Hi, one more thing is there. As gogle seems that all mails from my domain are Spam, I'd like to add the DKIM service. I tried it, but then no mails reach their destination. So I disabled it again. I searched the forum and other places and found that there is no public key available: Code: default._domainkey.mydomain => invalid (public key: not available) I know that the public key must be handed over to the DNS, but I have none (DNS) on my server, and I can't access (at least not to my knowledge) the domain server of my provider. I guess there are ways to do that, but I need once again a little help from my friends... Unfortunately, even though I disabled DKIM, still mails aren't sent away. I have the following log entry: Code: Oct 14 15:58:20 mydomain postfix/smtpd[13277]: connect from xxxxxxx.dip0.t-ipconnect.de[xxx.xxx.xxx.xxx] Oct 14 15:58:20 mydomain postfix/smtpd[13277]: NOQUEUE: filter: RCPT from xxxxxxx.dip0.t-ipconnect.de[xxx.xxx.xxx.xxx]: <me@mydomain>: Sender address triggers FILTER amavis:[127.0.0.1]:10026; from=<me@mydomain> to=<receiver@hisdomain> proto=ESMTP helo=<[xxx.xxx.xxx.xxx]> Oct 14 15:58:20 mydomain postfix/smtpd[13277]: 5A9A94F8987: client=xxxxxxx.dip0.t-ipconnect.de[xxx.xxx.xxx.xxx], sasl_method=PLAIN, sasl_username=me@mydomain Oct 14 15:58:20 mydomain postfix/cleanup[13282]: 5A9A94F8987: message-id=<229fbb98-a20a-893e-57e1-a73ec6fe8222@mydomain> Oct 14 15:58:20 mydomain postfix/qmgr[13156]: 5A9A94F8987: from=<me@mydomain>, size=4492, nrcpt=1 (queue active) Oct 14 15:58:20 mydomain postfix/smtp[13159]: connect to 127.0.0.1[127.0.0.1]:10026: Connection refused Oct 14 15:58:20 mydomain postfix/smtp[13159]: 5A9A94F8987: to=<receiver@hisdomain>, relay=none, delay=0.12, delays=0.12/0/0/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10026: Connection refused) Oct 14 15:58:21 mydomain postfix/smtpd[13277]: disconnect from xxxxxxx.dip0.t-ipconnect.de[xxx.xxx.xxx.xxx] To be precise: In the client, it says the mail has been sent successfully. But the receiver never receives the mail.
I discovered last night that, even though I disabled DKIM in the UI, all the related lines in amavisd.conf were still active. After commenting them out, E-Mail receiving and sending worked again. I consider this a bug...
You have to add the dkim key at your provider when you don't run your own name server. Ask the support of your provider on how to add DNS records to his system and then get the key from mail domain settings in ISPConfig and add it at your provider. I'll try if I can reproduce that here.
