Sorry about the flurry of questions today, I'm still getting my feet wet with postfix.
pflogsumm pointed out these three warnings about TLS: Mar 28 04:47:54 mail postfix/smtpd[22135]: warning: TLS library problem: 22135:error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:578: Mar 29 15:12:39 mail postfix/smtpd[35073]: warning: TLS library problem: 35073:error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown:s3_pkt.c:1102:SSL alert number 46: Mar 29 16:54:20 mail postfix/smtpd[35583]: warning: TLS library problem: 35583:error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:578: Could these be from my users trying to login with incorrect SSL/TLS/STARTLS settings? There are no warnings today and I got all my users' MUA settings squared away late yesterday. (I moved us to postfix on Friday night.) -Terry
