Hello, I'm trying to send out email notifications using Native Apprise in Borgmatic found at https://github.com/borgmatic-collective/docker-borgmatic I followed the instructions by adding a hock in the config.yaml file for borgmatic as per below but I'm not receiving no emails. Do I need to make some changes within mailcow to allow for sending emails locally with apprise? Any help will be much appreciated. apprise: services: - url: mailto://mail.mydomain.com:587user=user1@mydomain.com&pass=mypswd&from=user2@domain.com label: mail start: title: ⚙️ Started body: Starting backup process. finish: title: ✅ SUCCESS #body: Backups successfully made. body: $(cat /tmp/backup_run.log) fail: title: ❌ FAILED body: Your backups have failed.

Tried different syntaxes but still no luck to send notifications. (https://github.com/caronc/apprise/wiki/Notify_email#using-custom-servers-syntax)

esackbauer Postfix logs? It seems like you are missing STARTTLS. The password is from user1 or user2?

I’m not receiving any postfix logs. the password is for user1 (karl)

I modifed the apprise hook to get logs when creating a backup manually. I’m receiving a time out.

kiekar the password is for user1 (karl)

It seems your mailto(s) syntax is completely wrong… Still no STARTTLS…

kiekar If you’re not seeing postfix logs of apprise attempting to send the mail, then it was outright unable to connect to the server, which usually indicates some kind of configuration issue. Since the documentation recommends adding the borgmatic container to the mailcow bridge network, try setting the hostname to postfix, rather than the FQDN of the mail server.

Tried different syntaxes but still no luck to send notifications.

Try to use port 25 without any authentication then. add the sending server IP to the postscreen whitelist.

Thank for all your input but unfortuneately I’m no further ahead. Tried mailto for port 25 syntax but same results. I’m currently not using postscreen.

What is wierd for me is that I’m able to send email notification out for unattended upgrades, Veeam Backups and Mailcow backups by installing postfix as a send mail only with relayhost enabled.

Thanks for your input but still no go for email notifications. Receive time out. Below is the output when manually runing borgmatic -v 2

You’re close:

# use mailtos:// not mailto://
# use question mark ? to start arguments 
mailtos://mail.mydomain.com?user=user1@mydomain.com&pass=mypswd&from=user2@domain.com

kiekar

SnailShea try setting the hostname to postfix, rather than the FQDN of the mail server.

Not sure what you mean

caronc # ssl mode (uses different port)
mailtos://mail.mydomain.com?user=user1@mydomain.com&pass=mypswd&from=user2@domain.com&mode=ssl
if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute(‘data-s9e-livepreview-onupdate’)) {
window.hljsLoader.highlightBlocks(document.currentScript.parentNode);
}

Edit: i noticed you’re not identifying the SMTP server directly, try:
mailtos://mydomain.com?smtp=mail.mydomain.com&user=user1@mydomain.com&pass=mypswd&from=user2@domain.com

Non of the syntax modifications worked.

caronc

Connection timeout connecting to your SMTP server is the focus point of your error message. You don’t appear to have port 587 open from the server using Apprise. You could try:

# ssl mode (uses different port)
mailtos://mail.mydomain.com?user=user1@mydomain.com&pass=mypswd&from=user2@domain.com&mode=ssl

Edit: i noticed you’re not identifying the SMTP server directly, try:

mailtos://mydomain.com?smtp=mail.mydomain.com&user=user1@mydomain.com&pass=mypswd&from=user2@domain.com

kiekar mailcow-dockerized uses the “bridge” driver for docker networking, which you can imagine as a virtual switch with containers on that network plugged into it. Because of this, containers in the mailcow project should be able to communicate with one another using the host names configured in the docker-compose.yml file. If the borgmatic container cannot reach the host postfix, something is wrong with your configuration. Ultimately using postfix for the SMTP server name isn’t the best idea, as the certificate for your mail server FQDN will not match. In the short term though, this should work, barring apprise refusing to trust unverified certs (I have no experience with apprise).

My suspicion is that your network is setup in such a way that hairpin NAT isn’t working. Enabling hairpin, if it’s not already enabled, should resolve your issue. I believe that apprise is trying to find mail.yourhost.tld, sees a record for a public address, the request leaves the network, but on the way back in to contact your mail server, is not able to find the appropriate route to form a connection. This is generally resolved in your router.

Thank You for your explanation. I do not know the inner workings of Apprise, I was just following instructions from

borgmatic-collective/docker-borgmatic?tab=readme-ov-file#using-apprise-for-notifications and
caronc/apprisewiki/Notify_email#e-mail-notifications

To get nofications for errors during backups.

To my best knowlege all is working fine with Mailcow. I also do get email notifications for unattended upgrades, Veeam Backups and MailCow Backups with postfix as a send only smpt server using relayhost set.

The Mailcow Mail Server is currently behind a pfSense firewall using 1:1 NAT

kiekar Do you have the following options enabled in pfSense?

SnailShea Do you have the following options enabled in pfSense?

No, I did not.

I did now enable it but still no go for notifications.
