A small lightweight self hosted Transaction Email solution. owned by Krystal
it can be deployed with docker, has ip rotation built-in as well as tracking functionalities for emails send.
A few scenarios worth considering
Since its a mail server, it probably makes use of some ports already used by nethserver-mail.
What if mail module has not been installed, can this be installed and make use of the same ports without an issue.
Can it be installed to run alongside netherver mail?
@mrmarkuz mentioned that for used ports, a different network thats not aqua can be used, or alternatively another port on the aqua network.
can it run alongside Nethserver mail with no real repercussions.
For me, since i have multiple nethserver deployments spread across the internet, that do not use or have the need for Nethserver mail to be installed, i have always wanted a way to utilize those servers for delivering emails, while rotating the delivery servers based on the emails being sent hourly.
As we all know, if a single ip sends way too many emails, it becomes backlisted.
The software can solve that through ip rotation, but then again, the idle nethservers can also be utilized.
@stephdl a while back you presented us with an email list software, here is a transactional email server to go with it.
