[solved with Syno in 5 min] Setup & configure homelab smtp relay

[busch09]

Hi,
Trying to setup a smtp relay on asus merlin. tried all google threads, no avail.
found this guide:
http://smartpost.sourceforge.net/virtual_mail_server_with_xmail.htm

on the asus copied all xmail files to /opt/var/Mailroot
copied xmail to /opt/var/etc/inti.d

start the server with /bin ./xmail start, check with

telnet 127.0.0.1 25

create user
CtrlClnt -s localhost -u admin -p password useradd domain username password U
CtrlClnt -s 192.168.1.1 -u admin -p password useradd home.lan username userpassword U
Command line:
./sendmail -fuser@home.lan user@home.lan < msg.txt

email client:
pop/smtp point to router: 192.168.1.1
pop/smtp user: user@home.lan / pw in plain text (need to add domain to username)

for SMTP Relay (trying to get it top work with postmarkapp.com (9k free emails/month):
vi smtpfwd.tab
"*"[Tab]"smtp.postmarkapp.com"
then in /userauth/smtp
mkdir smtp.postmarkapp.com
vi smtp.postmarkapp.com
"login"[tab]"postmarkuser"[tab]"postmarkpw"

I can now send email internally.
I havent figured out yet how to get xmail to fwd an email to the internet smtp....

I'm surprised you managed to get it to compile.

So after 3 weeks of trying to decipher the xmail manual and the scattered forums posts I gave up on xmail.
I only want an smtp server to send emails locally from backup servers, esxi, etc.

I found https://www.dynu.com/Resources/Tuto...p-Synology-MailPlus-with-your-own-domain-name
Costs $10 a year and took me 5 min to setup on synology and works with admin@home.lan within my net as well as to anyone external.

cheers
