Re: Deferred - 452 4.1.1 Too much mail from this address E2210


 

Dellaina,

I've been trying to invite someone and from the very first attempt,
their email keeps getting returned with the following message:

Deferred - 452 4.1.1 Too much mail from this address E2210
As Bruce and Frances have said, this has cropped up before.

I have a slightly different take on it, I don't think that the service is necessarily running out of capacity, but rather that "this address" is referring to Groups.io as a sender. So a rate limit is being applied on the suspicion that Groups.io is sending spam.

If I'm right what has to happen is that the service needs to recognize Groups.io as a mail list service and remove the rate limiting (or apply a much higher one, appropriate to a mailing list service).

How to make that happen though is unknown. I know that Mark at Groups.io does his best to track down deliverability problems, contacting the receiving services as necessary. But maybe a word to the service's technical support from their own users would help.
