That is it! Thank you. I have commented out lines:
/.../
-o content_filter=filter:dummy
/.../
filter unix - n n - - pipe
flags=Rq user=vacation argv=/home/vacation/mail-filter -f ${sender} --
And emails are send only once.
Now I have to analyse this vacation filter.
But, as I understand it, according to master.cf it is run AFTER filtering, not
before?
