    I have trouble sending mail to the hotmail, outlook and other domains hosted by the same provider.
    The problem is that my isp's subnet is on the their block list so they refuse to receive mail from the servers are part of the blocked subnet (error:
    S3150). I dont have any problem with any other mail server...
    I'd like to route outbound mail to that domain over the other smtp server (ie. gmail) which uses STARTTLS and username and password to authenticate user. Other mails should be sent by my server.
    In the Advanced Email Routing I add new transport:
    Server: myserver FQDN
    Domain: hotmail.com
    Transport: smtp:smtp.gmail.com:587​
    In the Relay Recipients I add relay:
    Server: myserver FQDN
    Recipient address: (at)outlook.com​
    This setup works as expected but gmail refuse to accept email from my server because "Authentication Required".
    So I need somehow to send my username and password to the gmail smtp using STARTTLS (port 587)
    Can someone help me with it?
