Work around a line-length limit in poplib Work around a limitation in python2.7 implementation of poplib (for the pop3 protocol for fetching emails): It seems poplib applies a line-length limit not just to the lines involving the pop3 protocol but to any email content, too. This sometimes leads to tracebacks whenever an email exceeding this limit is encountered. We "fix" this by monkey-patching poplib with a larger line-limit. Thanks to Heiko Stegmann for discovering this.
