I setup a Citadel Mail Server on a RPI 3B+. I have DNS setup, port forwarding, and port open on firewall. When I enter through the webmail portal, I can send and receive mail just fine. The issue that I am having is with mail clients.
I can use IMAP and POP just fine to receive mail with my credentials just fine also.
Whenever I try to send mail using a client (tried a couple different ones), it fails on sending. Right now, I am not using SSL until I get it working on the basic port. The devices I am trying are local devices that do not pass a firewall. With sender authentication turned on, it always says invalid login even though the same login works for IMAP and POP. Turned off it says it requires a login.
For some reason it rejects logins to send mail even if they are a valid user on the system. Works 100% though with the same user on the webmail portal.
Any ideas on how to get this working?
Let me know if more info is required.

Not fully an answer, but since nobody is responding to this I will add the conclusion I got to when doing more research. Uninstall Citadel and find a tutorial for Postfix and Dovecot for RPI. I have it mostly working, but have a bit of work to do with StartTLS.

I am right there with you. I have an issue where I am attempting to attach an Outlook client to the server and it will validate IMAP just fine - but continues to blow errors on the SMTP portion on port 465. It's the same account, same password - but nothing I try - no conflicts with any ports etc seem to work.
I give up - especially since the documentation is all over the place - took a couple hours to figure out that
1 - You NEED to use letsencrypt to generate certs. Using self signed gives you unpredictable results. Oh and you need to put them in the right place - and not /etc/ssl/citadel. It goes into the /usr area.
2 - the locations of where it puts things are a haphazard jumble of google-fu to try and find - and half the documentation links are dead so....
I'm with you - Since I've learned what I need for DNS entries with my host such as proper A records, MX records and such, setting up signed auth certs with the lets encrypt cert bot etc, I could have used the several hours wasted on Citadel and setup a real stack with Postfix and Dovecot.
