I use that protected via #ifdef SSL_CTRL_SET_TLSEXT_HOSTNAME which seems to work everywhere i tried. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
