Unknown sendmail log entry error

robeb · 05-07-2003, 02:53 PM

In my daily log checks I keep finding this entry:

sendmail[31151]: STARTTLS=client, relay=[127.0.0.1], version=TLSv1/SSLv3, verify=FAIL, cipher=DES-CBC3-SHA, bits=168/168

It appears about every 5 minutes. I am interested in finding out the cause of this error. I do not use sendmail, however, I have a Communigate Pro mail server that use a sendmail binary file. Can anyone tell me where else I might be able to find more information about this on my box (i.e. logs, cron jobs, etc) ?

hrm...is it five minutes on the money? i would check your cron jobs, do you have a proggie that checks for status information on sendmail, like netsaint (nagios)?

Yes, they appear every 5 minutes on the money. Can you elaborate more on the sendmail status checking?

My thinking on the status checking is usually these programs will open a socket on port 25 to your server and that will of course leave you some log entries....

Well a SSL/TLS connection is started and the certificate is invalid so the request failed.

Yeah...that makes sense. But, how would you go about determining why sendmail is trying to send an encypted message relayed through the localhost. That's what I can't figure out.

I guess it's not that big of deal...but stuff like that bugs me after I while if I don't know the cause of the error.
