$ postconf -d |grep 998
lmtp_line_length_limit = 998
smtp_line_length_limit = 998
Changing this does not solve any problem, because MTAs are expected
to do this.
RFC 5321:
4.5.3.1.6. Text Line
The maximum total length of a text line including the <CRLF> is 1000
octets (not counting the leading dot duplicated for transparency).
This number may be increased by the use of SMTP Service Extensions.
