[TYPO3-english] Problem with powermail validation

[Michael Albers]

Dear list,

When i setup a check for e-mail validation in Powermail, i encounter problems.
The javascript detection works just fine, but when i select the e-mail
field as senders email address in the backend, i always get the
message 'incorrect e-mail'. I'm using Typo3 1.3 and Powermail 1.5.3.

I can't find a solution, does anyone know how to solve this?

Best regards,
Michael
