Hi all!
I'm fearing my qmail is acting as an open relay, as my queue is getting increasingly full of e-mail qmail is now trying to send to several hosts. I've been observing this problem for weeks and it's worsening as time passes. My /etc/tcprules.d/qmail-smtp contains
| Code: |
127.0.0.1:allow,RELAYCLIENT="",RBLSMTPD=""
# This is my static IP
81.174.16.228:allow,RELAYCLIENT="",RBLSMTPD=""
:allow

(plus a ton of commented out lines of course) and is correctly compiled. Checking /var/qmail/control/conf-common, it seems qmail is correctly using that file.
Can it be those e-mails are only bounces for spam my local domains? They don't seem like that, as there are several messages qmail is trying to send to different users of a same domain.
Thanks a lot, Michele.
EDIT: after further reasearch in qmail logs I found out these are bounces to spam messages to local domains, as I suspected. However, they really tend to be a lot. I guess I'll need to use greylisting or some other spam filtering solution to limit this. |
