Still getting “message has lines too long for transport” errors

[lhling]

@tccadam

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

Message has lines too long for transport

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!

I have handle by this topics:

IGNORE_SMTP_LINE_LENGTH_LIMIT = 1

remote_smtp:
  debug_print = "T: remote_smtp for $local_part@$domain"
  driver = smtp
.ifndef IGNORE_SMTP_LINE_LENGTH_LIMIT
  message_linelength_limit = 1G
.endif
.ifdef REMOTE_SMTP_HEADERS_REWRITE
  headers_rewrite = REMOTE_SMTP_HEADERS_REWRITE
.endif
.ifdef REMOTE_SMTP_RETURN_PATH
  return_path = REMOTE_SMTP_RETURN_PATH
.endif
.ifdef REMOTE_SMTP_HELO_DATA
  helo_data=REMOTE_SMTP_HELO_DATA
.endif
.ifdef DKIM_DOMAIN
dkim_domain = DKIM_DOMAIN
.endif
.ifdef DKIM_SELECTOR
dkim_selector = DKIM_SELECTOR
.endif
.ifdef DKIM_PRIVATE_KEY
dkim_private_key = DKIM_PRIVATE_KEY
.endif
.ifdef DKIM_CANON
dkim_canon = DKIM_CANON
.endif
.ifdef DKIM_STRICT
dkim_strict = DKIM_STRICT
.endif
.ifdef DKIM_SIGN_HEADERS
dkim_sign_headers = DKIM_SIGN_HEADERS
.endif

.ifdef REMOTE_SMTP_TRANSPORTS_HEADERS_REMOVE
  headers_remove = REMOTE_SMTP_TRANSPORTS_HEADERS_REMOVE
.endif

remote_smtp_smarthost:
  debug_print = "T: remote_smtp_smarthost for $local_part@$domain"
  driver = smtp
  multi_domain
.ifndef IGNORE_SMTP_LINE_LENGTH_LIMIT
  message_linelength_limit = 1G
.endif
  hosts_try_auth = <; ${if exists{CONFDIR/passwd.client} \
        {\
        ${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$host_address}}\
        }\
        {} \
      }

.ifdef REMOTE_SMTP_HEADERS_REWRITE
  headers_rewrite = REMOTE_SMTP_HEADERS_REWRITE
.endif

but it still has error:message has lines too long for transport

Any idea why it is still happening? Thanks

@lhling

.ifndef IGNORE_SMTP_LINE_LENGTH_LIMIT

It’s .ifdef but you used .ifndef, remove the n, save the file and restart exim.

@lhling

remote_smtp_smarthost

Also, Hestia doesn’t configure that transport so I suppose you added it manually.

Thank you so much!
