As others pointed out your SMTP relay has probably changed something. Looks like they chagned their advertised authentication mechanisms. I don't know if swaks tells you which authentication mechanism it used in it's output, but you could try specifying an auth-type and see if you get through. The parameter for digest-md5 would be: swaks -s smtp.strato.de ...

To do what you said, you had to set the default transport to the port 587. It can be done with a default_transport = smtp:587 But it won't work, because most SMTP servers of the world simply don't have an open port 587. What you could do: you had to get an SMTP relay who were accepted your mails (on a port differing from 25), and allowed them to go out of ...

I don't know for certain, if Pigeonhole implements client SMTP AUTH, but I found no setting for it. On the other hand, you can use a sendmail script instead of SMTP to circumvent that limitation. See: # Binary to use for sending mails. #sendmail_path = /usr/sbin/sendmail # If non-empty, send mails via this SMTP host[:port] instead of sendmail. ...

You sated that you have created a send connector, if you are allowing a relay through then you want to create a receive connector. You can use these instructions but I suggest you at least secure it to just the IPs of the servers you control. http://technet.microsoft.com/en-us/library/bb232021%28v=exchg.141%29.aspx To create a Receive connector on a ...

How can I tell postfix to redirect E-Mails dependent on the network IP, the E-Mails come from? So I could say "relay all E-Mails from [Customer A IP] to Relayhost A. You can use postfix access maps and apply FILTER action to specific client. For example Costumer A has IP 192.168.1.168, then add this to smtpd_*_restriction (for example: ...

It may be that cut and paste messed something up, but when I see the last line of the M4 macro it looks like some incorrect formatting/type-setting has taken place: FEATURE(`nullclient’, `server.example.com’) dnl The feature should only be surrounded single backtick (accent grave, &#96) and ' (acute accent, &#180) rather than what looks like an ...

You may use transport_maps in main.cf to specify optional transport map for per recipient relay and transport.

Your mynetworks directive is not valid. This setting controls which IP address ranges Postfix will allow relaying from. It should consist only of your internal servers and networks. It reads: mynetworks = all,localhost This is obviously not a list of IP addresses or CIDR ranges. Change it to reflect the actual addresses of the servers/networks which ...
