I have been having the same problem, did anyone ever respond to this post by chance, maybe on a different forum?

The addresses used are picked from a file and sometimes are not formatted correctly. Specifically, how is an address with an embedded blank after the '@', e.g 'xxxxxx@ doofus.com', handled. Is it logged someplace as being a bad address. It doesn't appear in the sent logs so I presume it is determined internally to be bad at some point. What I'd like to do is be able to capture these addresses when they happen for additional processing. Thanks.
