Anybody from swisscom mail support reading this?
We are sending quite a few daily reminder-mails from a few of our web applications on behalf of our customers and regularly get temporarily blocked by the swisscom mail server with a simple "421 4.7.0 mail.swisscom.com closing connection". Is there a way to get whitelisted (at least for the recipient domains where we need to send these amount of mails)?
Cheers,
Mike
