Hi, Particulars: Red Hat Enterprise Linux Client release 5.6 (Tikanga) This last Thu morning (05.05.2011) my RHEL5 suddenly stopped accepting e-mails from other than itself. I don't know if the following is related, but the following updates were done around the time of the problem starting: ------------------------------ Delimiter BEGIN -------------------------------- May 05 08:28:43 Updated: xmlsec1-1.2.9-8.1.2.x86_64 May 05 08:28:44 Updated: 1:autofs-5.0.1-0.rc2.143.el5_6.2.x86_64 May 05 08:28:45 Updated: xmlsec1-1.2.9-8.1.2.i386 May 05 08:28:46 Updated: xmlsec1-devel-1.2.9-8.1.2.i386 May 05 08:28:46 Updated: xmlsec1-devel-1.2.9-8.1.2.x86_64 ------------------------------- Delimiter END --------------------------------- I have since downgraded those packages, but it hasn't helped. My IT department has checked various things and they say everything looks okay--but there is no explanation for why my system won't accept e-mail. I can watch the network traffic via tcpdump and send myself an e-mail from our exchange server and I see my system and the exchange server exchanging packets; but my system apparently is not accepting the e-mail. And exchange will eventually send a "Delivery Delayed" message. If I can't get this resolved I will be forced to use Outlook :( Any assistance would be *greatly* appreciated.
