I am pretty sure we deliver on that machine with DKIM signed messages just fine. And people click on those mails too. No exceptional bounce rates.So not all messages are foobarred by default. Was it a percentage? David Hofstee
I just checked logs for the last couple of days, not all the messages are deferred, but only couple of them, mostly bigger messages.
But instead of getting any useful information from the recipient's MTA, the connection times out during DATA. As I can see from the packet dump, the recipient's side lowers MSS from 1460 (SYN) to 1380 (SYN/ACK), but doesn't ACK anything I try to send in DATA...
