I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm is installed for auth PLAIN It reports this from the EHLO so all looks good: 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 CRAM-MD5 LOGIN PLAIN 25...

The only thing I see is a message like sendmail[5452]: v9HIoBox005452: [xxx.xxx.xxx.xxx] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA with a close timestamp, but I'm reluctant to tie the two log entries together. Is there some log, or log setting that might enable me to tie the do_auth error to a specific IP address? I'm very reluctant to change mail servers to postfix or something like that....
