MimeMessageHelper and from fields

We are using Spring 1.1.4 and WebSphere 5.1.

We are using MimeMessageHelper (as we need to use French text with accents and the like and SimpleMailMessage won't allow this) to send emails.If we set the from field to say "me@mycompany.fr" the resulting email has a from field of "me@mycompany.fr.domain.of.application.server. com" meaning the domain of the application server is tacked on the end of the from field.

Is this a Spring configuration issue?

Any help appreciated!

Cheers, Chris
