Description:	If the `mailcmd` parameter refers to a command or script that does not exist, all voicemail messages are silently dropped. [At the time|https://github.com/asterisk/asterisk/blob/16.12/apps/app_voicemail.c#L14020] the value is assigned, it should also check for its existence and executability. If either check fails, an error should be generated and Asterisk should fall back to its default behaviour.

I don't see anything that checks the result of executing mailcmd so I don't see how it failing would lose any data. By: Michael Newton (miken32) 2020-09-01 13:33:46.149-0500 Sorry, I didn't mean the voicemail recordings aren't saved, I'm just talking about the email. There's no fallback for a missing script, so the email is never sent. No errors show up in the log.
