Having been accomodating about it in the past, the technical geniuses at Comcast have permanently blocked port 25, separating me (at my home office) from my employer's e-mail server. What can be done on the server side to keep Postfix listening on 25 _and_ accept my connections on some other port? Is there a Postfix solution? iptables maybe? Miark

My wife's office server was compromised today. It appears they ssh'ed in through account pcguest which was set up for Samba. (I don't remember setting up that account, but maybe I did.) At any rate, I found a bazillion "ftp_scanner" processes running. A killall finished them off quickly, I nuked the pcguest account, and switched ssh to a different port (which I normally do

Hello everyone, Occasionally I get emails which have a subject header of "Rejected posting to Blah", from a listserv I am on. Without going into a 10 page diatribe of why, I'd like to reject these automatically, sending them to /dev/null. I used to run Sendmail and that was pretty easy to do. How can I do this under Postfix under CentOS 5.3? Any help is appreciated. Thanks!

I have a webpage feedback form that uses a Perl script to send e-mails with "| /usr/sbin/sendmail -t". It works just fine, but SELinux is complaining about it: SELinux is preventing /usr/sbin/postdrop (postfix_postdrop_t) "getattr" to pipe:[41117] (httpd_t) I'm a SELinux newb so I don't know what (if anything) to do about it. Suggestions? Miark

Using Postfix with Virtual Users/Virtual Domains, I have configured it with a wild card entry; i.e., "*.mydomain.com" This works fine in Postfix; however, using Dovecot for delivery is causing the message to bounce since Dovecot does not have an entry in the "user passwd" or "userdb" file. I want to store the catch-all addresses in a separate mailbox. Can I use sieve

I was wondering if anyone was aware of a method for mounting virtual CD devices with CD image files. I keep images (.CUE/.BIN pairs) of my CD collection on a NAS appliance tucked away in my closet. I'd like to write a script to mount each one, create ID tags, rip the tracks, then move along to the next one. I figure with a quad core opteron, it should be able to crank through them in a

Hi there, Moving this request for info over from an R-HPC-SIG list thread as the issue is less HPC than something that has bitten me as a result of trying to install HPC (read CUDA) R packages.

Hi all, I am trying to block all IP addresses from Africa due to a high rate of fraudulent orders coming from them. I have some found some websites that can generate a range of IP addresses. However, you would have to enter the ranges by country. I can use those perhaps but that would mean I would have to get the ranges for each country one by one. Has anyone here a list of addresses from
