As reported on Gitter by @viuha8 , the fetch mail account entries are ignored and the first one is duplicated.
A temporary work around is to create one <fetch> section per email account (leading to wasting resources as it launches several fetchmail deamons).
This buggy behaviour seems to be due to a bad, out of loop variable incrementation:
I believe the issue lies down in *server/protocols/fetchmail/src/main/java/org/apache/james/fetchmail/FetchMail.java* l. 425 -> 455
A `i` variable is used in order to iterate the entries but this `i` variable is never incremented (as it is incremented outside of the loop).
We need to write simple configuration tests, then fix this issue.
