My email processing system has suddenly started throwing error messages on line lengths recently: fetchmail: SMTP error: 550 maximum allowed line length is 998 octets, got 1047 fetchmail: mail from MAILER-DAEMON@<my email server> bounced to bounces+11930396-d424-darose=darose.net@sendgrid.meetup.com fetchmail: SMTP listener refused delivery The messages seem to be generated by exim. (I have fetchmail configured to pull my emails in from my ISP's mail drop, and deliver them to my exim daemon.) I've received a number of these in recent days. The first one occurred on Nov. 20 at about 9.30am (EST). I'm not sure what, if anything, has changed recently to start causing this. Anyone else run into this recently, or know what the issue might be? Thanks, DR
