exim based sendmail no data input line wrapping
Posted: 05 Nov 2021, 14:25
Hello,
There has been recent exim 4.95 changes made which.smtp transports rfc compliant:
unless attempted to be overriden:
Most email clients might be ok, but there's nothing really done on data input on Sendmail.pm to work around that.
Consequence is that we have mail delivery failures where sendmail is served by exim(which does no line folding/wrapping)
Of course it can be configured at this point to have those transports custom max line length, but there's no guarantee that this becoming more of a thing receiving party(exim based) would use similar customisation as well.
So maybe something can be done on on message parser at Sendmail.pm to wrap lines there?
Best Regards
There has been recent exim 4.95 changes made which.smtp transports rfc compliant:
Code: Select all
It based on RFC 2822 / RFC 5322 (Internet Message Format).
2.1.1. Line Length Limits
There are two limits that this specification places on the number of
characters in a line. Each line of characters MUST be no more than
998 characters, and SHOULD be no more than 78 characters, excluding
the CRLF.
Most email clients might be ok, but there's nothing really done on data input on Sendmail.pm to work around that.

Code: Select all
R=lookuphost_forward_router T=remote_smtp_forward_transport: message has lines too long for transport
