So a non-Windows application is relaying email via a non-ICS windows SMTP relay server, which is so badly designed it's seen a source of spam? seems like you need a better Windows mail server, try SmarterMail which is what I use on my public server. For sending email with a single domain, it would be free. You may want to investigate it's concurrent connections first, but it includes numerous anti-spam methods so I expect it similarly avoids being seen as a spam source. It can be used for mailing lists. http://www.smartertools.com/ You may be able to create something similar with the ICS SmtpServer component and MailQueue, ideally we need a Pop3Server as well and that would make a complete mail server (with a lot of file processing in the middle). But that is a major project, particularly the spam checking side of it. It's on my very long term wish list, but not sure I'll ever manage it, meanwhile I make do with SmarterMail.
