ISPC 3.0.0.9 & DynDNS = email problems ???
 
Hi

Linksys router (DMZ)
Server - Debian Lenny
ISPConfig 3.0.0.9 installation ( fresh & used ispconfig instructions )
5 DynDNS Domains
5 Clients ( so far :) )


Everything is running fine but the emails and I don't know where to look for what. Control panel "Monitor" shows all Services are online.

I had this server sending mails before ISPConfig but no clue whats going on here right now.

so please help or tell me where to look
thanks for help

All major email providers like google, hotmail, yahoo etc. block emails that are sent from a dynamic IP address, so this is no problem with your ispconfig setup. Either you put your server in a datacenter with a static IP or you have to use a axternal mailserver and relay your emails trogh this external server.

I kinda disagree on this one at least i hope it
 
Sorry but this domain changes it's IP once in a while not every day.

And before i installed ispconfig i had several sites running on that server and i got emails from that sites and also other users. ( for example Dupal site users could register and got their passwords per mail.)
Same Server - same ISP - same DSL-line

so i think its not that simple or something is mis-configured because I also can't reach the webmail for no account

and i found that entry in the Mail-Warn - Log:

Mar 1 07:12:50 Qriznizz postfix/smtpd[27550]: warning: 123.204.218.198: hostname 123-204-218-198.adsl.dynamic.seed.net.tw verification failed: Name or service not known

on the other hand i found proof of what you're saying in the Mail-Queue:

qriz@gmx.de

(host g.mx.mail.yahoo.com[209.191.118.103] refused to talk to me: 553 Mail from 68.204.153.70 not allowed - [80])
*********@yahoo.com

but what is that www-data@my.server.dyndns.net ? is that supposed to be that way?

ok Thanks for your help anyways

The errors you got are exactly caused by the problem I explained you above. Yahoo and other servers are not accepting emails from your server because it uses a dynamic IP address.

This is a common problem and the reson why mailservers are normally not run on a dsl line. I listed the two solutions for your problem in my first post.

Take a look here on how to configure your email server to relay emails trough a external mailserver:
