-For outgoing mail to work, you might have to change the SMTP
-configuration in `protonmail-bridge` and set security to SSL instead of

+The bridge's default configuration of STARTTLS instead of SSL should

 [Protonmail]
-source   = imap+insecure://youraccount%40protonmail.com:yourprotonmailbridgepassword@127.0.0.1:1143
-outgoing = smtps+plain://youraccount%40protonmail.com:yourprotonmailbridgepassword@127.0.0.1:1025
-default  = INBOX
-from     = Your Name <youraccount@protonmail.com>
-copy-to  = Sent
+source        = imap://youraccount%40protonmail.com:yourprotonmailbridgepassword@127.0.0.1:1143

+from          = Your Name <youraccount@protonmail.com>
+copy-to       = Sent
+#smtp-starttls = yes # uncomment if using aerc <= 0.14
 ```
 
 The first time you run aerc with this configuration you can expect a
