Hi

I have problem with mails sent via www. I received the following error:

Feb 25 19:10:24 plesk postfix/qmgr[17491]: E397129306D5: to=<x@x>, relay=none, delay=0.9, delays=0.69/0.22/0/0, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with 127.0.0.1[127.0.0.1] while sending end of data -- message may be sent more than once)

Some idea?
