In context with the title i have the following setup:
- I own a hostname, lets say: my_hostname.com
- The A record of my_hostname.com points to my home ip using dynamic dns, lets say: 50.50.50.50
- My home router forwards ports to my homeserver: 80 & 22
- the MX records of my_hostame.com point to: my_personal_hash.pamx1.hotmail.com
- Within this outlook account i have a subaccount: my_name@my_hostname.com
and this all works great, i can use my_hostname.com to ssh to my homeserver, use my own webinterface and receive mail on my_name@my_hostname.com on the servers from microsoft which always has one online.
But now the following: my homeserver generates local mail. This with the use of crontab and people trying to guess my sudo password (just people at my place so not such a big deal). This is all placed in var/mail/my_name and i'm trying to forward these mails to my_name@my_hostname.com with postfix. (i have also tried [email protected]) but it all fails to get my mail out.
I know that my mail is probably rejected because i use a home server to send mail but how do i get around this.
This is my /etc/postfix/main.cf file:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no

In virtual-regexp is a forward to one of both tried mail addresses. after sending a test mail with "mail send" to my_name@localhost, the /var/log/mail.info generates the folowing:

What major mistake am i making and how do i get my internal generated mail into my webmail?
Ok, so with some research I found my answer.
To start, I made two mistakes. The first one was actually pretty obvious after looking everything over a few times. Just by removing:
The first problem was solved but then i was left with:
when i was forwarding to my gmail account. Also forwarding to my_name@my_domain.com generated the connection time out.
After googling around, I found in this topic that my ISP might be blocking outgoing port 25 traffic. This can be verified using:
if it does not generate Connected to aspmx.l.google.com but a timeout after half a minute or so than your ISP is blocking your outgoing traffic. {don't forget installing telnet before using it ;) }.
And this was my second problem. Luckily I broke my neck less hard by solving this one.
By redirecting through a secure connection using port 587 I was able to send mail. To do this I used this post and a new google account for my server. I am not going to retype the whole post so just click it and read it if it finds your interest. I also removed the virtual-regexp file and linker to be compatible.
Now I send mail from my home server through [email protected] to my_name@my_hostname.com through port 587 and it all works great!
