We are getting this vulnerability on SUSE Linux Enterprise Server 11. This vulnerability is getting triggered on port 587 for postfix. I have checked several links but I am unable to get any relevant solution for it.

Has anybody faced an issue with this vulnerability? How do I remediate this?

Based on the links you've provided, this appears to be CVE-2011-0411. Given a CVE, you can browse at suse.com to see which packages will fix it. In this case, postfix >= 2.5.6-5.6.1 (patchname: slessp1-postfix) will correct the issue for SLES 11.
