Sending email from Emacs, authinfo error: Unexpected ‘machine’ token at line 2

Question

I am managing multiple email accounts with mu4e. Everything works fine expect sending emails: I am getting the following error

auth-source-netrc-parse-entries: auth-source-netrc-parse-entries: Unexpected ‘machine’ token at line 2

My authinfo file looks like this:

machine <...> login <...> port <...> password <...>
machine <...> login <...> port <...> password <...>

smtpmail-smtp-server, smtpmail-smtp-service and smtpmail-smtp-user are all defined in my mu4e configuration.

Answer 1

To solve this problem temporarily, I created 2 files: authinfo.gpg and authinfo2.gpg for each email address and added the following line in the configuration:

(smtpmail-auth-credentials . (expand-file-name "/path/to/corresponding/authinfo.gpg"))
