@mcktr requested the ability to send notifications via eMail from our Icinga 2 Docker image. There’s one problem: the container runs only Icinga 2, so even if one wouldn’t use a public MTA, but a local one, it would be an extra container – and over the network anyway.
As I’m not very familiar with server MUAs, so I need your help: What program you’d expect behind
- Non-127.0.0.0/8 MTA can be specified easily, preferably via a mounted
.PROGRAMNAMErcor env vars (may be specified at Docker level as Icinga 2 passes its own env to subprocesses)
- These ones have to still work
