Hmm. IDEAS should not have mail. Make sure SPF records are there
Good thinking! For that I need the ip address for the new machine.
for all aliases.
It has to be done on a domain-by-domain basis. I will do it for the authors.repec.org domain. Our SPF is very strict. krichel@trabbi:~$ dig -t txt authors.repec.org | grep ^authors authors.repec.org. 3583 IN TXT "v=spf1 ip4:128.252.177.195 ip4:137.99.31.70 ip4:89.151.115.234 -all" For the case that somebody makes smtp callback, make sure the machine can receive mail to the sending address.
