Look at the log of the mail server that rejected the post for more details. The log message would be notice-level similar to the following:
"!username (user #x) cannot post on sub (reason: why)"

> /home/sbbs/ctrl/alias.cfg has this entry

Hopefully you have a space before "sub:" ?

Look at the log.
