Can receive emails, but not send?

It's usually the other way around. :confused: It was working fine until maybe 10 minutes ago. Only RoundCube works, but not local Outlook or Thunderbird. What am I missing here?

  Hello :) Do you receive any specific error message? Are you sure there are no new firewall or ISP restrictions on sending that's causing this issue (e.g. can you telnet to port 25 from your workstation)? Thank you.

  No. But it's been slower since Monday night, but it is working now. I almost wonder if Outlook was merely timing out. That's my guess now, seeing the slowness. The loads look fine. Nothing has changed on the server.

  You may want to review the disk I/O if it happens again to see if that's the culprit for the slowness. This thread may help: Troubleshooting High Loads On Linux Servers It mentions high loads, but disk I/O is also addressed. Thank you.
