Claws-mail not sending

[ordep]

I can't send mail any more with Claws-mail. I get:

* Account 'ISPX': Connecting to SMTP server: smtp.serverbro.net:25...
*** smtp.serverbro.net:25: unknown host.
*** Error occurred while sending the message.

If I recall right that happened after an upgrade.

How to resolve?

[gerald_clark]

After an upgrade of what?
Sounds like your router or nameserver settings are incorrect.
To resolve it, fix the network.

Is that host supposed to be on your LAN or on internet?

[gerald_clark]

I can ping it from here, so internet.

[tinypoodle]

That's rather interesting, I was unable to resolve host ( including trying google DNS 8.8.8.8 ), nor could I find a whois entry, nor anything with a quick web search.

[ordep]

Upgrade of what? Guess a new version, can't recall only know it worked before.

I am sorry the server is not serverbro, it should read smartbro.net.

I can ping smartbro.net as well as smtp.smartbro.net.

I have  not changed my settings for for the network or in claws-mail and they are the same as
on my distro on the hard drive.

No TC version, no CLAWSMAIL version reported

[bmarkus]

Try with telnet. There are no SMTP server at smtp.smartbro.net:25 or smartbro.net:25 Not a TC nor clawasmail issue, ISP service is dead.

[ordep]

No TC version, no CLAWSMAIL version reported

TC 5.2, Claws-mail-3.9.3 

Sorry

[ordep]

What do I do with this then?

Code: [Select]

telnet 121.1.3.194 25
220 SMTP ESMTP mailer.
Connection closed by foreign host


[bmarkus]

Use IP address in clawsmail server setup if you still have DNS lookup issue in your system. But you are not showing a telnet example with domain name. Once again, it has nothing to do with clawsmail.

[tinypoodle]

What do I do with this then?

Code: [Select]

telnet 121.1.3.194 25
220 SMTP ESMTP mailer.
Connection closed by foreign host


Code: [Select]

telnet: can't connect to remote host (121.1.3.194): Connection timed out

Perhaps intermittent issue?

Have you tried with a different mail client to compare?

[ordep]

I have no other mail client.

Now somebody suggested from a distro where I have recently the same problem
to place 8.8.8.8 in /etc/resolv.conf.

Booted into TCL did that and the mail goes out with claws-mail. 

May be that will tell someone what then could be a permanent solution.

[gerald_clark]

The permanent solution is to fix your DNS.
If you are using DHCP, fix your server.
If you are using static IP addressing, you must configure /etc/resolv and make sure to add etc/resolv.conf to your backup
