Re: [IMail Forum] OT: How to specify outgoing IP in MS SMTP

[Matt]

I have a few customers that need to send a moderate volume of E-mail (up to 1,000 at a time), and because of how they are managing their contacts, they are sending by way of Outlook or Office and need an appropriate relay server (i.e. not my hosted E-mail server).  Listservs are not appropriate for them because their lists are variable depending on what gets sent.  They aren't to the scale where a custom Web app makes sense for their either. I can get them setup to relay through MS SMTP without an issue, but I don't want to be mixing their traffic, or associating the reverse DNS name corresponding to the default IP of this box to their bulk E-mail.  I would much rather have them each use a single unique IP and self-named reverse DNS value.  That part isn't working with the way that MS SMTP is functioning now. If this doesn't work, I might just end up purchasing a cheap SmarterMail license to handle the setup, though I would prefer not to waste the money considering that I am only trying to enable my customers unique needs, and I'm not at all looking at getting into the bulk E-mail business.

I'm afraid that while these solutions would work for moving a single IP, it wouldn't work for multiple IP's. I can send E-mail just fine from the base IP of the box, but I would like to have separate outgoing IP's for each MS SMTP virtual server. They will all listen on separate IP's, but they all send from the same default IP. Just out of curiosity, why the need for outbound deliveries to be done on a different IP for each domain? On our gateways, all inbound and outbound deliveries are done on a single IP address.
