We did change the retry rules.
This does not help at all.
Still delivery to Yahoo takes too much.
In my test case scenario with test.tld grey listing. Is this normal
behavior for Exim ?
Is this a bug ?
Should it be reported ?
Contacting Yahoo is not the issue here. We did that. They said they
will monitor it + some copy paste answers.
We comply with all their rules.
The issue is Exim retry policy.
Thanks again,
