So... what is the proper configuration of the transport file, so that all mails are sent through my ISP relay host, with some exceptions, like local mail?

That part I solved in the transport file with this syntax: lists.sourceforge.net : users.sourceforge.net : localhost : valinor : nimrodel.valinor : .localhost : .valinor : .nimrodel.valinor : #Default: * smtp:[smtp.telefonica.net]

Hola Carlos,

I think you need to look up the sender_dependent_relayhost_maps parameter in postfix.

Ah! Yes, that's it. But this feature has almost no documentation. The only text I found is in "RELEASE_NOTES-2.3": - - Sender-dependent smarthost lookup tables. The maps are searched with the sender address and with the sender @domain. The result overrides the global relayhost setting, but otherwise has identical behavior. See the postconf(5) manual page for more details. Example: /etc/postfix/main.cf: sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay And the postconf(5) manual page doesn't clarify much: sender_dependent_relayhost_maps (default: empty) A sender-dependent override for the global relayhost parameter setting. The tables are searched by the envelope sender address and @domain. This information is overruled with relay_transport, default_transport and with the transport(5) table. For safety reasons, this feature does not allow $number substitutions in regular expression maps. This feature is available in Postfix 2.3 and later. But there is no sample "sender_relay" file to guide me :-/ I have just googled that parameter and found many people asking for a solution for the very same problem I have: sending to diferent smtp relay hosts depending on the "from" address, and using the correct auth id each time for each server, based as well on the from address. I have a lot to read... - -- Cheers, Carlos E.

I liked your previous configuration with relayhost better. This is exactly the same, only the configuration needs much more lines. (^-^)

Except that exceptions did not work, or I did it wrong. I didn't find a way to handle the "users.sourceforge.net" line.

Simple: domain or user as key and relayhost as result. That's why it is called "...relayhost_maps" (^-°)

I guess! But sometimes I very thick headed O:-)

A sender-dependent override for the global relayhost parameter setting. The tables are searched by the envelope sender address and @domain. My example uses the extreme (two senders that use the same relayhost but different authentication.

Yes, I also need that.

Strange... Anyway, here's a sample I used to verify that it works:

/etc/postfix/main.cf: sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/smtp_relayhost_auth smtp_sasl_security_options = noanonymous smtp_sender_dependent_authentication = yes

Ok, except for the "sender_dependent_relayhost_maps" I had the same thing. And "smtp_sasl_security_options" was empty.

/etc/postfix/sender_relayhost user1@gmx.de [mail.gmx.de] user2@gmx.de [mail.gmx.de]

I'll try right now.

/etc/postfix/smtp_relayhost_auth: user1@gmx.de user1@gmx.de:password1 user2@gmx.de user2@gmx.de:password2

[...] It works! Thanks :-) I think we talked about this time ago, but I most have lost my notes, or didn't save them properly. Sounds familiar. I configured my postfix with no default relay, so if I don't specify one my postfix will try to send itself. If the sender matches, then it will use the addecuate relay. And, if I understand correctly, if I define a particular transport rule, it will override the sender_relay rule. Next thing is to check what will happen with bounces. Or wait. - -- Cheers, Carlos E.

Either they (telefonica) require that you use their domain as sender domain or they fubared their dns servers and used something like reject_unknown_sender_domain with broken dns. Only the postmaster of smtp.telefonica.net can tell you.

It seems the former. I was told that they had dropped this policy, and for some time I was able to relay some mail, but either it didn't last, or it is random. As to asking the postmaster, that's impossible: you have to phone customer service which is attended by very nice voices that know nothing aside from the very usual.

...

So I want to attempt sending again from my local postfix (yes, on dynamic IP). I remove the "relayhost = [smtp.telefonica.net]" line, and edit the transport file:

localhost smtp: valinor smtp: nimrodel.valinor smtp:

Don't you want to send mails for these recipients to your own host? In that case you should tell your box to use "local:" as transport.

Though I wonder why that should be necessary. Postfix uses the default transport for the domain class if the domain is member of mydestination, relay_domains or virtual_mailbox_domains:

mydestination local_transport relay_domains relay_transport virtual_mailbox_domains virtual_transport

I got that part running this way: lists.sourceforge.net : users.sourceforge.net : localhost : valinor : nimrodel.valinor : .localhost : .valinor : .nimrodel.valinor : #Default: * smtp:[smtp.telefonica.net] Now, what I want to get working is this: sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay But there is no sample sender_relay file, so I'm stuck. I'm googling it, and so far what I have found are questions but no answers. I only found this: sender_relay: @example.com [thisrelay.example.com] @example.net [thatrelay.example.com] Some people have complained that with this setup they have another problem: when an email is rejected, the bounced mail is attempted to be sent through the relay host (empty envelope from) and it is dutifully rejected by the relay, obviously. The bounced should use the local transport instead. So far I haven't deduced how to avoid that (and I have suffered that problem in my tests, too). For instance, I found a thread in <http://tech.groups.yahoo.com/group/postfix-users/messages/206197?threaded=1&m=e&var=1&tidx=1> where finally they say: ] If I can do it, anybody can. Go back about two weeks in the archives. ] Victor gave me some pretty good advice on how it was done. and I'm trying to locate that message with no luck so far. ...

Yes, this is possible with "sender_dependent_relayhost = yes", but please define first, what sender address should use what host as nexthop.

That's no problem. Each from address gets a different relay host, except two redirectors that have none and I have to attempt to send from my postfix directly. The above solution in "transport" is a temporary workaround while I find some docu about "sender_relay" - -- Cheers, Carlos E.

Er.. hello?!? I just gave you a complete, tested and working example in my previous post. Granted, my file wasn't named sender_relay (this is an ARBITRARY name you can decide yourself!). My example used the file name "sender_relayhost".

Sorry O:-) That was in another mail I saw later.

Once again:

/etc/postfix/main.cf: sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/smtp_relayhost_auth smtp_sasl_security_options = noanonymous smtp_sender_dependent_authentication = yes

yep, yep.

/etc/postfix/sender_relayhost user1@gmx.de [mail.gmx.de] user2@gmx.de [mail.gmx.de]

/etc/postfix/smtp_relayhost_auth: user1@gmx.de user1@gmx.de:password1 user2@gmx.de user2@gmx.de:password2

Aye, aye, sir! :-) I got it working a minute ago.

But there is no sample sender_relay file, so I'm stuck. I'm googling it, and so far what I have found are questions but no answers. I only found this:

See above (^-^)

Documented is the parameter "sender_dependent_relayhost_maps".

Yep, the parameter is documented, what is not is a sample file, as they have for transport, virtual, etc.

Grin! You need sleep. (^-°)

Why do you (ab)use the Envelope From header to set the from address? Use the body From: in its stead, then your ISP won't complain. Set the envelope 'Mail From:' to whatever your ISP wants.

I don't change the envelope from in any way, none of my mail programs allow me to change it. Therefore, I assume both the envelope from and "normal" from are the same. - -- Cheers, Carlos E.

Are you saying your email apps don't support a reply to address?

No, not at all. I say that I can't manually set the "envelope from" address. The only MUA that allows this is mutt. - -- Cheers, Carlos E.
