Hi Dennis, Thank you very much and please excuse the delay but I had too many open issues...
Now postfix delivers everything @ that.domain to their mailer, also for the user I manage locally: Mar 4 12:24:07 server6 postfix/trivial-rewrite[7155]: warning: do not list domain that.domain in BOTH mydestination and virtual_alias_domains Mar 4 12:24:07 server6 postfix/smtpd[7196]: E4F484383F: client=localhost[127.0.0.1] Mar 4 12:24:07 server6 postfix/cleanup[7154]: E4F484383F: message-id=<20120304112403.0d36343...@server6.xxx.yyy.zz> Mar 4 12:24:07 server6 postfix/qmgr[7098]: E4F484383F: from=<r...@server6.xxx.yyy.zz>, size=1225, nrcpt=1 (queue active) Mar 4 12:24:07 server6 postfix/smtpd[7196]: disconnect from localhost[127.0.0.1] Mar 4 12:24:07 server6 postfix/trivial-rewrite[7155]: warning: do not list domain that.domain in BOTH mydestination and virtual_alias_domains Mar 4 12:24:07 server6 postfix/smtp[7156]: 0D36343840: to=<my.user@that.domain>, relay=127.0.0.1[127.0.0.1]:10024, delay=4.9, delays=0.02/0.02/0/4.9, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as E4F484383F) Mar 4 12:24:07 server6 postfix/qmgr[7098]: 0D36343840: removed Mar 4 12:24:08 server6 postfix/smtp[7197]: E4F484383F: to=<my.user@that.domain>, relay=that.domain[xxx.xxx.xxx.xxx]:25, delay=0.84, delays=0.01/0.01/0.32/0.5, dsn=2.0.0, status=sent (250 Ok. 4F5350D8.00001E6E) Mar 4 12:24:08 server6 postfix/qmgr[7098]: E4F484383F: removed I am sure I did something wrong, but I am still too much of a bloody newbie in matter postfix to be able to discover what... :-( These are my settings: main.cf: virtual_alias_domains = hash:/etc/postfix/virtual, /etc/postfix/local-host-names mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, domain1, domain2, domain3, ..., that.domain alias_maps = hash:/etc/aliases sender_dependent_relayhost_maps = hash:/etc/postfix/sender_dependent_relayhost transport_maps = hash:/etc/postfix/transport ------ relay_recipients: @domain1 OK @domain2 OK @domain3 OK ... my.user@that.domain OK ------ sender_dependent_relayhost: my.user@that.domain smtp:[exchange.ser.ver] ------ Transport: domain1 smtp:[exchange.ser.ver] domain2 smtp:[exchange.ser.ver] domain3 smtp:[exchange.ser.ver] ... that.domain smtp:[ that.domain] .that.domain smtp:[ that.domain] ------ /etc/aliases: ## aliases for the Exchange Server on server1 ... myuser: my.user@that.domain I would be very grateful fon any hint...

Change the entry for domain.diffi.cult and .domain.diffi.cult in your transport map to the MX for this domain: domain.diffi.cult smtp:domain.diffi.cult .domain.diffi.cult smtp:domain.diffi.cult For myu...@domain.diffi.cult add a sender_dependent_relayhost_maps (http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps) in your main.cf and point your user to your exchange: myu...@domain.diffi.cult smtp:[exchange.ser.ver] Dennis [..] ***************************** ***************************** This e-mail and any files transmitted with it may contain confidential and/or privileged information.
