Still getting "message has lines too long for transport" errors

Someone was getting this email bounce back yesterday “Jan 5 2024” about “message has lines too long for transport” so I found the forum:

and added the 3 lines:

.ifdef IGNORE_SMTP_LINE_LENGTH_LIMIT
message_linelength_limit = 1G
.endif

in the “remote_smtp:” section of “/etc/exim4/exim4.conf.template” and I rebooted the server a few times yesterday.

But, I just had a different person complain of the same problem today (Jan 6 2024)

And I see this in my log file:

2024-01-06 12:59:05 1uOUsm-000x7F-32 ** [email protected] R=dnslookup T=remote_smtp: message has lines too long for transport

Any idea why it is still happending?

Thanks!

You must also add IGNORE_SMTP_LINE_LENGTH_LIMIT = 1 at the top of /etc/exim4/exim4.conf.template or the ifdef block will be ignored.

Example:

######################################################################
#                                                                    #
#          Exim configuration file for Hestia Control Panel          #
#                                                                    #
######################################################################

SPAMASSASSIN = yes
SPAM_SCORE = 50
SPAM_REJECT_SCORE = 100
#CLAMD = no
IGNORE_SMTP_LINE_LENGTH_LIMIT = 1

[...]

Remember to restart exim:

systemctl restart exim4
