Hi all,

We receive this error: "message has lines too long for transport" on some clients that they use outlook client.

We increased "Maximum line length for SMTP transports" on exim configuration from default to 50.000 and then to 1.000.000, but the problem is still there.

We use whm version 120.0.11 with almalinux 8.10.

Is there any other solution?

  Hey there!  If this is only happening to Outlook users, could you have those users try a different mail client?
