Set From header

[iandunn]

On one of my installations, the From header isn't being sent to the SMTP address, so it's defaulting to wordpress@[domain-name], and replies fail because that address doesn't exist. I'll try to find some more details, but wanted to note the issue.

I deleted the SMTP account, then re-added it, and it's working now, so I'm guessing that this was causing by the shift in account credential storage. My sandbox probably had the account created before the shift.
