Since the 10.0 Release, FreeBSD ships its own Hypervisor: bhyve. Its possible to emulate BSD and Linux Guests, with Windows-support on the way.

FYI, 454 4.7.1 <someemail@example.com: Relay access denied; was the result of defer_unauth_destination. It's slightly different with reject_unauth_destination, with reject means permanent error with code 550 and defer means temporary error with code 450. But wait..., I don't have any parameter that use defer_unauth_destination. Where does the weird ...

Rationale for turning keep-alive on by default was given here: https://svnweb.freebsd.org/base?view=revision&revision=47752 Add handle to control global TCP keepalives and turn them on as default. Despite their name it doesn't keep TCP sessions alive, it kills them if the other end has gone AWOL. This happens a lot with clients which use ...

Dovecot allows you to configure a master user which can be used to access user mailboxes without knowing their passwords. The master user can be used with imapsync (as well as most other IMAP tools) to copy the messages between servers. From the dovecot configuration file on my server: By adding master=yes setting inside a passdb you make the passdb a ...

Two disks hardware raided into a raid1 will present a single disk to the OS, in this case mfid0 as you noticed. That single disk can't then be made into a raid1 on a software level. If you would've had four physical disks to begin with, it would be possible but quite silly. Chose either all hardware raid or all software raid. If you go for the hardware ...

When both mail servers use the same mail format (mbox, Maildir, MBX), the simplest solution is to just copy over the directory structures containing the mails, e.g. using scp. This also preserves the Message-IDs, as opposed to tools like doveadm copy. Another possibility is to use the IMAP-protocol itself for IMAP copying using tools like imapsync. But in ...

Unfortunately I do not have enough reputation to comment @Dan Pritts post. I have developed a board using Realtek RTL8211E phy chip and I can assure you, that it is able to operate on gigabit speed :) (actually 10/100/1000). The only problem with this phy chip would be if it had not been connected to the CPU using a gigabit interface (like RGMII for ...

How about the top's "load average" after some time of doing the speedtest? Does it ever reach 1? If it is not the CPU, maybe something is wrong with some lower layers? I suggest checking if ethtool or mii-tool show 1000FD in both cases (with and without router-in-the-middle). Maybe your router board forces some link settings and maybe you have a duplex ...

The cpu is not idling at all, one core 68.7% other 34.3% busy processing interrupts is not idle. The userspace is idle not the kernel. Not familiar with openbsd, can you set cpu affinity so that one core processes irq259 and the other irq260. Then see how busy each core is.

It could be something related to the network cards and the path between them and the kernel/cpu (including interrupt processing). You should look at verifying the various "offload" settings (sorry, I'm not familiar enough with FreeBSD to suggest the right tool). Also look for any other network-card driver-specific settings that can be tweaked, and ...
