postgrey-1.35 delays user postings by hours or even days

[sbl]

I regularly notice significant delay in my postings to various osgeo-mailing lists of even more than 24 hours. That is of course quite inconvenient and inefficient for communication.

Checking the headers of a delayed mail, it seems that I am grey-listed at osgeo.

Is there a mechanism for whitelisting users?

Please find below an example from a header of a delayed email of mine:

(Hope I masked all possibly sensitive but no relevant information...)

No idea on how to do this, SAC can you give a hand?

Google gave me this (in case it helps):

I have added your outlook something server to

/etc/postgrey/whitelist_clients.local

followed by

service postgrey restart

Let's see if it helps.

Seems to be OK now (even though it was unpredictable when delay occurred)! Will re-open the ticket in case it gets necessary...

Thanks for the quick fix!
