Hello, I just have this kind of logs for one remote domain.

2007-02-14 11:28:39 1HHHN8-0002Yi-Md CompletedThis is a _new_ mail sent from the internal server (192.168.100.12) from [EMAIL PROTECTED] to [EMAIL PROTECTED] using exim 4.66 as a mail relay between the internal server and the internet.
As we can see, a first attempt is made on the primary MX: SMTP1, it gets a 450 error for greylisting. Quite obviously exim retries to SMTP2 and also gets a 450 error. But exim never retries and interprets this as a permanent error.
One problem with SMTPX.lerelaisinternet.com is that they seem to never whitelist senders, they only let one message pass after the 5 minutes. So of course exim has never received from SMTP2 anything else than a 450 error code as succeeded deliveries always happen on the primary MX (SMTP1).
There have been former attempts to deliver mails from the same sender to the same recipient. And even other attempts to deliver mails to the remote relays SMTPX.lerelaisinternet.com for some other domains.
"delay_after_cutoff = false" is in the config file for remote_smtp so exim should try to deliver new mails. And indeed, it tries a delivery, but just once, not following the normal retry sequence. And as my relay never gets whitelisted, exim always receive two 450 error first on the two remote relays.
Is there a way to force exim to retry a really new queue sequence and not just try a single delivery even after cutoff time has been exceeded?
