NS 7.9 joind to a Win 2019 DC, will send out email but wont receive it. Port forwarding done and tested, mx records OK. Seems like an internal issue as a user cannot send an email to itself.
Long Story Andy, a company take over, this server has been sitting for a year waiting for a MS365 account to expire, now just want to switch email on to the NS7.9.
Using Roundcube webmail I can send an email externally to my email account and it arrives in seconds, but I cannot send an email to myself or any other user on the NethServer 7.9 from roundcube.
I use these guys at Elive for email filtering (but not in this instance) just using my own account to test the DuckDns is working, and you can see below it has connected sucessfully.
If you sent it to MichaelMiller@stephenmillerltd.com then notting came through. I am using roundcube on a local virtual PC (NS 7 & this VPC are in the same Proxmox 8)
This NS 7 was setup a year ago and only used Samba for file shares. First time to try as an email server. I think there is something fundamentally wrong as I cannot send internal emails from one user to another.
Both images are from the same productive and working NS8 VM, running on Debian on Proxmox. This system is using BtrFS as File System and AD as account provider.
My strong suspicion is that there is either no correctly configured account provider for mail (The Mail App), or it’s not set, therefore postfix’s internal user list (aliases) is more or less empty…
That would also explain the error message - and also why no incoming mail…
NS7 also needs an account provider correctly set!
(I do not at the moment have access to NS7 for screenshots!).
