Extremely long line
Hello everyone, I’m using https://github.com/karastojko/mailio <https://github.com/karastojko/mailio> to get messages from dovecot-2.3.7.2 (3c910f64b) and 1 of the messages which is 2.5 mbytes in size and has an image attached, has a half megabyte of <80> (0x80) characters at the end. And that is with default encoding of 7 bit (meaning there is no part headers at the end), right after the message those characters. I got a feeling that max length was 998 characters. On other hand, looks like dovecot is replacing NULL chars with 0x80.
Is that is correct behavior, should I expect that half meg of bytes in 1 line? Is it a known issue? Thank you. Dmitriy

So post your code that you're using to get the message from dovecot. I assume you're using IMAP?

Do you have a test case message that works? What version of dovecot is the server running?

It sounds more like a problem with the tool encoding the mail message. How did you create the message that you are trying to download?
Start with simple test cases.
- create a plain ASCII message and send it to dovecot.
- download the message and compare the message bodies.
Repeat steps 1 and 2 with more complex messages, such as messages with long long lines, etc.
But you really need to give us more details on how these messages are created, and how you're trying to read them.
What happens if you look at the message with another mail client? Does it fail? Can the message be read?
