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.
