I’m using 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.
