🚀 go-pugleaf

Thanks to everybody for the numerous replies I got, but I didn't get any
solution, I think I didn't express myself correctly, so I'll ask my question
in a more general way :
Many nodes (generaly workstations) on my domain (not only my cluster) are often
unreachable, I'd like mails sent to those nodes, from the outside world, not to
be immediatly bounced to the sender but to be "buffered" into my MX node and
localy tried (for ie 48 hours) until the target node becomes reachable or
bounced to the sender if it doesn't becomes in operation after 48 hours.
The differents solutions I tried using MX RRs and define path command causes
mails looping from and to the MX node.
Does anybody has implemented a solution and can send me his MX RRs and DEF path
commands ?
Thanks in advance.
Herve
