I did a test with the parameter "$encode_header_key" - but it did't fixed my problem. It reduced the two "Received:" line too one - but the provider is still blocking me when I'm sending via SM (via Outlook it stiil works). My header looks know like this (just the "Received:" part): Send from the internet: Received: from webmail.domain2.dnsalias.org ([192.xxx.xxx.xx2]) by mail.domain2.dnsalais.org with hMailServer ; Sun, 24 Aug 2008 19:00:49 +0200 Send from my local network: Received: from webmail.domain1.local ([192.xxx.xxx.xx2]) by mail.domain2.dnsalais.org with hMailServer ; Sun, 24 Aug 2008 18:49:26 +0200 So my question is still - how to modify the header information: --> "from webmail.domain2.dnsalias.org" --> "[192.xxx.xxx.xx2]" Does anybody know the paramenter - and where to modify it? Thank you in advance Ralf PS1: The host name of the server is fully qualified --> serverxxx.domain1.local. And in combination with Outlook and hmail it works fine. Just with SM and hmail I have the problem since my mail provider changed his policy. PS2: I cound find the variable "" - is it set in PHP or SM? PS3: "$domain" is set to "domain1.local" ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
