Is this for "NO FILE" or "Number Of FILE" (with a final "S" missing) ? if it's the latter, call it NOFILES to avoid the confusion.

@gballet no, don't revert changes to mailserver.go, I think it is fine as is.

Regarding NOFILE - I think this is how open file descriptors are called in Linux - for example https://wiki.archlinux.org/index.php/Limits.conf#nofile

Also it is pretty clear what this is doing based on the line above, and the commands below.

I don't have strong feelings about the name of the var, I can change to whatever if necessary.
