Amazon SES questions

Please find my response below,

1. Does SES support sender list? If you're referring to managing a directory of email addresses to whom the SES can send an email, then yes it's supported. Please refer here

2. Lock access to source IP address? Amazon SES leveraged Shared IP pool and it could change even if you find the IP address. So locking it - check out Dedicated IP or BYOIP

3. Can SES support AD user authentication? Can you please provide more information on this? In general, no support for Active Directory (AD). Amazon Simple Email Service (Amazon SES) uses the Simple Mail Transfer Protocol (SMTP) to send email. Because SMTP does not provide any authentication by itself, spammers can send email messages that claim to originate from someone else, while hiding their true origin.

Most ISPs that forward email traffic take measures to evaluate whether email is legitimate. One such measure that ISPs take is to determine whether an email is authenticated. Authentication requires senders to verify that they are the owner of the account that they are sending from. In some cases, ISPs refuse to forward email that is not authenticated. To ensure optimal deliverability, we recommend that you authenticate your emails.

If you're talking about authorization with Amazon SES, please refer here.

This link describe two authentication mechanisms ISPs use, please have a read.

4. Supports both SMTP and SMTPS protocols Yes, it does support both protocols. TLS Wrapper is also knowns as SMTPS or the Handshake Protocol and it's one of the two mechanisms for establishing a TLS-encrypted connection. Please refer here for more information.

5. Able to bind to SES service on multiple TCP ports Can you please provide more information on this? I don't get your usecase or reason behind this request, but in general you configure on a single port based on the protocol you use. Check out this doc which talks about different ports leveraged by two supported protocol.

Hope this helps.
