[tde-users] Kmail SMTP Issues

Hey all, I'm having to use Disroot's webmail service to send this since I am unable to send mail on Kmail for whatever reason for the past few days. I'm using SMTP and TLS but get the error "unrecognized transport protocol" whenever I try to send a message. Disroot's SMTP uses port 587 and STARTTLS, but I had been using TLS and Plain Text and the weird part is that this worked a few weeks ago but now it isn't. I'm able to get mail via IMAP but can't send anything. Does anyone else use Disroot and/or know how to fix this?
