Ok. Could a downstream server require that my server (that so acts as an SMTP client) communicate using a TLS connection? Could I neglect TLS configuration aspect if I don't intend to use TLS for exchange electronic mail? (I compiled Postfix with tLS support because I need to use authentication in conjuction wit SMTP). > Nothing you can do. The context below makes this rather clear... Still thanks, rocsca
