Cloudron Forum

I enabled Dynamic DNS in Cloudron. Then, I turned off the VPS, deleted its IP's (ipv4 and ipv6) and reassigned new ones. Manually updated DNS record of my. to point to the new domain and it came up in 2 mins. Resynced DNS and it looks like the SMTP issue is fixed.

Ah the Cloudron is on version 7.5.2 which had a bug here. This is fixed with v8.0 already

@AartJansen '+' is the default qualifier. So, it is redundant in +a:my.friendwholesale.co.nz . You can remove it.

@girish Perfect, that solved it. Thanks!

@JUVOJustin said in Send email with brevo relay:

I have a sender configured for my-domain.com, while the server has cloudron01.my-domain.com . How can i solve this?

Just to double check - on Cloudron, the relay system requires "domain" level relaying . Meaning, it requires a relay that can send with FROM address like <anything>@domain.com , as opposed to specific-address@domain.com . Can you confirm this?

I think the easiest would be to allow changing the "From" domain in case a relay is used, since the sending domain will most likely be handled by the relay provider.

You can change the From Email address of an app in the Email section of the app - https://docs.cloudron.io/apps/#mail-from-address . If you want my-domain.com , then add this in the Domains view. It will then appear in the dropdown of the Email domain selector as well. Then, Email -> my-domain.com -> Configure Outbound as brevo.

@cylon usually, you can request your VPS provider to open that port and they might if they trust to now spam 🙂

Alternative is to setup a relay - https://docs.cloudron.io/email/#relay-outbound-mails

If you want to receive email, you have unblock incoming port 25.

If you just want to send emails, then use a relay as @jdaviescoates suggested.

I created a new SMTP user and that worked like a charm. Not sure why adding an access key for the existing cloudron SMTP user doesn't work.
Either way, important thing is that it is working now.
You may mark this thread as resolved. Thanks!

@mhgcic we have a pretty tight set of principles we follow. Doesn't mean stuff doesn't get through, but we take action pretty fast depending on the severity of the situation

Thanks, we will take a look.

@girish Nice. Wish Cloudron could fix all the other mistakes I make.

@umbergerba I am using iCloud as a second smtp server on my iPhone. Two things:

the server that works for me is smtp.mail.me.com You have to generate an app specific password in your iCloud settings because you probably have activated 2FA. Apple Support Doc

Hope that helps.

Best,
Sven

@girish can you just set them much lower like 20s?

@girish yes, that was the issue.

@RazielKanos said in can't send mails to gmail:

The IP you're using to send mail is not authorized to send email directly to our servers. Please use the SMTP relay at your service provider instead. Learn more at https://support.google.com/mail/?p=NotAuthorizedError f13-20020a05600c4e8d00b003c6f97b761esi8416758wmq.104 - gsmtp

Oh, I missed this. See https://support.google.com/mail/answer/10336?hl=en . Basically, google does not like your IP. Maybe they have blocked the whole IP range of your VPS provider . You have to use a relay - https://docs.cloudron.io/email/#relay-outbound-mails

@roofboard did you get this sorted out?

@girish Mailgun. It hasn't happened again (so far). BTW, the notification error listed only two out of ten domains (all using Mailgun).

To send emails from a domain not hosted on your app, configure the domain in the Email view for External SMTP and try using SMTPget for a reliable service.

@hollosch 👍 👏 🍾

We didn't get to the bottom of this but the user solved it by moving to sendgrid.

@girish Wow that worked perfectly, thank you so much! 😊
