IMAP Fetch behavior on not found messages

[Raphaël Ouazana]

|Hi, When adding the support of James on the integration testing of the 
gatling-imap project, we discovered some discrepancies between the 
behavior of James and Cyrus on IMAP fetch. When doing a fetch with some 
non existing messages Cyrus will do a best effort and return the 
existing messages whereas James will return a BAD response. And in case 
of a fetch on an empty mailbox Cyrus will return a NO response where 
James will return a BAD one. The discussion can be found here: 
https://github.com/linagora/gatling-imap/pull/3 Following our research, 
there is no clear indication of what should be done in the RFC. What do 
you think should be the behavior of James, should we keep its strict 
behavior or relax it as Cyrus ? Cheers, Rémi & Raphaël. |
