sendmail? I had a problem with sendmail when I added ssl and auth support. I added a certificate for the server, but I didn't define one for the client. Whenever the outbound connection hit another server capable of ssl, it attempted to authenticate and establish an encrypted client connection. Without a client certificate it always failed. The "Deferred: Connection reset..." was the only clue in the log files. I tried to figure out how to get it to fall back to an unencrypted connection; but apparently sendmail doesn't like to do that. I resolved it by defining the server certificate as the client certificate too. Make sure you have a valid entry for: define(`confCLIENT_CERT', `/etc/mail/tls/sendmail.pem')dnl # path to server certificate define(`confCLIENT_KEY', `/etc/mail/tls/sendmail.pem')dnl # make sure it's unencrypted in your sendmail.mc and regenerate your sendmail.conf.
