Issue with encoding of from and to fields

[boris-petrov]

Hi, I'm sending an email by doing something like:

def message = new MimeMessage(session)
// this intermediate `InternetAddress` is needed because of:
// https://stackoverflow.com/questions/31859901/java-mail-sender-address-gets-non-ascii-chars-removed/31865820#31865820
def address = new InternetAddress('"кирилица" <other@example.com>')
message.from = new InternetAddress(address.address, address.personal)
message.subject = 'some subject with кирилица'
message.content = ...
GreenMailUtil.sendMimeMessage(message)

(note the Cyrillic in the from address). In the debug logs I see:

10:10:43.065 [smtp:127.0.0.1:3025<-/127.0.0.1:33824] DEBUG c.i.greenmail.util.LineLoggingBuffer - C: From: =
?UTF-8?B?0LrQuNGA0LjQu9C40YbQsA==?= <other@example.com>\r\n

Which is what I would expect - i.e. the from header is correctly encoded and sent over the wire. A few lines down in the logs (where I've received the message):

10:10:43.155 [imap:127.0.0.1:3143<-/127.0.0.1:56364] DEBUG c.i.greenmail.util.LineLoggingBuffer - S: 8?Q?som
e_subject_?= =?UTF-8?Q?with_=D0=BA=D0=B8=D1=80=D0=B8=D0=BB=D0=B8=D1=86=D0=B0?=" (("????????" NIL "other" "exampl
e.com")) ([WRAP]

The first part is the subject which is correctly received. After that you see the from part which has question marks inside. After that, doing a message.getFrom()[0] on the received message returns these question marks. What is also strange is that message.getHeader("From")[0] returns the correct encoded value - not sure how that happens. But in any case, getFrom doesn't work which is not nice.

Am I doing something wrong or is this an issue in Greenmail? I spent a lot of time debugging this. 😄

Hi @boris-petrov ,

can you provide a test case snippet, e.g. based on EncodingTest.java?

Which GreenMail version are you using - latest 1.6.10?

[boris-petrov]

@marcelmay thanks for the answer! I've created a PR with a failing test: #479 The funny thing is that this fails only in the MessageCountListener - in greenMail.getReceivedMessages it is correct... no idea why.

Thx for the test case, that really helped.

`greenMail. getReceivedMessages' fetches the messages directly, without IMAP.
