Resolved Horde stopped sending mail after upgrade 12.5.30

SysInt

New Pleskian
Since the update of plesk 12.5.30 all my customers can't send mail any more from the mailclient horde (2.6). The error they get is

"There was an error sending your message <domain> ESMTP"

Mail from site-forms are still working.

I am using qmail.

In the maillog i found a statement
relaylock[]: mail from 0000:0000:0000:0000:0000:0000:0000:0001 (undefined)

Does anyone have any idea where to look?

Thanks IgorG, done that makes no difference.

BTW: my white-list is correct

127.0.0.1 and ::1 is present
 
Do you have "disable_functions" directive in the /etc/php.ini file?
 
Try to comment this directive and restart Apache.
 
Hé IgorG
Didn't make a difference. It keeps saying relaylock on 0000::0001 in the maillog
 
Yes!!! that did the trick. With Postfix MTA everything works again.

But, i remenber that a few years back i had to change to qmail because Postfix didn't work. There is a cat and mouse play going on :)

Thank you so much.
