We are using an in-house system based around Delphi to send email via SMTP. Everything appears to be fine but we are getting numerous reports of emails not getting through. I have checked on line to see if we are blacklisted but we don't appear to be listed.
My question(s) are:
Are there any steps I can take to verify email is getting through.
Is there such a service where we can hire an SMTP server as we are currently ISP bound. We have tried using our hosting provider but we need the ability to send email from multiple accounts using the same SMTP login.
Any help greatly appreciated
Thanks in advance,
