Yes. There is a problem with exims retry mechanism if a remote system is greylisting based on recipient address, sender address and sender IP. As exim gets a temporary error for "RCPT TO", it thinks the mailbox is currently not available. Exim can't know that another e-mail in the queue with a different sender address could actually get through to the recipient. With a moronic greylisting setup (no auto-whitelisting) on the remote side and a lot of emails this really is a problem. One may choose at which side the problem is, though. lg, daniel -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
