Hi Terry,
When gmail / yahoo sent email out, they will sign the email by their own
domain keys. But when these emails are forwarded from your ISP, the header
has been modified and the signature became invalid. I guess that's the
reason why your server rejects them. Try adding DKVERIFY="" to the line of
your ISP in tcp.smtp and rebuild the cdb to disable incoming checking.
Hope it helps you and good luck.
Best regards,
Bill

Hello all, first time poster here. Ive been using QT for some time now
and I've just updated to one of the more recent versions and since its
worked so well out of the box in the past for me I guess I have a lot of
holes in my ability to administate my mail system.
I currently use fetchmail to grab my emails from my ISP and forward it to
an email address I have on my own server here at home, for example fetchmail
grabs mail from my ISP "[EMAIL PROTECTED]" and then sends it off to "
[EMAIL PROTECTED]". Somewhere along the line I run into the issue
of mail getting rejected due to this. I am guessing its fetchmail causing
the issue or rather the fact that the mail is to "myisp.com" yet its being
delivered to "myhomeserver.com". I really do lack the knowledge to really
know whats going on to fix it properly.
My /var/log/qmail/smtp/current shows a bunch of errors like the
following....
qmail-smtpd: qq hard reject (qmail-dk: Cannot sign message due to invalid
message syntax. (#5.3.0)): MAILFROM:<[EMAIL PROTECTED]>
RCPTTO:[EMAIL PROTECTED]
The odd thing is, most emails get through to me, its mostly emails from
yahoo and gmail that dont get through. I've tried adding rules to
tcp.smtp and rebuilding the rules but that only makes it so that the IP's
that are whitelisted arent hard rejected but soft rejected. So fetchmail
leaves them on my ISP's mail server instead of rejecting and deleting
them. Also, there are multiple IP addresses for gmail and yahoo mail
servers which makes it harder to whitelist them.
In order to try and figure out what is casing the mail to be rejected I've
edited my tcp.smtp quite a bit.. it is currently as follows...
127.0.0.1:allow
,RELAYCLIENT="",QMAILQUEUE="/var/qmail/bin/simscan",CHKUSER_RCPTLIMIT="50",CHKUSER_WRONGRCPTLIMIT="10"
24.71.223.:allow,RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/simscan"
66.135.192.:allow,RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/simscan"
66.94.234.:allow,RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/simscan"
216.109.112.:allow,RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/simscan"
209.191.69.:allow,RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/simscan"
:allow,BADMIMETYPE="",BADLOADERTYPE="M",CHKUSER_RCPTLIMIT="50",CHKUSER_WRONGRCPTLIMIT="10",QMAILQUEUE="/var/qmail/bin/simscan"
I probably have it pretty messed up here but before I g editing it anymore
I wanted to post to this list to get some ideas on how to resolve this
situation. I also have to mention that I dont have issues with email being
send directly to [EMAIL PROTECTED], it is only when emails are
grabbed with fetchmail.
Can anyone here suggest what I might do to fix this problem other than
stop using fetchmail :) Thank you in advance for your time.
Terry Rigby
