I have an apparent greylisting issue with Shaw. I wonder if anyone else has noticed this. Shaw's mail server appears to only try either a few times or for a limited amount of time and then give up. I get lots of logs like the following (names have been changed to protect the guilty). After that, no further hits from that from address.
I had my greylisting time set to 29mins, but have now changed it to 15mins to try to get within the Shaw window.
Anyone else with a >16 min greylist delay might want to check their logs for similar behaviour, and/or take reports of missing emails more seriously. Please report back if you see similar behaviour.
Thanks!
