Problems receiving mail in qmail


I can send email to client-x, but the client-x can't send us your email.
The client-x receive an email error with the following message:

"553 sorry, your HELO host name has been denied (#5.7.1)"

My mail server is qmail (1.03 version) on Red Hat Enterprise Linux Server release 5.
The client-x have Microsoft Exchange and Sophos Email Appliance
( The Email Appliance is an appliance for filtering email.)

The /var/qmail/control/badhelo file on my server doesn't have For me, is not a badhelo.

Seven month ago I installed qmail-103.patch from
# patch -p1 < qmail-103.patch
# make setup check

I don't know if I need install another patch for qmail to resolve this problem.

I did the following test from my server :

[root@srv ~]# telnet 25
Connected to
Escape character is '^]'.
250-SIZE 22777216
250 ok
RCPT NOTIFY=success,failure
553 sorry, your HELO host name has been denied (#5.7.1)

I omitted the real domains and IP addresses for confidentiality.

I can send to everybody emails, I can receive a lot of emails, but I can't receive emails from client-x.

Someone can give me an idea of ​​what I should do.

Thanks so much.

This is probably caused by the Sophos email appliance, I have dealt with other Sophos products and they can be very restrictive. If I remember correctly, the Sophos email filter has a built in "Whitelist" which covers 99% of valid email usage, there are some clients and some servers that dont get picked up by it and will cause a rejection.

I think this may be apart of their anti-virus suite and not actually the email appliance. Are you running the sophos anti-virus as well? can you take a quick look at the sophos logs to see if it has anything about a rejection around the time the emails are being denied?

Thank you very much for your reply. I'll offer a bit more of details to be sure that we understand each other.

In my server, there are not any Sophos products. I currently use Spamassassin, and clamAV as anti-virus.

I cannot directly verify Sophos' logs, since they are in the client's server.

Thank you
