IMAP Server - Messages are appended with wrong INTERNALDATE #211

Open Frolx opened 7 years ago

Frolx commented 7 years ago

Hello guys, I have an issue with GreenMail - IMAP server.

The messages that are appended to the GreenMail IMAP server using JavaMail Library, are stored with wrong INTERNALDATE.

The weird thing is that the issues occur between 12:00 PM - 1:00 PM.

Both the application in which GreenMail ran, and the client that appends the messages to the IMAP store, are in BST timezone. (I checked on UTC too)

I debugged the append operation until the messages are converted to bytes to be sent through IMAP protocol, the date / time is right but on IMAP server, the messages have incorrect INTERNALDATE.

e.g. If a message is appended at 12:33 PM, the INTERNALDATE of the message in the IMAP server will be: * 1 FETCH (INTERNALDATE "18-Jul-2017 00:33:30 +0100")

if a messages id appended at 13:21 the result will be : * 1 FETCH (INTERNALDATE "18-Jul-2017 13:31:55 +0100")

Maybe some of you had the same issue, thanks!

Hi @Frolx. Thanks for submitting the issue. I haven't seen this issue occur but then again I generally do not assert on specific times (just dates) for incoming emails.

Just to clarify - are you saying this issue occurs when a client sends in an email using BST OR UTC timezones?

Frolx commented 7 years ago

Do not send, just append using IMAP protocol. I tested on UTC and BST, in both cases result is the same.
