There are a bunch domains that are incredibly sensitive to this kind of thing. Crank up the concurrent connections and search logs for "*connections*" You'll find the ones that care really quickly. There are plenty of them. On Fri, Sep 6, 2019 at 3:29 PM Blake Hudson via mailop wrote: > For what

For what it's worth, Oath is the only email service provider I've ever had to rate limit outgoing email to. All other email service providers seem to work fine when one uses the (seemingly sensible) Postfix defaults. Laura Atkins via mailop wrote on 9/6/2019 2:49 PM: Gmail has never suggested

Now people have made me curious what they set those values to for Gmail. We don't have simple limits like those (a quick check shows the max number of messages sent on a single connection in the past week is 414k, and I know I've seen total number of connections from a single source over 10k), the

Not short, but certainly sweet: I don't care what method people devise to make sure that people don't get added to a mailing list without their consent, so long as it actually works. I don't care if they call it "sucking chest wound" so long as the process they adopt effectively prevents abuse. Do

There were smaller folks who did tarpit heavily and there was likely badly written spamware, but neither of those were cases I was thinking about. I’m, basically, quoting one of the mail engineers from one of the large mailbox providers. They implemented limits to connections and limits to numb

I remember that IIRC a lot of that was down to the receiving mail server tar-pitting perceived spam connections to deter. However a lot of software was so crude it had no connection timeouts and just sat there - haven't seen that behaviour in a very long time :) On Fri, 6 Sep 2019 at 11:08, Laura

There was a point in time where if you didn’t limit the number of messages per session a few of the larger mailbox providers would simply cut you off. The issue was some spammers were making hundreds of connections and then holding them open for days (yes, really, more than 24 hours at a time).

Hi Alex, Yep we have been using roll up by MX since it became available and roll up by IP for all the hosted outlook vanity MX records which used to make IP warming a nightmare. Once Yahoo is back on it's feet I'll push ours back out to 20 Cheers Dave On Fri, 6 Sep 2019 at 09:00, Alex Irimia
