Self-service module can't send token via mail

Hi, everybody.

I want to use the self-service module. I have specified a gmail address for my user as destination for the token.

If I now click on “forgot password” in the module and select “email” as method, I immediately receive a message that the token is on its way.

However, no mail ever arrives on my gmail account and nothing happens in mail.log.

We have set a relay host for all outgoing mails. All other mails also leave our system via the postfix and this is also all in the log …

But the “self-service” module obviously can’t send any mail. In which log would the module note an error?

Have I missed anything?
