hi guys,
i'm getting a load of spam mails through with ~90%
return@abc-xyz.xx|
return@def.qwer.xx|
return@uvw.iop.xx
sender domains are always different, but the "return@" pretty constant ...
is it possible to block return@*.* or at least return@*.com or return@*.pl ?
i've tried
- efa.PNG (885 Bytes) Viewed 3665 times
but it doesn't seem to work ...
thanks in advance

Blacklist method (?)
From: return
To: default
Haven't tried this myself, but this might work. Not sure if this will catch the username portion of the email or not.
Another idea is create a Spamassassin rule and give it a high score

hi shawniverson,
thanks for your help.
i've tried this:
- efa.PNG (13.15 KiB) Viewed 3650 times
but it doesn't work.
return@xyz.com mails are still coming through...
any other way how can i solve this with web ui ?
i'm afraid creating spam assassin rules is above my skills (read about it there
https://wiki.apache.org/spamassassin/WritingRules )

Edit /etc/mail/spamassasin/local.cf and add this:
Code: Select all
header FROM_RETURN From =~ /return\@/i
score FROM_RETURN 10
describe FROM_RETURN return@example.org detected

hi shawniverson,
thanks for your input.
i don't even know how to add this rule to the config:
- efa.png (20.73 KiB) Viewed 3636 times
i can't open the .cf file with vi command, i cant't change directory with cd /etc/mail/spamassasin/
i can't even list directories ...
sorry, as i said i'm a gui/menu guy ...
