sendmail on RHESv4 only works for users on mydomain.com - the program cannot send or receive mail from Internet hosts. The maillog error reads:
sendmail[9447]: l1QLfsAV009447: <user@gmail.com>... Unrecognized host name gmail.com (the same error is repeated for yahoo etc addresses).
I'm working with a recently installed version of RHESv4, with the following packages installed:
sendmail-8.13.1-3.RHEL4.5
sendmail-cf-8.13.1-3.RHEL4.5
cyrus-sasl-2.1.19-5.EL4
cyrus-sasl-md5-2.1.19-5.EL4
cyrus-sasl-gssapi-2.1.19-5.EL4
cyrus-sasl-plain-2.1.19-5.EL4
cyrus-imapd-2.2.12-3.RHEL4.1
cyrus-imapd-utils-2.2.12-3.RHEL4.1
cyrus-sasl-ntlm-2.1.19-5.EL4
cyrus-sasl-sql-2.1.19-5.EL4
My DNS server appears to be working correctly, with the expected dig and nslookup responses, and a pass (with a couple of unavoidable warnings) at dnsreport.com.

so imaps is missing, can't start, presumably because of this:

So this goes back to my earlier posting, which I deleted because there were no answers.
I can verify cyrus users on localhost, sasldblistusers works, and the sendmail and imapd certs are set to mail.mydomain.com.
Are the version conflict errors blocking sendmail from authenticating mail.mydomain.com on the Internet?
