Is there FC11 x86_64 as base OS?

 

[m0rpheu5]

it´s centos x86_64, i already find the problem, it was on /usr/lib64/sasl2/smtpd.conf, i needed to edited then and remove from the line mech_list: the option DIGEST-MD5, so in this line now i have only:

mech_list: CRAM-MD5 PLAIN LOGIN

but why this??

Thanks
