verification received expires before i receive it.

When wanting to add an system to sync my settings, the send verification code received is delayed in transit and expired before i get it. That is due to greylisting on the emailserver. received email properties : X-Greylist: delayed 1196 seconds by postgrey Trying to add an 2nd email (corporate) email address to circumvent this problem... I have to use enter another verification code that expires in 5 minutes. and you guessed it, that is send to the first emailaddress. aha... how to cirumvent this verification code expiration ?
