Details:

Hi,

This worked yesterday, but does not work today: I have my
mail account at Strato (one of the two largest German
providers, who hosts millions of email accounts). I wish to
send email to a gnu.org mailing list from this account, but it
leads to the following error:

   ----- The following addresses had permanent fatal errors -----
<address@hidden>
    (reason: 550 Callback setup failed while verifying <address@hidden>
Called:   192.67.198.48 Sent:     MAIL FROM:<> Response: 503 5.1.8 Postmaster
not allowed The initial connection, or a HELO or MAIL FROM:<> command was
rejected. Refusing MAIL FROM:<> does not help fight spam, disregards RFC
requirements, and stops you from receiving standard bounce messages. This
host does not accept mail from domains w)

   ----- Transcript of session follows -----
      ... while talking to mx10.gnu.org [199.232.76.166]:
      >>> RCPT TO:<address@hidden>
 <<< 550 Callback setup failed while verifying <address@hidden> Called:  
192.67.198.48 Sent:     MAIL FROM:<> Response: 503 5.1.8 Postmaster not
allowed The initial connection, or a HELO or MAIL FROM:<> command was
rejected. Refusing MAIL FROM:<> does not help fight spam, disregards RFC
requirements, and stops you from receiving standard bounce messages. This
host does not accept mail from domains w
   550 5.0.0 Mailbox unavailable

The IP address 192.67.198.48 is mailin.webmailer.de,
which is Strato's mail server.

It appears that a particular configuration of mx10.gnu.org
causes it to reject the mail delivery attempts from
mailin.webmailer.de.
