We have been experiencing difficulties with MX records. In the case of a couple of nodes for which MX records have been installed if sendmail is not running on those nodes, the e-mail addressed to them is sent to the other node to which it should be sent but, instead of staying there or being forwarded to some third node, it is held in defered status on that node, addressed to the node to which it was originally addressed and not deliverable. In one case, if sendmail is running, then e-mail addressed to that node is sent on correctly to the other node to which the MX record points but if the addressee user's personal forwarding is set to the node which should be bypassed by the MX record, it is sent on there despite the MX record. The MX record thus seems to occasion correct forwarding to the node to which it points but to stop working after that, leaving mail to be either sent on to the node which is supposed to be bypassed or sit in mailq in deferred status. For other nodes for which we have installed MX records, they work correctly. We would like to hear any possible explanations. ======== Douglas Kline Smithsonian Astrophysical Observatory kline@cfa.harvard.edu 60 Garden Street, MS 58 Phone: 617 495-7157 Cambridge, MA 02138

The lowest preference MX is responsible for making "final" delivery. If (as it seems here) it should deliver the mail locally, the MX host's sendmail needs to be configured to treat mail for its MX clients as local mail. (Other cases might include UUCP queueing, FAXing, or carrier pigeon delivery.) In the case of IDA sendmail, you may want to declare either PSEUDONYMS or ALTERNATENAMES, or declare the use of the LOCAL mailer in mailertable. -- * Christopher Davis * <ckd@eff.org> * <ckd@kei.com> * [CKD1] * MIME * RIPEM *
