Hi All,Our delivery success rate is very low for some domains, deliveries were failed due to the below reason.Messages queued (dynamic flow control).Messages queued (quotas met).I've gone thru the below document as well but still unsure what needs to be done to increase the success rate for those domains.https://experienceleague.adobe.com/docs/campaign-classic/using/sending-messages/deliverability-manag...Please find the screeshot of DX Rule for one of the domain. Is it causing the issue? Please help
Hello @ukender ,
the messages are queued because the email provider is not accepting this much volume. You will have to lower the volume defined in messages per hour for this domain.
You can read more about this here: Key points when managing deliverability in Adobe Campaign Classic
Also, If you are using the enhanced MTA then these MX rules won't work as these are managed by the MTA itself depending on your historic data.
More information on enhanced MTA is available here: Adobe Campaign Classic Enhanced MTA
there are several levels for the MX values.The faster is "boost" ( contact Adobe support about that)
I don't recommend using the enhanced MTA.You will lose the raw values of broadlog messages.
