hi, trying to figure out how to make RPCs via email i had to realize that the SOAPSMTPConnection class does not wait the specified number of millis before it polls the next request to the mail server. the constructor does not initiate the instance variable popPollDelay, so the line this.popPollDelay = popPollDelay; should be added to the constructor of SOAPSMTPConnection.java best greetings Mischa
