You can however attach it to the SSL connection handle as "ex_data":
https://github.com/vdukhovni/postfix/blob/master/postfix/src/tls/tls_misc.c#L300-L304
https://github.com/vdukhovni/postfix/blob/master/postfix/src/tls/tls_server.c#L395-L406
https://github.com/vdukhovni/postfix/blob/master/postfix/src/tls/tls_server.c#L812-L817
and retrieve it from the SSL handle as needed:
https://github.com/vdukhovni/postfix/blob/master/postfix/src/tls/tls_server.c#L265
