Sendmail failed to extract CN
 
Hi,
I've just updated my Centos distro on one of my paired machines from
2.6.18-164.15.1.el5PAE #1 SMP to
2.6.18-194.3.1.el5PAE #1 SMP
My Sendmail version on both is 8.13.8/

Since updating I have seen the following messages in the logwatch reports (I have commented out hosts for privacy reasons)


--------------------- sendmail Begin ------------------------
**Unmatched Entries**
STARTTLS=client, relay=mail13.XXXXX.com., field=cn_issuer, status=failed to extract CN: 5 Time(s)
STARTTLS=client, relay=mail.YYYYYYY.ie., field=cn_issuer, status=failed to extract CN: 4 Time(s)
STARTTLS=client, relay=mail15.XXXXXX.com., field=cn_issuer, status=failed to extract CN: 3 Time(s)
STARTTLS=client, relay=mx.poczta.ZZZZZ.pl., field=cn_issuer, status=failed to extract CN: 1 Time(s)
STARTTLS=client, relay=mail03.XXXXXX.com., field=cn_issuer, status=failed to extract CN: 1 Time(s)

STARTTLS=client, relay=mail.WWWWWWWW.com., field=cn_issuer, status=failed to extract CN: 1 Time(s)
---------------------- sendmail End -------------------------
(Note these rarely occur on the non-updated server.)

Are these errors or warnings?
What can I do to address the issue?
Regards,
Tony

Thanks, but I don't understand, the machine is fully updated according to yum. You mean re-install Sendmail? Why?

Anyone got advice? Its very quiet on this forum...

Hi YouNix,

We have exactly the same problem with Sendmail and CentOS 5.5

Does anyone have a solution for this problem?

No we never came up with a reason or a solution. However, we are not getting complaints from our customers about missing mail so I think its more of a warning. However from the point of administration I'd rather not see these 'warnings' and keep a clean logfile. Any joy from your end?
