Re: [exim] Smarthost condition by h_From header variable

Dear Heiko,

I've tried envelope_sender but Exim says unknow variable.

The goal is: We would like to use a separate smarthost for specified
domains on real sender ( envelope_sender ) which is in the From: header.

For example: many users use webmail where the sender is www@???,
the real sender is user@???. There is no problem with MUAs
but webmail users always send mail with sender www@??? so the
real sender is in the From: header. I need to get this address somehow.

If I try this:

smarthost:
driver = manualroute
debug_print = Domain: From: ${local_part}@${domain}, Sender: $header_From
domains = ! pgsql;SELECT nev FROM domain WHERE nev =
'${quote_pgsql:$domain}' AND local = 1
condition = ${if match_domain{${domain:$h_From:}}{domain.com}{yes}{no}}
transport = remote_smtp
route_data = XXX.XXX.XXX.XXX
no_verify
no_more

It seems it works well. When $h_From is 'domain.com' it send to
smarthost if not it doesn't sends to smarthost but uses direct smtp.

But with an SQL it always calls smarthost router:

smarthost:
driver = manualroute
debug_print = Domain: From: ${local_part}@${domain}, Sender: $header_From
domains = ! pgsql;SELECT nev FROM domain WHERE nev =
'${quote_pgsql:$domain}' AND local = 1
condition = ${if match_domain{${domain:$h_From:}}{lookup pgsql{SELECT
nev FROM domain WHERE nev = '${domain:$h_From:}' AND relay = 1}{yes}{no}}}
transport = remote_smtp
route_data = XXX.XXX.XXX.XXX
no_verify
no_more

If I run the SQL-query manually it works fine: gives me back that expected.

I understand that I do something wrong but what?

Thanks,

János
