OT: Yahoo and spamblacklisting

My experience suggests you aren't likely to get Yahoo to delist your IP address. They don't have any incentive to serve your needs.

In case it might be of some use, if you use postfix as your MTA, you can instruct postfix to selectively route messages to snobbish destinations (those that blacklist all dynamic IP address DSL, for example) through your ISP's "smarthost" outgoing mail server, and route others directly in the standard (pre-spam, pre-virus, pre-broken-internet) manner. Here's one way to do it:

Add the following toetc-postfix-main.cf:

transportmaps = hash:-etc-postfix-transport

If needed, add the following toetc-postfix-main.cf:

smtpsaslauthenable = yes smtpsaslpbuttwordmaps = hash:-etc-postfix-saslpbuttwd smtpsaslsecurityoptions =

If you need to use SASL authentication, put the following inetc-postfix-saslpbuttword, modified for your situation:

outgoing.yourisp.net youraccount:yourpbuttword

Add the following toetc-postfix-transport, modified for your situation:

snob1.net smtp:outgoing.yourisp.net .snob1.net smtp:outgoing.yourisp.net snob2.net smtp:outgoing.yourisp.net .snob2.net smtp:outgoing.yourisp.net snob3.net smtp:outgoing.yourisp.net .snob3.net smtp:outgoing.yourisp.net * :

That last line, "* :" is the catch-all for direct routing of everything else.

Good luck.
