We just got bitten by a strange problem with our mynetworks-file. In
main.cf we have mynetworks = /etc/postfix/mynetworks, and the
/etc/postfix/mynetworks has been used to both include and exclude
networks for ages... using the format:
#### BLACKLISTING ###
## Only blocked systems in this block
!92.345.67.0/24 # BLACKLISTED - 17.09.10
!98.102.24.28/32 # BLACKLISTED - 11.06.09 - Some other company AS
!82.110.89.38/32 # BLACKLISTED - 01.10.10 - Some company AS
#<snip>#
## Add openings beneath this point
10.0.0.0/8
127.0.0.0/8
#<snip>
Today we forgot the "S" in "AS", i.e.:
!9.11.21.12/30 # BLACKLISTED - 12.05.11 - Another company A
instead of our normal:
!9.11.21.12/30 # BLACKLISTED - 12.05.11 - Another company AS
and suddenly postfix stopped working. It was complaining about:
postfix/smtpd[29113]: fatal: bad address pattern: "A"
So I guess our usage of comments in this file is wrong (ooops). Could
someone help us with what the rules are for this file? Are lines starting
with # interpreted as comments? Are the any way of introducing comments on
the same line as a rule ?
