Hi,

I've set up some accounts for a client, which aren't receiving any emails with ~4MB+ attachments. My most recent test which failed was a 5.8MB JPG from myself to a test email I've set up. The email never showed up on the server/webmail and obviously it's not being received by any mail client setup with that test account because it's not on the server.

I've also sent a plain text email which showed up in under thirty seconds, and an email sent from this test email to itself with two 750KB PDF attachments which showed up several minutes later, and another email with one 750KB PDF which showed up several minutes later, and then I forwarded the same email with two 750KB attachments from myself to the test email, which also showed up several minutes later.

(All were sent from my email (which is a gmail email, and has no problem sending large attachments) to the test email, except for one as mentioned above.)

Is there some kind of setting that controls the maximum file size that can be sent?

Would greatly appreciate any help! Let me know if you need any more information.

Exim Configuration Advanced Editor:

message_size_limit
Default should be 50 MB

You may want to check the exim logs for any errors.

Hi,

Thanks for your reply. I've gone and checked and I'm unable to find where to locate the Exim Configuration Editor in CPanel. I've found this link (from the CPanel documentation) which states:

(Main >> Service Configuration >> Exim Configuration Editor)
I'm looking at the main page in CPanel, but I can't see any where I can navigate to Service Configuration or Exim Configuration, etc.

Could you tell me where it is? I'll also check the logs while I'm there. Thanks!

WHM >> Service Configuration >> Exim Configuration Editor

is the correct path. You will need to have root privileges to access this feature, it will not be available in a WHM reseller control panel.
