Subject Re: How to use MailboxManager to insert a "fake" mail?
Date Thu, 14 Jun 2012 23:21:29 GMT
Hi, Eric,

Thanks for your hint. This bug finally turned out to be my mistake on
new line characters("\r\n", not "\n") used in mail body stream.

Now the server is switched to MySQL as backend mail storage. There is
one thing I can't find out myself with respect to this deployment
configuration.

There is only one collection opened by James after starting it up. I
am guessing James is using Apache's common DBCP as its database
connection pool(since I found this JAR in "lib" directory), but how do
I configure it? A grep within the James directory doen't yield useful
search results, and the manual on website also doesn't mention it.

Regards.
