[SOLVED] Can't send mail from Guest-OS using SMTP

[DulcetAirman]

Host: Windows 7 Vbox 3.2.8
Network: Default bridged adapter (from default installation, I didn't change anything)
Guest: Mandriva Linux

On Host-OS: Both pop, imap and smtp work
on Guest-OS: imap works but not SMTP

I also Tested this on an other computer using vbox and I tried to send mails to a different SMTP-Server. So it cant be the mail servers fault.

I would love to test it myself but heres the strange thing:
I have two machines with Windows7 as hosts, but I cant use telnet to connect to the SMTP-Servers.

I thought the easiest way to debug SMTP was to use

Code: Select all

telnet <SERVERNAME> 25

But that didnt work:

Code: Select all

Verbindungsaufbau zu mail.hwis.ch...Es konnte keine Verbindung mit dem Host herg
estellt werden, auf Port 25: Verbindungsfehler

(Translation: no connection to Host, Connection error)

With this it would seem to me as if i could not send mail from the Host-OS, but I really can.

From inside the Guest-OS I get the same:

telnet: Unable to connect to remote host: Connection refused

But here I actually can't send any mail

I tried 3 different Mail-Servers. one of them even has two ports for smtp, if port 25 is blocked.
But when I set up a mail client on the Host-OS I can send Mails. I even copied the whole Account to the Guest-OS so I can be 100% sure that everything is the same but I can't send mail, I can only receive new mails via IMAP.

i also disabled the Windows 7 firewall to check if it's blocking the connection.

I'm sure I'm not the only one who would like to send mail from the Guest-OS. What can I do? How can I test it?

Stupid virus scanner did it... everything works fine now...

McAfee needs to have an exception for not preventing Virtualbox.exe to send mail. this is because it could be a mass mailer.
