FVX538: e-mail logs port setting??

Hi -

I've been using an FVX538 for years now as a dual-wan router for my home.

I've used the email logs all that time, but Comcast has notified me that email will no longer be allowed on port 25.

Under the "Enable Email Logs" dialog in the settings, I don't see an option for setting an alternate port.

Am I out of luck on changing to the new port (465)??

thanks - Mark
