For complete description of

a) the smtpd_sender_login_maps database queries

b) the order of queries

See: http://www.postfix.org/postconf.5.html#smtpd_sender_login_maps

You can test the queries with the postmap command.

postmap -q user(a)example.com databasetype:databasename
postmap -q user databasetype:databasename
postmap -q @example.com databasetype:databasename

You can also specify MULTIPLE maps:

/etc/postfix:main.cf
smtpd_sender_login_maps = mysql:whatever hash:/etc/postfix/default

/etc/postfix/default:
@example.com root

Don't forget to postmap the /etc/postfix/default file.

Great! That seemed to have worked really well! Thanks

Just a couple of questions, it is safe to give @mydomain.com an owner of
root in my hash file?
Also, what are your views on SPF? Just I ditch it, or go for it?

Cheers

Use a name that will never be used.

That depends entirely on your users. SPF assumes that mail won't
be forwarded, or that forwarders munge the sender address with SRS.

Ok so your solution (Adding another sender login map) worked on my
primary mx. Currently, my backup mx allows "relaying" to my primary mx
using a combination of transport maps and relay_domains. Any ideas on
how to get something similar working for my backup mx? It seems that the
sender_login_maps file is ignored for domains specified in relay_domains.

Thanks
