I've been running SA3 + amavisd-new on my servers for a while and the upgrade of
pyzor didn't have that effect on me. Still, I've looked into this some.
Parsing the error message actually isn't that bad, amavis failed in the
check_mail function, while it was attempting to forward the mail:
<snip>
# THIRD: now that we know what to do with it, do it!
if ($forward_method ne '') { # message must be delivered explicitly
$which_section = "forwarding";
ensure_mime_entity($msginfo,$fh,$tempdir,[EMAIL PROTECTED]); #need
header
# will forward only to those recipients not yet marked
# as 'done' by the above content filtering sections
for (;;) {
my($hdr_edits) = Amavis::Out::EditHeader->new;
$hdr_edits = add_forwarding_header_edits_common(
$conn,$msginfo,$hdr_edits,$hold,$any_undecipherable,
$virus_presence_checked,$spam_presence_checked);
my($done_all);
my($recip_cl); # ref to a list of similar recip objects
($hdr_edits,$recip_cl,$done_all) =
add_forwarding_header_edits_per_recip(
$conn,$msginfo,$hdr_edits,$hold,$any_undecipherable);
last if [EMAIL PROTECTED];
$msginfo->header_edits($hdr_edits);
mail_dispatch($forward_method,$conn,$msginfo,0,
sub {my($r)[EMAIL PROTECTED]; grep {$_ eq $r}
@$recip_cl} );
last if $done_all;
}
}
prolong_timer($which_section);
</snip>
The 'Can't rewind mail file' part is an amavis thing. Throughout amavis makes
calls like '$msg->seek(0,0) or die "Can't rewind mail file: $!";' This also
tends to appear in functions that send the mail from amavis, so it's probably
likely that mail_dispatch() calls a function that calls a seek().
Basically, I don't really think at this point that it's a pyzor issue, as pyzor
doesn't give errors like that (the seek errors are different as per #295852).
In addition I can't seem to reproduce it, so if you could either give me details
of your setup and/or jack the debug level way up on amavis that would enable me
to give you some more help and hopefully solve this.
