[Hampshire] Email return-to-sender - who has dropped what where?
Hello, I am starting to get mail return-to-sender failures sent back to a server for one addressee. The script wants to send the message to b...@hughes-energy.com (Names left of the '@' changed. I have left the domain name unsanitized) The failure msg looks like this: = Date: Tue, 3 Nov 2009 02:45:37 -0500 (EST) From: mailer-dae...@messagingengine.com (Mail Delivery System) Subject: Undelivered Mail Returned to Sender To: lal...@ws.qonnectis.com Auto-Submitted: auto-replied [-- Attachment #1: Notification --] [-- Type: text/plain, Encoding: 7bit, Size: 0.5K --] This is the mail system at host gateway1.messagingengine.com.

Looks to me like b...@hughes-energy.com is translated/resolved/forwarded (never quite sure of the terminology) to bo...@h-ems.com, but then whilst it is trying to resolve bo...@h-ems.com, gateway1.messagingengine.com. finds that data.h-ems.com.h-ems.com does not exist. I am not sure how/why bo...@fastmail.co.uk comes in to it. I'd have though the whole thing would have failed before it got as far as him. Can somebody indicate from this information, what sequence of processes going on? I'd actually find it quite useful to get more of an idea of what is happening.

However it looks like b...@hughes-energy.com is forwarding to bo...@h-ems.com and that mail to h-ems.com is broken because of the broken MX record.

Thank you Simon, that seems to confirm the suspicions I had. Strange,
because the recipient seems to think the destination address is fine
("from their end")! Maybe it works from within their internal network
but not from outside.

The trailing / on the paths is very important. rsync copies everything after the last / in each path. but, by 'keep them the same', did you mean that you're going to reuse the existing /home and /boot/ ? Or just that you want to ensure they're separate FSs again? in that case just mount the new disks under /dst/mount/home and /dst/mount/boot and rsync the entire / into /dst/mount Regards, Stuart -- Stuart Sears RHCA etc. "It's today!" said Piglet.
