avastfilter: Too much 'From: ' headers in the message header

Hi,

I have avast4linux and avast4mail (and libavastengine) on a gentoo-machine with qmail.

I found the following in my logs:

2010-11-26 15:12:59.064398500 tcpserver: pid 28028 from xx.xx.xx.xx 2010-11-26 15:12:59.990206500 tcpserver: ok 28028 mail.mydomain:::ffff:10.0.0.20:25 server:::ffff:xx.xx.xx.xx::53915 2010-11-26 15:13:00.024804500 qmail-smtpd 28039: connection from xx.xx.xx.xx to mail.mydomain 2010-11-26 15:13:00.024859500 qmail-smtpd 28039: enabled options: max msg size: 10485760 sanitycheck returnmxcheck blockrelayprobe rblcheck sendercheck rcptcheck qmailqueue /var/qmail/bin/qmail-scanner-queue 2010-11-26 15:13:00.091213500 qmail-smtpd 28039: RBL check with 'ix.dnsbl.manitu.net': no match found, continue. 2010-11-26 15:13:00.105657500 qmail-smtpd 28039: RBL check with 'cbl.abuseat.org': no match found, continue. 2010-11-26 15:13:00.383489500 qmail-smtpd 28039: RBL check with 'sbl.spamhaus.org': no match found, continue. 2010-11-26 15:13:00.514142500 qmail-smtpd 28039: RBL check with 'bl.spamcop.net': no match found, continue. 2010-11-26 15:13:00.748245500 qmail-smtpd 28039: mail from: webmaster@www.sender.tld 2010-11-26 15:13:00.777578500 qmail-smtpd 28039: rcpt to: me@mydomain 2010-11-26 15:13:04.111353500 avastfilter: Too much 'From: ' headers in the message header 2010-11-26 15:13:04.113409500 X-Qmail-Scanner-1.25st:[quinx129078078072428041] Unable to open pipe to /usr/bin/avastfilter [65] (#4 .3.0) - 2010-11-26 15:13:04.120396500 X-Qmail-Scanner-1.25st:[quinx129078078072428041] Unable to close pipe to /usr/bin/avastfilter [65] (# 4.3.0) - Illegal seek 2010-11-26 15:13:04.125448500 qmail-smtpd 28039: message temporarly not accepted because: qq trouble creating files in queue (#4.3. 0)

What does “Too much 'From: ’ headers in the message header” mean? How can I solve this?

Greetings!

Hallo, it means just what it says - there were more than one “From:” field in the header - which is strange anyway (just check the particular mail).
