Hello
I have already rais emy issue in this topic but I didn’t received any answer
Myy problem is that for most of we-site I ave a double identification and all mail appear in mail box or spam, after 30 minutes. So I am not able to connect on various important account.
It is really annoying.
wild guess - if it’s not up to the service and murena runs rspamd in their config with greylisting not disabled, the 2FA mails spam score trigger its greylist action threshold.
If you’re a paying subscriber you can ask if the delay is higher than the default 5min timeout.
But… if the sending smtp will do retries after 30min it doesn’t matter - the initial greylist (“temporary reject” in plain terms) will delay it to the retry interval of the sending server.
Also, greylisting can sometimes be bypassed, when the login website offers a “retry” function (something like “I didn’t receive the email, please send another”).
this advice is 10 years old by now, but one prominent proponent of greylisting (Heinlein) says you need to hold onto the once-whitelisted triples ( client_ip / sender / recipient ) long term - that is postgreys implementation.
Rspamd will do greylisting based on spam score without permanent (as in days to weeks) whitelist it seems. That is bad for 2FA mails that repeatedly score higher than the spam threshold.
I never activated greylisting so can’t speak from experience, but in murenas shoes I’d subcribe to a spamhaus whitelist that skips the rspamd greylisting.
I continued to poke at the delay with a 2FA service (pcloud) that was previously greylisted. It scored lower on BAYES_SPAM after multiple deliveries/days - despite being the same content.
In my case, Bayes was the single deciding factor putting a mail over the threshold for greylisting. Not sure if I as a user take part in training the model (by moving mail out of spam) or if it’s global.
frankly I doubt this is related? Rainloops Filters map to Sieve, a step which comes after rspamd and the bayes stuff. I just think the scoring received some beneficial tuning for all users
