Description Rolf Eike Beer 2022-07-23 18:24:58 UTC 
I want to reply to a mail which has many recipients and CC list entries. The reply get's rejected from my SMTP server as the SMTP body that is generated contains too long lines. When I look at the mail in the outbox I can confirm this: the To: and CC: lines are no wrapped, instead all entries are put in a very long line.

The hard limit for SMTP body lines is IIRC 1000 chars including the CRLF.
