Long story short is I need to get an SMTP server setup inside a client's network that I can send emails out of. This thing won't need to receive emails ever, and really only needs 1 email account customercare.
What can I do? Will I have to have the networking company open a port in the firewall? Is there one built into Microsoft Server 2003?
Long story: client paid networking company to move their website in house. Now I have to figure out how to email out from their website even though they don't have an SMTP server. At least until I install one.
Their email is hosted with Gmail right now (the client's domain through Google App for Your Domain). I changed my code to connect as one of their users "firstname.lastname@example.org" and send email. Worked great for about 12 hours.
All of a sudden none of the automated emails are going out now, and google is sending the emails back saying that it is a permanent failure and Message Rejected. The link they direct me to, http://mail.google.com/support/bin/answer.py?answer=69585 is telling me that our emails look like spam. They aren't. They are emails we send to out clients about the status of their applications. Seriously, they are NOT spam.
