Yes, I do control the server. This is a simple setup, no spamfilter or such things. And yes, besides the fact that in one case the sasl user is logged there aren’t any other differences.

Is this consistent across many servers? Does the delay scale based on

I only tested with one server, but the results are quite linear.
50 mails = x seconds, 100 mails = 2x seconds, 500 mails = 10x seconds.

If Wietse had said that postfix would do a sasl lookup for every mail (even if login and password is sent only once), then I would understand.

But I won’t debug the problem any further. It doesn’t seem to be that obvious so it isn’t really worth it.

Many greetings,
