Orbi
I have one Synology NAS DS918+ in local network (LAN side) and insntalled mail server. The SMTP 25 port forwarding has been configured on Orbi router and no problem on daily mail traffic. Try to configure router to send log to mail server on my NAS but occurred failure.
The failure message is "The specified port(s) are being used by other configuration. Please check your configuration of USB Readyshare, Remote Management, Port Forwarding, Port Triggering, UPnP Port Mapping table, RIP and Internet connection type. "
Try to disable the 25 port forwarding and send mail to gmail. The result is working. No idea why the notificaiton CAN NOT be sent to SMTP server via port forwarding.

What kind of "daily mail traffic"? You need port forwarding only if
you're running your own e-mail (SMTP) server, and you need it to accept
e-mail from the outside world. Is that really what you want? You don't
need port forwarding to handle e-mail between systems on your LAN, or to
communicate with external e-mail servers like Gmail.> Try to configure router to send log to mail server on my NAS but

than vague descriptions or interpretations.> The failure message is "The specified port(s) are being used by other

you're doing generally.It might help if you began again, and explained exactly what you want
to do, instead of asking how to implement some particular "solution" to
what you think the actual problem is.Thanks for reply. Let me have simple draw about the connection.
private IP <----------- | ------------> pubic IP
[ Synology NAS ] ----------------------------------------------- [ Netgear Orbi Router ] ---------------------------- [ Internet ]
Mail Server <------- port forward to private IP 25 port <------------ | connect pubic IP 25 port <----------- External mail server
smtp.user.idv
You're right. I configured MailPlus server on my NAS as URL you provided. Also configured port forwarding on Orbi Router to forward public IP 25 port to private IP 25 port. for example, the FQDN of Mail Server is smtp.user.idv and mailbox is admin@user.idv. The email exchange between external SMTP server and my Mail Server on NAS are working well. The mailbox admin@user.idv can get email from gmail or other mail box.
Loign to Orbi router web console. Select Advanced -> Seucrity -> E-mail. Check Turn E-mail Notification On. Input Primary E-mail box: admin@user.idv, YOUR outgoining mail server : smtp.user.idv, port is 25 and input authenticaion. Then, "Apply" the setting and got the following error message.
"The specified port(s) are being used by other configuration. Please check your configuration of USB Readyshare, Remote Management, Port Forwarding, Port Triggering, UPnP Port Mapping table, RIP and Internet connection type. "The emial notification settings CAN NOT be applied on Orbi Router.
Hopefully it's clear.
thanks.

Not really. I only know about setting up the email logs on the Orbi device itself and separately on my NAS devices. I am out of my depth when it comes to interactions between routers and NAS boxes.
My experience on Orbi and Netgear devices is that a lot depends on the smtp server and how it responds. Some smtp servers give no problems. For example, I use smtp-mail.outlook.com and gmail.com . (Anyone can set up a free account on those.) Some routers work with the Outlook server, while others prefer gmail. I have tried others lately.
Your subject says "Orbi". Your message is about a Synology NAS.
Which are you asking to send the logs?
If there is an Orbi in there somewhere, you might get better replies, and find other answers, over in the appropriate section:
