Cannot send email via sSMTP

[UlyssesZh]

I have a headless Arch Linux device, and I want it to send emails automatically through ProtonMail. I tried the following steps:

1. have a paid ProtonMail account
2. install and set up proton-bridge

   yay -S protonmail-bridge-nogui
   protonmail-bridge --cli # set up my account
   systemctl --user start bridge

3. install and set up ssmtp

   sudo pacman -S ssmtp
   sudo vim /etc/ssmtp/ssmtp.conf

   #
   # /etc/ssmtp.conf -- a config file for sSMTP sendmail.
   #
   # See the ssmtp.conf(5) man page for a more verbose explanation of the
   # available options.
   root=`MY_ROOT`
   mailhub=127.0.0.1:1025
   rewritedomain=pm.me
   hostname=pm.me
   UseTLS=yes
   TLS_CA_File=/etc/ssl/certs/ca-certificates.crt
   UseSTARTTLS=yes
   AuthUser=`MY_EMAIL`
   AuthPass=`MY_PASS`
   AuthMethod=LOGIN

4. send an email

   echo -e 'Subject: test\n\nTesting ssmtp' | sendmail -v `AN_EMAIL_ADDRESS`

Then I got the results:

[<-] 220 127.0.0.1 ESMTP Service Ready
[->] EHLO pm.me
[<-] 250 AUTH PLAIN LOGIN
[->] STARTTLS
[<-] 220 2.0.0 Ready to start TLS
sendmail: Cannot open 127.0.0.1:1025

ProtonMai Bridge has this error:

ERRO[Sep  3 20:47:26.949] TLS handshake error for 127.0.0.1:60910: local error: tls: bad record MAC  protocol=SMTP

It's very probable that this problem will just be solved if #245 is solved.

Were you able to get this fixed? I'm trying to do the exact same thing.

Were you able to get this fixed?

I gave up.

sorry to hear, but we don't have similar setup to test/help with the config.
