Question about line length limit in lmtp.

I have postfix + dovecot server. Mail for local users are saved by dovecot lmtp. Recently I got some messages from postfix:

--8<---------------cut here---------------start------------->8--- 4NQ07L4h4LztXXr: breaking line > 998 bytes with <CR><LF>SPAC --8<---------------cut here---------------end--------------->8---

This is because postfix has configured with default value lmtp_line_length_limit (990). I can turn off this limit (set to 0) but I am curious if dovecot lmtp will accept so lengthty lines? Does dovecot lmtp has any line limits?
