I searched for this topic before posting it here, but with no luck, all the related solutions can't solve my problem. Therefore, I am here to seek your help. Thanks！
I am new to JavaMail and get stuck on a strange Decoding Exception while fetching some emails (only several in thousands). Have tried to set partialfetch to false, but doesn’t help. Below is the details:
Env: JavaMail 1.5.5, Jre1.8, Windows 10
Error: throws when call part.getContent():
- com.sun.mail.util.DecodingException: BASE64Decoder: Error in encoded stream: needed at least 2 valid base64 characters, but only got 0 before padding character (=), the 10 most recent characters were: "\n\r\n------="

I know the mail causing error is spam/ad, and can be ignored. But other email client can display the content so we need to support it as well. Could anyone please advise how to solve the problem? Really appreciate if anyone can shed me some light! Thanks in advance!
PS: below is the original email which causing error:
