Re: [qmailtoaster] mailserver on AWS

[Jeff Koch]

Also, we're evaluating Google Cloud Platform - seems a bit cheaper than 
AWS. GCP just plainly states that outgoing port 25 is blocked period. 
I'm not aware of any forms or options where you can request the block be 
lifted.  Ports 465 and 587 are open so website contact forms and 
transaction notifications could use smtp auth to get emails out if you 
have an email account outside of the platform.

Actually, what you do is set this up on the remote server... You create the SSH 
tunnel where the remote server [with port 25 open to the world], connected via 
SSH Tunnel to the remote server [and what port on the remote server you want 
the tunnel to connect to]... Usually, I use key pairs so I can restart the
