How can i test to make sure a 2008 smtp engine on one of my servers is not blocking an email due to its attachment size. I can connect via telnet and run the usual commands to send a test mail and that works fine. I want to now run the same test but attach a file to see if there is a blockage.
Use case is:
emails being sent using this engine seem to block or stop at 3MB. I have checked all the usual settings in the smtp engine and made sure those are set to well above 3MB in fact they are set to 50MB plus but i want to run a manual test outside the app sending this email to remove the smtp engine as a possible blocker of the mail.
