Well yahoo's mx tend to do that a lot. i used to have a lot of  bounced
emails to yahoo until i implemented dkim, domainkeys and spf then all my
yahoo problems disappeared ,

I just want to know if you have implemented any of
these technologies dkim,domainkeys and spf, other wise you would have all
those problems

Hi All,

It seems that we're having some problems receiving emails from selected
Yahoo! Mail Accounts.  I noticed that there is a commonality between the
accounts that fails when sending an email to our domain (see email header
below)

Sorry, we were unable to deliver your message to the following address.

<xxxxxxxxxa () stluke com ph>:
Mail server for "stluke.com.ph" unreachable for too long


Um...it might be easier to get mail, if your host didn't close
the connection with a 5xx error.  :/

mpetach () hinotori:~> host -t mx stluke.com.ph
stluke.com.ph mail is handled by 20 qc.stluke.com.ph.
stluke.com.ph mail is handled by 20 mx1.stluke.com.ph.
stluke.com.ph mail is handled by 40 gc.stluke.com.ph.

I imagine when port 25 stops giving 5xx
failure message back, mail reception
might improve.   ^_^;
