There's a link on the webpage which explains the reason - apparently |
14 |
they would only accept messages with a From: address like |
15 |
user@××××××××××××××.org from my host. Anything which I've addressed |
16 |
from@×××××.com has to reach them via yahoo.com's servers. |

Sorry... I'm not sure that I understand. |
29 |
|
30 |
My Yahoo account allows me to use their servers for outgoing STMP. |
31 |
This is what I'm trying to configure Postfix to do. |

35 |
Yes. On Googling "mailertable" I am able to tell you that this |
36 |
appears to be exactly the same as /etc/postfix/transport |
37 |
|
38 |
So: |
39 |
$ cat /etc/postfix/transport |
40 |
lsv.uky.edu :smtp.mail.yahoo.co.uk |
41 |
tells my server that anything going to lsv.uky.edu should relay via |
42 |
my outgoing SMTP account at smtp.mail.yahoo.co.uk. This is a _little_ |
43 |
clumsy for my purposes, but adequate. |

Ah, looking up <http://www.mob.net/~ted/tools/mx.php3? |
69 |
domain=smtp.mail.yahoo.co.uk> I see what you mean. |
70 |
|
71 |
I don't see why postfix is looking up the MX record for it, either. :( |
72 |
|
73 |
My immediate reaction is: what if I host a fake MX record for |
74 |
smtp.mail.yahoo.co.uk on my internal DNS? I'm not sure of the |
75 |
implications of that. |

I think this would only satisfy mg1.uky.edu if you yourself relayed |
81 |
anything to its domain via Yahoo. And for that you would require an |
82 |
SMTP account with Yahoo. |

Stroller. |
