What version of bbPress are you using?
Is any other mail sent from the server?
Can you use a plugin like Instant Password to work around it?

1. Create a directory on your server called my-plugins
– create it on the same level as bb-plugins
and bb-templates
.
2. Put the unzipped plugin files into that directory.
3. Access the bbPress admin and activate the plugin.
