Title: Error when wending Mails: message has lines too long for transport
Post by: Iodok on June 15, 2026, 09:14:32 AM
Hi,

I am using roundcubemail v1.7.1.1 on Rocky.
Some clients get the mentioned failure when sending mails.
The error is:
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  [email protected]
    (generated from [email protected])
    message has lines too long for transport

Is there a configuration to configure automatic- linebreaks on webmail installations?

best regards

Iodok

Do you have an example of a message that causes the problem? May be its related to this issue https://github.com/roundcube/roundcubemail/issues/10198 ? There is a workaround mentioned in the ticket so may be give that a try.
