Topic: email reminders rejected by gmx.de and web.de

Hi folks,

since a few days mails from the calendar are rejected by gmx.de and web.de.
Both mail providers are very common in Germany.

The response is:
Reporting-MTA: dns; XXXXXX.your-server.de

Action: failed
Final-Recipient: rfc822;XXXXXX@gmx.de
Status: 5.0.0
Remote-MTA: dns; mx00.emig.gmx.net
Diagnostic-Code: smtp; 554-Transaction failed
554-Reject due to policy restrictions.
554 For explanation visit XXXlink not allowedXXX

Anyone else having this problem?
Any solution?

I am using phpmail.
Other php-mails from our server seem to work properly.

Best Wishes

Hi again,

I fiddled around a bit in messaging.php and found a workaround.
It seems the mentioned mailproviders don't like the 'To:' parameter being empty.
So I hardcoded a mailaddress into line 174 instead of 'null'.
(can be the admin mail address)

Now the mails are accepted.

Hello Highlow,

Thanks for reporting this solution. Email problems can be a nuisance and often hard to analyze and solve.
I will change this for the next calendar version and also put the calendar (admin) email address in the 'To' field.
