Dear All,
I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. 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
I usually see that message when the SSL/TLS handshake failed in some way. Can you get a good connection to sendmail using openssl?
# openssh s_client -connect your.mail.host:25 -starttls smtp
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 250-DELIVERBY 250 HELP
Hmm. It'd be helpful to know your authentication chain:
1. The contents of /usr/lib/sasl2/Sendmail.conf
2. The contents of $MECH in /etc/sysconfig/saslauthd
Also, is saslauthd running?
