Can't send emails

I’m LOST, littery…

For the past week I have been trying to setup mail with no luck, I can’t send emails but I can receive.

DNS… Configured
SMTP ports… not blocked
IP Address… not blocked

I have also read all posts from users who face same issue but didn’t help!

So far,
Mail log from CP says “Rejected RCPT: relay not permitted” and the email stuck in queue

Exim4 log
SMTP timeout after initial connection: Connection timed out

Sounds like outgoing smtp is blocked, check if you can reach the target server using telnet mail.domain.tld

I can telnet the server on port 465 and 587 only, port 25 is not connecting… however port 25 is opened!

Such services try incoming ports. It could be blocked at provider level for outgoing traffic…

Can I use 465 or 587 as default port.

Also when I try to add the email in Outlook it says IMAP a secure connection to the server cannot be established. And when I checked I got certificate warning however both web and mail got green check for SSL.

Use instead…

If you want to use 465 or 587 use a smtp relay service instead. AWS Sendmail or are cheap and/or free

I’m using as IMAP and SMTP but when I choose SSL/TLS for incoming server (IMAP) I got the above error and the only way to pass it is to choose “None”, but in any case I’m still not able to send emails!

What port are you using?

When your ISP is blocking outgoing emails on port 25, you can send emails to your hestia server, but your hestia server can’t relay your message to for example gmail → timeout…

I use Outlook IMAP/SMTP 143/587 and email stuck in queue in Hestia Server

As written, your vps provider is blocking outgoing port 25, ask them to unblock it.

Ok, thank you for support


Do you know why I’m getting a certificate warning for outgoing emails when I try to add my email in Outlook IMAP/SMTP 143/587 TLS, also for IMAP when I choose TLS it didn’t connect, it has to be NONE although Let’s encrypt is applied for mail and webmail?

Looks like a local issue: The r3 lets encrypt cert got loaded properly. Check the cert chain under certification path.

The root cert there should be trusted, is your os up to date?

Windows 7 :roll_eyes:

Well, then clearly no. Update your OS to Win10/11, this is not related to hestia at all…
