New Revision: 1171854
URL: http://svn.apache.org/viewvc?rev=1171854&view=rev
Log:
Added generic ways to declare how a protocol replies to "too long lines" and to
"fatal errors". Not sure this is generic enough to correctly support
pop3/lmtp/imap, but this may be a first attempt at making it generic.
