is rumored to have said:
The problem:
On the postfix-2.10.X mail server , the server does not deliver localy
the mail for the localy hosted recipient accounts but try to resend
the mail to the "mailHost" (taken from Ldap).
So postfix-2.10.x detect a loop and drop the message.
The message in aillog looks like: postfix/bounce: bounce_append_proto:
............. act=failed why=mail for my-server.mydomain.fr loops
back to myself
If you want to deliver mail to my-server.mydomain.fr recipients locally,
my-server.mydomain.fr MUST be in either mydestination ("local" domains
with system users,) virtual_alias_domains, or virtual_mailbox_domains.
See Postfix's ADDRESS_CLASS_README for more information.
What I tested:
a) I have removed the "transport_maps" parameter fom the "main.cf"
configuration file , and restart the postfix server:
* so the mail delivery for the local account works fine
b) I try with a custom 'tranport_maps" parameter like this:
* transport_map = hash:/etc/postfix/transport
with the "transport" file like this:
my-domain.fr :
.my-domain.fr :
* : another-mail-server.fr
then "postmap transport" to generate the .db file.
* result : the mail delivery for the local account works fine
That is surprising because the format is all wrong. Those freestanding
':' should make everything there useless. See the man page for
transport(5). A hash map has exactly 2 tokens per line, whitespace
delimited, with the second being of the format 'transport:nexthop' where
'transport' has an entry in master.cf.
