char* smfi_getsymval(
	SMFICTX *ctx,
	char *symname
Get the value of a sendmail macro.
Called When smfi_getsymval may be called from within any of the xxfi_* callbacks. Which macros are defined will depend on when it is called.
Effects None.
ctx The opaque context structure.
symname The name of a sendmail macro. Single letter macros can optionally be enclosed in braces ("{" and "}"), longer macro names must be enclosed in braces, just as in a file. See below for default macros.
RETURN VALUES smfi_getsymval returns the value of the given macro as a null-terminated string, or NULL if the macro is not defined.
NOTES By default, the following macros are valid in the given contexts:
Sent WithMacros
xxfi_connect daemon_name, if_name, if_addr, j, _
xxfi_helo tls_version, cipher, cipher_bits, cert_subject, cert_issuer
xxfi_envfrom i, auth_type, auth_authen, auth_ssf, auth_author, mail_mailer, mail_host, mail_addr
xxfi_envrcpt rcpt_mailer, rcpt_host, rcpt_addr

All macros stay in effect from the point they are received until the end of the connection for the first two sets, the end of the message for the third (xxfi_envfrom), and just for each recipient for the final set (xxfi_envrcpt).

The macro list can be changed using the confMILTER_MACROS_* options in The scopes of such macros will be determined by when they are set by sendmail. For descriptions of macros' values, please see the "Sendmail Installation and Operation Guide" provided with your sendmail distribution.
