I've been trying to diagnose this problem for a while and just haven't made any progress. I would appreciate any suggestions you might have to offer. I'm attempting to get smtp to work on a fresh install of dspace. SMTP works on other applications in the website so I know that this is not a problem. When I attempt an smtp transaction through dspace i get an internal server error. I posted the log entry below. I've done a little research about the error and everything I read says its because the connection is lacking an ssl certificate, but I do not have ssl enabled for my internal smtp server. I've also posted an excerpt from my dspace.cfg file. Any suggestions would be greatly appreciated.
