Messaging Gateway

Hi there.

We are testing the SMG for a month before deciding to whether to buy, but we ran into a problem:

We run a Exchange 2010 mail server on premisses, and installed the Virtual Appliance for the SMG 10.6.3-2 as our mail frontend, so all mailflow passes through it.

Single mail is going fine, but messages for bigger groups (20+ people) are being held on the Exchange Queue, with the error 421 4.4.2 Connection dropped due to ConnectionReset.

On the SMG side, im getting many:

- 4.7.1<external mail here>: Recipient address rejected: MX-PNM-02 - Too many messages, try again later.
- 421 4.3.2 The maximum number of concurrent connections has exceeded a limit, closing transmission channel

Is this on the SMG side or exchange side?

Hi

Please review the SMTP advanced outbound settings, I don't think that 20 to 50 recipients triggered that policy.

Maximum number of recipients per message

Indicates the maximum number of recipients permitted to receive a message. The default is 1,024 recipients.

Maximum number of connections from a single IP address

Sets the maximum number of simultaneous outbound connections that can be made from a single IP address. The default is 20 connections.

Best Regards

Ty, I will try it and post the results!

Please let us know if it worked or mark the issue as solved.

Thanks
