For anyone still following these issues it looks like Yahoo have reconfigured their mail acceptance policies over night and the response message has changed to indicate a substantial change in the rate they accept mail - this may catch a few out. entered backoff mode due to "421 Max message per co

Re: [mailop] Resolving issues for several yahoo domains?

That’s changed over the years, and depends on using IPv4/IPv6 and a few other details. There are also a few layers of control to make things more complicated. I would imagine most ISPs are like this, hence it seems like it would be easier to try to manage the number of messages per session tha

Re: [mailop] Resolving issues for several yahoo domains?

No, it's truly (at least for us) because some other ISPs literally do complain if we try to send too many messages per session.lots of people do things so many different ways. I can't find the ticket at the moment, but I even had one of those just a week ago, where the bounce message from some

Re: [mailop] Resolving issues for several yahoo domains?

There are a few settings we can play with, among others: * Number of concurrent connections from a single outbound IP * Number of messages per connection * Number of connections per minute * Number of messages per minute I'd put "unlimited" everywhere if I could, but most receiver

Re: [mailop] Resolving issues for several yahoo domains?

One of the interesting things I’ve learned while interacting with ESPs is that some of them will artificially restrict the number of messages per session, in lieu of opening more sessions. Some of them have told me the values are in the low single digits. I’ve kind of wondered the rationale for

Re: [mailop] Resolving issues for several yahoo domains?

Yes, everyone. Some, very few, emails are accepted. I believe their servers are overloaded. I suggest everyone to back off a bit, for instance by limiting the number of concurrent connections per outbound IP to ... 1. Until it gets better. Forcing our way through is not gonna work, or help. The
