Why everyone feels they need regular expressions for this is a mystery.
/etc/postfix/sender-access:
top REJECT I employ crude anti-spam measures
.top REJECT I employ crude anti-spam measures
cam REJECT I employ crude anti-spam measures
.cam REJECT I employ crude anti-spam measures
...
main.cf:
texthash = texthash:${config_directory}/
smtpd_sender_restrictions =
check_sender_access ${texthash}sender-access
or directly in main.cf:
main.cf:
smtpd_sender_restrictions =
check_sender_access inline:{
{ top = REJECT I employ crude anti-spam measures }
{ .top = REJECT I employ crude anti-spam measures }
{ cam = REJECT I employ crude anti-spam measures }
{ .cam = REJECT I employ crude anti-spam measures } }
or an indexed table (with same sender-access file, after "postmap"):
main.cf:
# "cdb" is better when available
default_database_type = hash
indexed = ${default_database_type}:${config_directory}/
smtpd_sender_restrictions =
check_sender_access ${indexed}sender-access
Whatever you choose, regular expressions should last or on your list, or
not at all. A very small fraction of mortals are capable of using
regular expressions correctly.
Thanks for everyone who has responded. This (directly in main.cf)
appears to be the answer that works for me and is much simpler.
I tried the suggested regexp before this one and still got the same error.
The error was:
