Hi, since I use TLS I'm getting the following waning when I send mail to somebody in the internet:| "warning: network_biopair_interop: error reading 5 bytes from the network: Connection reset by peer|" ... Mail seems to be delivered & sent as usual. I found a post about it: http://de.postfix.org/pipermail/postfix-users/2009-March/000891.html but it didn't help to involve: "smtpd_tls_ask_ccert=no" Did anybody face that issue before? I'm using self signed certs. Regards
