Re: [exim] ACL to stop an account to send email

2018-02-03 Thread Luciano Rinetti 
To avoid the intricate grammar of the acl rules, i found this simple
suggestion:
https://www.tekovic.com/exim-acl-for-blocking-certain-senders
It worked the first time, the denied sender, can read its mailbox, but
it receive an "Administrative prohibition."
message when it try to send an email.
Of course i restarted exim4 with:
kill -HUP `cat /var/run/exim4/exim.pid`

Hope this may be helpful to others.

Re: [exim] ACL to stop an account to send email

2018-02-03 Thread Luciano Rinetti 
Thank you Marius,
i think the b) option is the one i choose with acl_check_out:
Let suppose the account is:
xyz@domain.com
how should be wrote the acl in the ACL configuration section of exim.conf ?

a) your courier server has nothing to do with exim, so : yes, you can.

b)

I your case, these acls seems to be the best attempts:

acl_check_auth:
acl_check_mail:
acl_check_rcpt:

If the account uses smtp-auth , just deny it there.
If the account uses a fixed sender address, use check_mail
and you guessed it, if you need to stop mails to specific recipients,
use check_rcpt

Any of these acls has unique variables that might come handy. Check with
the Exim-Docs

hint:

deny condition ${if eq{$..}{"sen...@blah.xx"}{yes}{no}}

Find out how that account is sending mail and block it. there's
probably some evidence in the received header.
