I'm a professional sysadmin in the Research Triangle Park area of North Carolina. I've been doing sysadmin work since 1996, I've worked for a smattering of companies including Red Hat, two academic institutions, a regional bank, and now a rail transportation and logistics company.

comment Filessystem sizing issues on root
The last time I used resize2fs, it could grow filesystems online but it couldn't shrink them online. Even if it can now (which wouldn't completely surprise me), I'm enough of a paranoiac to suggest you shrink only when unmounted anyway.

comment Sendmail Undeliverable Redirection?
When you invoke sendmail, you can append a -f<sender address> option in most languages / instances / environments. It doesn't have anything to do with sendmail configuration, only invocation. It does, however, depend on where you're invoking sendmail from.

comment maillog “No route to host” error
There doesn't have to be an MX - mail can use A just as well. Does the name "subdomain.example.com" resolve to the IP of the computer you're trying to send to? Reverse DNS doesn't matter as much, if at all.
