Re: Blacklisted by Hotmail

[Jeffrey Ramsay <jramsay () UTICA EDU>]

Tim,

There a couple of things you can do to remedy the situation.  I'm 
speaking from experience dealing with hotmail, yahoo and aol -- you can 
assign a second IP address to you MTA.  This new IP should be only used 
to transmit messages to these providers, but you will have to enable 
rate-limiting schemes depending how your users use the system in order 
to avoid being blacklisted again.

Overall, this is not a bad idea for transmitting all outgoing message -- 
here, some offices send messages to several hundred users at once and I 
have rate-limited them using burst distribution of 4-recipients per 
transmission attempt. AOL and Yahoo greylist your domain after 
5-recipients per connection attempt.
