While reading the Postfix SASL doc, (http://www.postfix.org/SASL_README.html#client_sasl), I puzzled over a few things.
- "The smtp_tls_security_level setting ensures that the connection to the remote smtp server will be encrypted, and smtp_sasl_tls_security_options removes the prohibition on plaintext passwords." Is that incorrect? Surely one would not want to send passwords in plaintext as this seems to state? - "With the smtp_sasl_password_maps parameter, we configure the Postfix SMTP client to send username and password information to the mail gateway server. As discussed in the next section, the Postfix SMTP client supports multiple ISP accounts. For this reason the username and password are stored in a table that contains one username/password combination for each mail gateway server." Figured I would ask before reading further. Is it not possible to authenticate to the same remote (receiver) with multiple sets of credentials? I ask as preliminary discussion with a potential provider seemed to indicate a "per user" authentication is required. Still waiting for clarification on that point. Thanks.
