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.
mpetach@hinotori:~> nslookup qc.stluke.com.ph.

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