At my company we're doing almost the exact same thing. FOr this we use Postfix on RHEL5 with MySQL for domains, users and aliases. With about ~10k accounts everything works great except the forwarding vs SPF problem, ie:
1. someu...@hotmail.com sends a message to i...@yourcustomer.com 2. your server forwards this message to yourcusto...@hotmail.com 3. hotmail rejects the message because your server is not allowed send messages from someu...@hotmail.com I believe the solution to this would be SRS, but haven't found any such solution for Postfix yet :( http://www.openspf.org/SRS Martin On Fri, 15 May 2009 02:53:19 +0200, Scott Haneda <talkli...@newgeo.com> wrote: > A client of mine has a web service where a simple web page can be made > via a browser to crete an identity for them online.
