Random delays? One suggestion: Rich are you able to add several MX 
records for your domain, with the same address? e.g.

10 mail.aerifal.cx.
20 mail.aerifal.cx.
30 mail.aerifal.cx.
40 mail.aerifal.cx.
50 mail.aerifal.cx.

This may help to solve random lookup problems, as the lookup proceed 
with the other entries, when the first fails. This should add some 
retrial to the providers address lookup.

AFAIR, anywhere exists an official suggestion to have at least 5 MX 
records for each domain, may be all pointing to same address. I think 
those random failures are exactly the reason for this suggestion.

Harald
