First of all, smppclient is great, so thanks so much for working on this project!
However, I was curious whether there was anyway to turn off the 60 second sleep/timeout whenever a source/destination address is invalid. It's fine that the message does not get sent, but a string of bad messages takes forever to be sent if the smppclient thread sleeps 60 seconds for each bad message.
If there's a variable I can set on initialization or anything, it'd be great to know! Thanks again!
