Having the same problem after upgrading Form Tools and the Swift Mail module.
In the Swift Mailer config set up, I can send test mails to myself successfully. But with my form, I get this error - never goes to my confirmation page and never sends an email. Unable to send test emails from the form edit area - just from withing the Swift Mailer configuration panel.
Desperate for immediate help.
=========
Update:
Had to turn Swift Mailer off and the default php mailer was working - but after a null registration went through, even that stopped working.
Desperate for help.
Lasted Form Tool Upgrades installed.
Windows 2003 Server Enterprise
MySQL Version 4.1.22
PHP Version 4.4.7
