[asterisk-users] Slow list

[Duncan Turnbull]

I thought initially it was a pretty poor generalization about postgrey and our capabilities until I realized that this was sent a
few weeks ago when this probably wasn't an as obvious issue. But it clearly is an issue now.

I have checked my mail servers for failures, implicitly greylisting is working as the mails are coming from digium constantly - just
a long time delayed, if postgrey was an issue there would still be retries and there have been none in over a week - as long as my
logs go back, any decent mail server should have retried in much less than a week.

Anyway - a discussion and investigation of issues is made pretty hard with 4 -10 day gaps in it. Since every other list works on
time (+- a few hours) its looking like Digium from my view.

I imagine someone will have sorted it before I see my own post, fingers crossed.

Cheers Duncan

What you can't see without looking at the mail server logs on both ends
is delivery attempts. Greylisting for example can totally hose you over
depending on the implementation. Greylisting without whitelisting is
irresponsible.  How many tries did the digium server make before the
message finally got through??? That's what we need to know. Only Digium
can say.

Before poking Digium too much, I would look at exactly what YOUR mail
servers are doing that may potentially be the real cause of the delays.
