Hello exim-users,
I've just been struggling with the syntax aof a condition for my
check_helo acl. What I'm using now is:
begin acl
check_helo:
# If remote host greets with an IP address, reject connection:
deny message = REJECTED - Bad HELO - IP address not allowed ($sender_helo_name).
condition = ${if isip {$sender_helo_name}{true}{false}}
# Deny if the HELO pretends to be this host:
deny message = You pretend to be $sender_helo_name, but that's me.
condition = ${if or { \
{eq {${lc:$sender_helo_name}}{server.linau.de}} \
{eq {${lc:$sender_helo_name}}{www.linau.de}} \
{eq {${lc:$sender_helo_name}}{localhost}}}{true}{false}}
# Otherwise accept connection:
accept
As have listed all local domain names in a file using
domainlist local_domains = /etc/exim4/domainfiles/local-domains.txt
I'm wondering how to include either the local_domains variable or the
local-domains.txt file in my condition expression.
I've already tried constructing an expression using "lsearch", but
unfortunately, I'm not yet familiar enough with the corresponding
syntax.
I appreciate any help - mabe someone can just point me to the
corresponding chapter of the exim specs...
Regards & thanks in advance,
Christian Schmidt
