Problem CPANEL-39824 : message has lines too long for transport - Since January 21, 2022
-
65536 was the first iteration of the fix we created for this issue. There were still a few clients that were experiencing problems, so we raised the limit even further with a later release. 0 -
Is it possible to set the limit above 1,000,000 ? I am still having this issue for some client when they forward/reply too many times. 0 -
@awesomesites - no, there isn't a way to set that value any higher than 1,000,000. 0 -
Hello @cPRex and all other cpanel mates, I have the same issue, i have exim 100.001000 !!! and i still receive the h... " too long" at many, many customers. Is there any date to achive a fix to this ? I think is not serious by Cpanel dev team to take years to fix this. I know its not a game to program it, but come on ! you are the programmers, you have the source code .. I have many customer not happy here, all us are losing ... Thanks for any reply. 0 -
@AlbertoFX - have you already changed the default value? 0 -
@AlbertoFX are you using a mail relaying service like MailChannels? You will need to update the "TRANSPORTSTART" section to include "message_linelength_limit = 1000000" or whatever you want it to be. 0 -
@AlbertoFX - have you already changed the default value?
Yes, i did it ... but no success .. please, if you have any other solution let me know it. I am using to send mail smtp2go services, i dont know if this affect.0 -
Can you try the details mentioned by @DennisMidjord since you're using a smarthost? 0 -
Im using cPanel email hosted through Godaddy. I can not access the Exim config file or know where to find it. I have spoken to their support team multiple times and they can also not find it. Any guidance would be really appreciated. 0 -
@RubenGouws - they would need to access this through WHM >> Exim Configuration Manager. The value is called "Maximum line length for SMTP transports (Minimum: 1; Maximum: 1,000,000)" 0 -

I have spoken to a few of their support guys and they have no idea where to access WHM. Can you please send me a link that I can give them maybe?0 -
T @RubenGouws - if you have a shared account, I guarantee they know how to access WHM, they just don't want to make the change for some reason. The WHM URL is always
Thank you again for the replay. Its a pitty that this might be the case. I will call them again. I have tried to access it from my side but comes back with " This site can"t be reached" Hopefully they will help now.0 -
So @RubenGouws - if you have a shared account, I guarantee they know how to access WHM, they just don't want to make the change for some reason. The WHM URL is always
So I Spoke to godaddy again. Now they admit I do not access the WHM as I'm on a shared server with many other customers. I do understand, however, they refuse to make the change in the setting as they think I'm might impact other customers. So I'm screwed and can not use the panel at all.0 -
I agree, you would not have access to WHM. From my perspective, there really isn't an impact for end-users for this change, and raising it shouldn't be a problem (before some recent Exim changes there wasn't a limit in place at all) but unfortunately it is up to them how they handle their servers. 0 -
Ok I change the message linelength limit in Exim Configuration Manager -> BASIC Editor -> Maximum line length for SMTP transports to 65536, and as suggested I changed the TRANSPORTSTART section adding a "message_linelength_limit = 65536" because I'm using mailchannels, as suggested here: But when I run this command:exim -bP transport_list | while read list ; do echo "$list" ; exim -bP transport $list | grep line ; done I get this message: [QUOTE] mailchannels_smtp message_linelength_limit = 998 mailman_virtual_transport mailman_virtual_transport_nodns remote_smtp message_linelength_limit = 65536 dkim_remote_smtp message_linelength_limit = 65536 address_directory address_pipe virtual_address_pipe jailed_address_pipe jailed_virtual_address_pipe cagefs_address_pipe cagefs_virtual_address_pipe address_file boxtrapper_autowhitelist local_boxtrapper_delivery virtual_boxtrapper_userdelivery dovecot_delivery dovecot_virtual_delivery address_reply
What exactly do exim -bP transport_list | while read list ; do echo "$list" ; exim -bP transport $list | grep line ; done does? (it's a code I got from this thread). And where I can find that mailchannels_smtp message_linelength_limit = 998? So I can change it.0 -
@mapachio - I checked a test server, and I don't have the 998 limit on my machine. While you should not change the file directly, can you check your /etc/exim.conf file to see if the 998 value is present there? If so, it may have been configured in WHM >> Exim Configuration under the Advanced Editor tab. 0 -
Hello, I am running version 110.0.5 of cPanel and got this error message despite having the variable "Maximum line length for SMTP transports" set to "40960" I hope changing it to "500000" solves this issue 0 -
After the change to "500000", another message bounced so I am changing the value to the top limit 0 -
Let us know what happens! 0 -

I also use MailChannels, how can we change the configurationmailchannels_smtp message_linelength_limit = 998
? I have searched in every configuration file, but I couldn't find that setting.0
