Hi there,
Has anyone here got a Postfix server set up to relay through Yahoo's
SMTP service, please?
Normally when I send mail, postfix on the server under the stairs
connects directly to the addressee's mailserver (normal SMTP then) or
uses my ISP's mailserver as a relayhost. Until recently this
configuration has depended upon my mood - if I see a delivery failure
I muck about with things until I get it right, but from my desktop PC
I have recently started using the server-under-the-stairs more
frequently, so I am having to look more closely at its configuration
when things go wrong.
In this case I am getting a bounce message from a mailing-list server
that says:
<[EMAIL PROTECTED]>: host mg1.uky.edu[128.163.184.178] said: 554
5.7.1 Mail
from domain yahoo.co.uk not accepted from host
compaq.stroller.uk.eu.org
(213.152.39.90) - see http://www.uky.edu/email/ (in reply to
RCPT TO
command)
I want to sign up to this list using my @yahoo.co.uk address, you
see, so the logical thing to do is have postfix deliver everything
with a from address @yahoo.co.uk using yahoo's SMTP server as
relayhost. I understand that this is at least a little bit of a pain
<http://archives.neohapsis.com/archives/postfix/2004-08/0618.html> so
for me it's easier to send everything going to lsv.uky.edu via Yahoo.
I had expected this to be easy enough. Yahoo tells me that my server
settings are:
Outgoing Mail Server (SMTP): smtp.mail.yahoo.co.uk
So:
$ cat /etc/postfix/transport
lsv.uky.edu :smtp.mail.yahoo.co.uk
$ sudo cat /etc/postfix/sasl_passwd
smtp.mail.yahoo.co.uk my_yahoo_id:verysecret
$ sudo postmap hash:/etc/postfix/sasl_passwd
$ sudo postmap /etc/postfix/transport
$ sudo /etc/init.d/postfix restart
I then send the subscription mail again & look at the logs:

I'd be very grateful for any illumination on this one. I'm actually
using a somewhat dated release of Postfix but this software is mature
enough that I'm inclined to blame my own configuration rather than a
bug.
Thanks in advance for any suggestions,
Stroller.
