Configure the IBM i SMTP Client to use SMTP Authentication without SSL/TLS

We try to configure the IBM i SMTP Client to use SMTP Authentication without SSL/TLS

We can send the email to a receipt that having the same domain as sender.

However, when sending to a receipt that with different domain, the receipt cannot get the email.
And the SMTP server reports that no email received from SMTP client


Use Case:

We can find a link that needs SSL as below
http://www-01.ibm.com/support/docview.wss?uid=nas8N1018618

Would you consider to let System i support SMTP Authentication without SSL fully (i.e. include sender and receipt can be in different domain name?

    With the following ptfs applied,
    R7.2 SI73279
    R7.3 SI71467
    R7.4 SI73266
    IBM i provided limited support to foward emails to exchange server with/without SSL.

    If I understood your use case correctly, IBM i SMTP client is required to foward all outside emails to the exchange server with "ONE" login id and password. SSL is an option. In this case, the following steps below could provide IBM i SMTP such capability:
    1. Add domain name of mail server
    CHGSMTPA FWDHUBSVR(domain-name-of-the-exchange-server)
    2. Add the Aunthentication infomation to IBM i Client
    ADDSMTPLE TYPE(*HOSTAUTH) HOSTNAME(domain-name-of-the-exchange-server) USERNAME(login-id-of-the-exchange-server) PASSWORD(password-of-login-id)
    With these configuration, IBM i smtp client sends all non-local emails to the exchange server and authenticate with exchange server the login id and password configured. This works for the case SSL required or SSL not used.
    Current IBM i only supports 2 authencation method: PLAIN and LOGIN. If exchange server requires other authentication methods, such as NTLM, kerberos, IBM i SMTP client would fail.

    If multiple receipts on different domains are specified in one email, the email will be split into several emails based on domain name and be forwarded to mail hub server. All receipts could receive the email.

    Does this meet your business requirements? If not, please provide more detailed usage for me to investigate.

    IBM i SMTP acted as email client to send out email through a Microsoft exchange server.
    The exchange server supports SMTP AUTH in using "ONE" login ID and Password for all email address in a company, with or without SSL connecting to that exchange server

    We are using the API "QTMMSENDMAIL" to send out the email (I believe you may try a simple way as by command SNDSMTPEMM)
    For detail, please refer to PMR 06783,999,738

    Yes, the company would like to have SMTP AUTH without SSL

    Could you describe more details about your use case ? Such as what role does IBM i SMTP play? Which type of SMTP server is used? What SMTP AUTH are supported by the SMTP server? It's better to have the email sending process to understand your use case clearly.

    When you say "use SMTP Authentication without SSL/TLS", do you mean the SMTP is safe enough to send the password over network ? If not, TLS is preferred to protect the SMTP username and password.
