My Postfix server was working fine until last days but now, I can't receive emails from outside (I mean with an email of different domain name like gmail for example). I must make notice that I can send email from the server to gmail. From what I have seen, I think that issue may be my iptables rules : # iptables -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt...

I have a Borland Delphi 6.0 - 7.0 [Overlay] executable (file.exe) that I want to unpack to examine the contents. This file is from an untrusted source, I believe it to be some type of virus. Currently I have downloaded PEiD to identify the exe file as written in Borland Delphi 6.0 - 7.0. I have downloaded Sandboxie and I was plaing on ruing PEiD unpacking tool whilst in the sandbox. PEiD states that if I choose to unpack the Delphi file that it will execute the file, obviously I don't want this to happen. If I am using PEiD in Sandboxie will it be safe to execute this possible virus, specifically: If the virus executes will any files be restricted within the sandbox? Can the virus alter any...

I have 2 VPN and sometimes I should switch them very often. I decided to create .bat file which could coect to desired VPN with credentials set in this file. So I create .bat file with following code: vpncli.exe -s < 1.txt Where 1.txt contains credentials of VPN #1 which has trusted cerficate. here's what 1.txt contains: coect <vpn1.some.host> 1 <password> Where 1 goes for GROUP with number 1. The second VPN is untrusted and I have this prompt awaring me what VPN is untrusted. I used similar code for .bat file: vpncli.exe -s < 2.txt And following data in 2.txt: coect <vpn2.some.host> y <GROUP> <LOGIN> <PASSWORD> ("y" goes for accepting un...

Not a single advice i have came across helped me so far, you are my only hope guys. I registered a free certificate from startssl, and tried to install it on my postfix server. OpenSSL confirms that my private key matches the certificate, unencrypted key is chowned by Postfix user, and all other files are loading pretty well. However, whenever I either send mail, receive mail, or coect through telnet i get message in logs saying caot get RSA private key from file /etc/postfi/ssl/mydomain.key.unencr I am all out of ideas. Postfix conf: smtpd_tls_cert_file=/etc/postfix/ssl/mydomain.net.crt smtpd_tls_CAfile=/etc/postfix/ssl/root.crt smtpd_tls_key_file=/etc/postix/ssl/mydomain.net.key.unenc...
