Module ngx_mail_smtp_module
Directives
Syntax: | smtp_auth |
---|---|
Default: | smtp_auth login plain; |
Context: | mail , server |
Sets permitted methods of SASL authentication for SMTP clients. Supported methods are:
login
- AUTH LOGIN
plain
- AUTH PLAIN
cram-md5
- AUTH CRAM-MD5. In order for this method to work, the password must be stored unencrypted.
external
- AUTH EXTERNAL (1.11.6).
none
- Authentication is not required.
Syntax: | smtp_capabilities |
---|---|
Default: | — |
Context: | mail , server |
Sets the SMTP protocol extensions list that is passed to the client in response to the EHLO
command. The authentication methods specified in the smtp_auth directive and STARTTLS are automatically added to this list depending on the starttls directive value.
It makes sense to specify the extensions supported by the MTA to which the clients are proxied (if these extensions are related to commands used after the authentication, when nginx transparently proxies the client connection to the backend).
The current list of standardized extensions is published at www.iana.org.
