Well, they have to tell people you’re not in the job anymore, and “left to pursue other opportunities” actually suggests that you quit, which is what I’d like my professional contacts to believe. I’d prefer that to “XXX is no longer with the firm.”

Yes, I’m sure the firm/company/agency will take care of this to make sure your e-mails are directed to whomever is taking over your work.

As others have mentioned, this should be covered in the exit process.

No, it’s for families where I live at home, sorry.

Might want to swallow your pride here. ;) I can’t think of a way to write the OoO without either saying exactly what your new job is (and thereby implicitly encouraging the e-mailer to contact you there instead) or sounding like you are trying too hard to hide that you were in fact canned.

For reference, I quit, and my OoO was something like “Thank you for your e-mail. I no longer work at Company A. Please contact [Boss] at [Contact Info] if you need any assistance.”

I once received an OoO where the “sender” said he was happy to finally be free of the living hell that was his job at Company A. So he clearly left of his own free will, but I wasn’t sad to see him go. (He was pretty casual and careless even before he quit.)

Just stick with canned; honestly, people change jobs all the time so I wouldn’t think twice about why someone left and really just want to know who else to contact about the matter.
