Hi there, I'm not on this list, so please make sure that replies go to [EMAIL PROTECTED] as well, thanks.
I'm not sure if this is an Exim issue, or an nscd issue. But I can't really find an answer. We have an Exim-setup with about twenty machines doing email for our customers. We do about 70 emails/second on a loadbalanced environment and after scanning for spam we deliver about 10 emails/second in people's mailboxes. The delivery is loadbalanced over three machines. (See the config attached to this email) All works well, except for an 'Unrouteable address', once in a while.

The users exists thanks to libnss-ldap, combined with nscd. As far as I can tell, the only thing that could cause these messages to bounce is 'check_local_user'. According to the Exim documentation, check_local_user does a getpwnam. Should I assume that, if Exim says 'Unrouteable address', the getpwnam-reply was 'User does not exist'? If so, the problem would lie in nscd, giving false replies. As far as I can see Exim should tempfail if it sees an LDAP error, and not 'Unrouteable address'. If anyone has a cluebat, please hit me with it. :) Thanks! -- Mark Schouten, Unix/NOC-engineer BIT BV | [EMAIL PROTECTED] | +31 318 648688 MS8714-RIPE | B1FD 8E60 A184 F89A 450D A128 049B 1B19 9AD6 17FF
