Package: mailutils Version: 1:3.1.1-1 Severity: normal Tags: upstream According to http://cr.yp.to/proto/maildir.html letter R and S in message file name means that user has Replied and See(n) message. Unfortunately mailutils author does not follow this convention; R treates as Read , and for 'Answered' letter 'a' is used. This breaks compatibility with other maildir-aware software. I think that mailutils shold be more compatible with referenced spec.
I tried to discuss wiht package author but he insist for his approach.
