Hi all,

i am try to sent emails from a customer email (Not outlook but from inside his website) but nothing is coming in my inbox.

On whm > Mail Delivery Reports, email is not sending with error: "message has lines too long for transport". This appear and on others emails.

In exim configuration "Maximum line length for SMTP transports" value is 1000000, as i read inside here, but with no result. 

Any other idea?

  Hey there!  Can you let me know from "from inside his website" means?  Is this from a form on the site itself and not webmail?

  Hi again.

  It is a opencart 3.0.6 site, with an abandoned cart plugin. This plugin send an email if someone forget something in his cart.

  I can see email on "Mail delivery report" with error "message has lines too long for transport"

  

  We are seeing this problem and on other sites on the server, we just noticed it now, trying to get the plugin to work.

  Thanks for the additional details.  It would be best to contact the creator of that plugin to see if they have any more ideas, as I can't imagine any normal email message needing a line with more than 1 million characters.

  Thanks for your advice we will contact with plugin creator, but it is not the only account (who don't use outlook) with this error.
  but
  There are users with outlook, who even though they have increased "Automatically wrap text at characters" on outlook.

  Dear cPRex, the solution for my problem was this guide.

  On WHM > Exim Configuration Manager > Advanced Editor > Section: TRANSPORTSTART

  added those lines at the end of editor

  smtp: 
  driver = smtp 
  port = 587 
  hosts_require_auth = * 
  hosts_require_tls = *
  message_linelength_limit = 12048
