Are you sure that no firewall settings have been changed recently? Virus progams can sometimes block ports to stop mass worm mails. If so, add FileMaker Pro.exe to the program exception list.
Thank you for your post.
The advice from PhilModJunk is excellent (Thank you!). I know you are having trouble with the scripts, but let's try sending the email manually. That is, pull down the File menu and select "Send Mail...". Select SMTP Server, put in all the settings, and send a test email to yourself. Does this work? If not, then you will need to talk closely with your network admin to try and narrow this down further. If this does work, then go into one of your scripts that isn't working, and verify you have everything set up exactly as what you did manually. Then, test out the script again.
If you continue to run into difficulty, please let me know.
Actually, I try to stay away from Hard Alcohol :smileywink:
That advice was from the excellent Mr. Vodka, not me.
