Yes. I at least one other ESP has acknowledge to me that they are seeing this. I've also seen this change apparent in some gmail headers which show the time to delivery. It appears that Gmail started to make this change in February. We became aware of it in April and things only seem to be getting worse in May.
It looks like they have slowed the acceptance messages they will receive in a connection and they will refuse new connections from being opened. As this is pre-SMTP and we are using Momentum, we do not see a temporary failed attempt--we just see delays in sending out. This does not target any specific IP or IP group--this appears like a universal speed limit. This can result in significant delays--I'm not sure if these effects are known or considered at Gmail. - J On Thu, May 31, 2018 at 7:38 PM Jaren Angerbauer <jarenangerba...@gmail.com> wrote: > > On Wed, May 30, 2018 at 10:53 AM, Paul Witting <paul.witt...@bisglobal.com> > wrote: >> >> All, >> >> >> >> We’ve been getting complaints of slowness receiving mail and undelivered >> mail since last Saturday; all involve Gmail.
