Email Security Cloud + Office 365 +SMTP 22000 Emails + 6 domains

I need a solution

I have a customer for Email Security cloud, He have Office 365 , one exchange server onpremise and one server smtp from where he send 22000 emails dialily.

i had had thinking take the ip public from the two servers onpremise into Email Security Cloud like relay servers , both use the same ip public to send the email currently, them last step its a barrucada server, but i dont sure if the amount emails could be filtering by Email security cloud ,i found this post and this say that only there is restriction by connection dont by number emails .

Situation:

When sending bulk emails through the Email Security.Cloud product, the number of individual emails sent per SMTP connection is limited to 100.

(this is not the same as the number of recipients on a single email message)
 
Solution:

If more than 100 emails need to be sent at once, it needs to be broken into separate SMTP connections. This can be done in some mail programs, especially ones built around managing distribution lists, or by using an outside bulk mailer service.

its say i can send one email to with 22000 recipients but i dont cant send 22000 correo with 4 recipients each one. ¿rigth?

Too the customer have 3 domains currently ,but they will add 3 more , there is some number max to Domain checks?, and i have to ask the customer if all them use the same MX register for the inbound email ¿rigth ?

I need a solution

Good Morning,

Product: Symantec Message Gateway 10.6.3 (Virtual Edition)

¿It is possible use smtp authentication for outgoing mail forwarding to a smarthost?

In MTA > Administration > Configuration > SMTP > Outbound > Outbound Non-Local Mail Delivery > Non-local mail relay to the following hosts:

This option only allows you to add the IP of the remote host. (Not username and password)

In what place are the authentication parameters configured for forwarding mail to a autenticated smarthost?

Thank you

Outbound authentication failed with error %1 for Send connector %2. The authentication mechanism is %3. The target is %4.

Details
Product: Exchange
Event ID: 2017
Source: MSExchangeTransport
Version: 8.0
Symbolic Name: SmtpSendOutboundAuthenticationFailed
Message: Outbound authentication failed with error %1 for Send connector %2. The authentication mechanism is %3. The target is %4.
   
Explanation

This Error event indicates that outbound SMTP authentication on the specified Send connector failed with the specified destination smart host server. Typically, this error indicates an authentication problem on the Send connector, not on the target smart host server. This error is most likely caused when the Send connector is unable to obtain a Kerberos ticket for the target smart host server that is specified in the error message text.

When a Send connector is configured to route outbound messages to a smart host, the following authentication methods are available:

  • None

  • Basic authentication

  • Basic authentication over TLS

  • Exchange Server authentication

  • Externally Secured

In the Exchange Management Console, you set the authentication methods for outbound connections to a smart host on the Configure Smart Host Authentication Settings tab after you click Change on the Network tab of the Send connector properties page.

In the Exchange Management Shell, you set the authentication methods for outbound connections to a smart host by using the SmartHostAuthMechanism parameter on the Set-SendConnector cmdlet.

   
User Action

To resolve this error, verify that the Send connector and the destination smart host are configured to use a common authentication method with the correct credentials and required certificates.

How the Postmaster@domain address works

I’m very new to Exchange (in fact, an apprentice and studying it at the moment) and am wondering how the Postmaster@domain.com address works. An example:

A smarthost configured with one mailbox, Postmaster@serverfault.com, with an *@serverfault.com alias so, my understanding, all mail sent to *@serverfault.com is SMTP forwarded onto the postmaster@serverfault.com address.

But what happens now? Does Exchange have a master mailbox Postmaster, that receives all this mail and just dishes it out to the correct mailbox? Or is what I just wrote a pile of garbage!

So I’m a little confused. On the Smart Host – there is SMTP forwarding to forward all SMTP to IP Address x.x.x.x which is active for a mailbox on the smarthost called Postmaster@domain.co.uk with an alias of *@domain.co.uk? How is this working exactly?

Thanks!
