To piggy back a bit on what has been said already... When it comes to gmail. every new "sending resource" requires a new warm up. From what I have gathered, a "sending resource" is (non-exhaustively) a new IP address, new SPF domain, or new DKIM domain. We send a lot of mail from a wide variety o

Hi Robert, I'm one of the developers of Haraka. verify=FAIL simply means that the TLS certificate presented by the peer host could not be verified as trusted by a CA. In the case of an MUA (which this appears to be), it would be normal as an MUA does not usually present client TLS certificates

If the server is saying your client connection is verify=FAIL/NO, I would imagine that means either you have a client certificate that doesn't verify, or you don't have a client certificate the remote server is being pedantic about it. Brandon On Wed, Apr 13, 2016 at 2:56 PM, Robert Guthrie wrot

Re: [mailop] How long does an IP address take to "Warm up"?

I take the rule of thumb that hotmail/outlook.com does not like more than 20% volume changes day over day and week over week. Subscribe to the SNDS, and if you see your IPs in the yellow, stop ramping up. All the other mailbox providers follow same rules more or less, but this gives you a fair cont

Yes, I need details to be able to investigate. Yes, some throttles apply to netblocks, but I should point out that throttles are not "just" a netblock or "just" an IP or domain, we have hundreds of different throttles depending on many features, and good enough reputation will exempt you from most

We don't just run reputation on IP addresses, the spammer killed the reputation of any associated domains and such. Your domain is recovering, but it can take up to 30 days to fully recover sometimes longer if people don't mark your mail as not spam. Though, that's only for the domain you're

And it is not only to Google, many other mail receivers requires SPF or DKIM over IPv6. And if you set up a mail receiver with IPv6, do these requirements too, it is an industry best practice (cf M3AAWG.org). On Wed, Apr 13, 2016 at 2:59 AM, Tony Finch wrote: > Thomas Wilhelm wrote: > > > > Do

Re: [mailop] How long does an IP address take to "Warm up"?

Hi Robert, Gmail's systems are very sensitive to sudden changes. Start with just a few/tens of emails the first day and ramp up slowly -- an *order of magnitude* at a time. Eventually their machine learning systems will discover that recipients want your mail and adjust accordingly. Paul On Wed,

Re: [mailop] How long does an IP address take to "Warm up"?

The very rough thought is that it takes about four weeks to warm up a new IP address. In your case, I think you'd want to split the traffic 50/50 between the old IP address and new one and then it'd be a case of waiting to see how long before Gmail figured out that the mail coming from the new IP a

Re: [mailop] How long does an IP address take to "Warm up"?

In general IP warming can take anywhere from weeks to months, depending on volume and other factors. Make sure you interpret Google’s replies based on the text, not just the status code. Quota errors have status 4XX and they have throttling at mailbox level and at sender level. The error may a
