That part I understand. I probably wasn't clear enough in my question, but what I'm asking is in two parts: 1. Does NeoMutt take the body of the message as...

It doesn't actually appear to be related to `text_flowed` being set, as it happens if it is unset as well (with `> ` being inserted rather than `>`). I thought...

Good question, how can I tell? I'm looking at the Udp section output of netstat -su on the application server. Edit: assuming it's the nebula buffers as there are no...

Interesting, thanks. Looking `ss -numpile` output I'm seeing the expected value wmem/rmem being allocated (double what's specified in the nebula config) and the sendq usage doesn't seem to come close...

Thanks very much for this explanation. I started changing sysctl settings before realizing that the nebula config had its own buffer size configuration. Looking through `ss -numpile` output, the odd...

> What is your `tun.mtu` setting? Any interesting logs from nebula? Nothing interesting in the nebula service logs, just handshakes. Nothing in syslog either that I can see. `tun.mtu` is...

Yes, only when using nebula. Works fine with no udp buffer errors otherwise. Both hosts have ipv6 enabled, but I did notice something in the logs that puzzled me: ```...

It was `0.0.0.0`, changed it to `[::]` but still getting send buffer errors.

Yup, restarted after making the config change, just a few handshake messages and four identical "Refusing to handshake with myself" error messages for the host in question.

"Refusing to handshake with myself" are all `level=error`. Error count still increasing, the amount is just dependent on traffic load (usually by between 30-80 at once). There are no further...
