Multiple email points?

that page also has info about rocketchat

although, depends what kind of emails you need

due dates, etc only

or some other

https://github.com/wekan/wekan/issues/2830

about limiting webhook data

there is also some notification email related settings, that you see with command on server: wekan.help | less

These https://github.com/wekan/wekan/blob/master/docker-compose.yml#L256-L290

just for lowercase for snap commands

Well, then Wekan also has notification drawer like Trello https://github.com/wekan/wekan/issues/2471

Some contributor added it, but I have not yet figured out how it works :D LOL

Well, Wekan is full of features and fixes added by some 180 contributors, during about 5,5 years Wekan has been in development

of real time

combined about 13 years of coding work

Hmm...

or do you mean outgoing + incoming email per board?

like in Trello, that someone can send email and it appears to board?

Adding email settings to board settings

Like this, Feature request: Respond via e-mail, Trello style https://github.com/wekan/wekan/issues/2414

Hmm, maybe I'm going too much off-topic

I think you are just asking for adding server email settings per board

for SMTP server

Currently Wekan SMTP server settings are set with command line by server admin. This is the first time someone had asked to have multiple email servers. I'm thinking how useful this would be? Also, if any Wekan instance user that creates new board and that way becomes Board Admin, would be able to add any random SMTP server, in that case there would be a) possibility to send spam b) possibilitity to end up to some spam blacklist with misconfigured settings

Well, alternatively that multiple SMTP server setting could be at Admin Panel for each board name

Maybe this would be useful, if each board has one customer added to that board, and would receive emails for that customer speicific email server and email address
