It seems like Postgrey needs to be restarted every so often. I start seeing spam get through, restart Postgrey, then it's fine for a few days. Repeat. Anyone else notice this?

| Can't say I've had it fail like that. It's not going to be perfect though, some spam works by exploiting mail forms in insecure web apps (that are backed by a standards-compliant retrying MTA) |

postgrey is a service that does a pretty simple thing. It simply pushes mail 300 seconds. smtp wait 300.
Do you have any indication (logs) postgrey decided not to do that?
I can assure you, some spammers can wait 300 seconds. postgrey is not fullproof. |

Not noticed that behaviour either; your're not getting log-entries from postgrey when that happens? ie.: | Quote: | Aug 08 12:21:29 mail.vlh.dk postgrey: cleaning up old logs...

Actually, it seems to be okay. Definitely a lot less spam now. Thanks, guys.
