Hi, In the WildDuck email server (https://wildduck.email/ <https://wildduck.email/>) Haraka handles the MX part. I would say that Haraka is not exactly a server software but a framework. For example in the WildDuck setup it does not handle any queueing. Instead Haraka performs all of it's checks (eg gets spam score from Rspamd, verifies DKIM/SPF/DMARC etc) and then hands the message over to the WildDuck plugin that parses the message and stores it directly into database (WildDuck uses sharded MongoDB as the mail store). In our setup it processes about 1M incoming emails per day, peaks around 100k emails per hour, without any problems.
I have not used Haraka for outbound emails though. Mostly because the queueing mechanism that Haraka has does not play well with how WildDuck manages emails. Best regards, Andris Reinman > On 1.
