I'm in no way an expert on this, and realize I might just get told that I'm inexperienced and should not even bother, but I want to know if it's possible to set up an email server on one of our computers while we're using Comcast's Business Internet. We have an email campaign that is generating too many return emails for me to use our Google Apps' SMTP. Would creating our own email server bypass emails-per-hour or -per-day limits imposed by Google Apps, or would we run into Comcasts' limitations too? This isn't spam related, we're not selling anything and we're emailing our users.
Any advice would be appreciated.
