Investigating Multi-Recipient Email Delivery Issues on Cloudron v8.2.4

Hi @IniBudi, do you use any external relay email service? Eg. Postmark or similar?
I ask you this to better understand your conf but also because last week I sent same email to two different @gmail.com accounts and one of recipient in CC it seems it didn't received email.
But I'm not sure if is similar to your case.

I'd like to confirm that the problem was coming from my 3rd party email relay service. I just disabled it and using my own server without having problem at all.

@IniBudi Wich email relay are you using? I think this problem should be better addressed and understood to let have a fix...
This because we're used to use relay servers due to poor IP Vps's reputation...

@p44 In the previous setup, I used mailketing SMTP server, after using the Built-in SMTP server. I can send emails to several email addresses simultaneously.

Dear Cloudron Team,
Today, I conducted a test by sending emails simultaneously to multiple addresses such as @gmail.com, @outlook.com, and others. However, when I sent the email via Cloudron’s system, only the first email was successfully received, while the rest did not receive the message.
I then attempted a second test using “reply to all,” but the result was the same—only the first email received the message, and the others did not.
My question is: Is there an error in my server configuration, or is there a bug in Cloudron version v8.2.4? I have tried disabling IPv6 and syncing again, but the result remains unchanged. I also attempted enabling both IPv6 and IPv4 simultaneously, yet the issue persists.
Could you please advise on what steps I should take to resolve this issue?
Thank you for your attention and assistance.

Have you checked the mail event log ? It should have an entry for each outbound email.
