550-5.7.1 http://support.google.com/mail/bin/answer.py?hl=en&answer=188131 for 550 5.7.1 more information. s3si2581668wjx.75 - gsmtp
If mailman (the mailing list software) gets too many of those for a certain subscriber address then it automatically unsubscribes the recipient because it does expect this to be permanent.
There are some things we could change on the mail server to mitigate it as I wrote before, but it seems that nothing really works and it is rather a race between gmail demanding senders to jump through further hoops and the senders implementing that. I am not too familiar with mail and DNS servers though. If you want more technical details I can ask Patrick to respond.
The main reason I use GMail as my public e-mail address is exactly their spam filter. It is by far the most accurate of Hotmail, Yahoo or almost working e-mail service provided by my ISPs available to me.
Do you have any other recommendations for e-mail provider?!
One that allows to whitelist mailing lists manually for example ;)

Well, https://support.google.com/mail/answer/81126?hl=en suggests using the same IP's, having reverse DNS records set up, and also use something like DKIM. I can see by DNS lookup that you don't have a DKIM TXT record. DKIM would be my recommendation, rather than telling people they can't use Gmail.
John.

SPF and DKIM alone is not enough and even with DMARC (implemented for the coreboot.org ml some mails are still detected as spam according to patrick, although it already changes how mailing lists work...
I am not telling anybody not to use Gmail. I have just notified affected parties about possible consequences in doing so. If you take pleasure in configuring DNS and mail servers, drop Patrick a mail... I certainly don't. :)
And with that I'd like to stop spamming people directly. We can continue the discussion on-list if need be.
Thanks for the heads up Stefan, hopefully should be back on now.
