Hi,

I tried to use your DKIM Signature Test Tool, but unfortunatly your mailserver (mail.appmaildev.com) tries to identify with an untrusted certificate, so your server got greylistet.

Here is a short excerpt from my postfix logs:
Code:

Jan 24 13:12:40 v3-1090 postfix/smtp(20388): certificate verification failed for mail.appmaildev.com(69.89.227.121):25: untrusted issuer /CN=AdminSystem Root
Jan 24 13:12:41 v3-1090 postfix/smtp(20388): A0F2C140E6D: to=<AAAA3gcBGAcA@appmaildev.com>, relay=mail.appmaildev.com(69.89.227.121):25, delay=2, delays=0.82/0/0.86/0.31, dsn=2.6.0, status=sent (250 2.6.0  <c3d209ac8e494f3eb51adfba4c5f5bec@internal*****.de> Queued mail for delivery)


Although the message gets out your server is (of course) added to postgreys geylist so your reply doesn't get through:

Code:

Jan 24 13:12:43 v3-1090 postfix/smtpd(20468): connect from mail.emailarchitect.net(69.89.227.124)
Jan 24 13:12:45 v3-1090 postgrey(8687): action=greylist, reason=new, client_name=mail.emailarchitect.net, client_address=69.89.227.124, sender=auth-report@appmaildev.com, recipient=andromeda@wurst****.de
Jan 24 13:12:45 v3-1090 postfix/smtpd(20468): NOQUEUE: reject: RCPT from mail.emailarchitect.net(69.89.227.124): 450 4.2.0 <andromeda@wurst****.de>: Recipient address rejected: Greylisted, see http://postgrey.schweikert.ch/help/wurst****.de.html; from=<auth-report@appmaildev.com> to=<andromeda@wurst****.de> proto=ESMTP helo=<mail.appmaildev.com>
Jan 24 13:12:45 v3-1090 postfix/smtpd(20468): disconnect from mail.emailarchitect.net(69.89.227.124)


I'm trying to temporary disable greylisting on my side, but you should consider changing to a valid certificate soon.

Cheers
Dachande
