connection timing out

Asked by David Danforth on 2013-08-11

I frequently receive the following message:

"Error while Pinging IMAP server imap.zoho.com.
Server unexpectedly disconnected: Connection timed out"

Additionally, I receive a similar message when Evolution is 'storing' to the inbox associated with 'imap.zoho.com'.

Both messages can be dismissed with a 'dismiss' button. Evolution seems to be working properly otherwise. That is, I continue to receive the messages available on 'imap.zoho.com'.

In another post, a user with a similar, but unsolved problem was asked to query some information. I have done the same, herewith:

Lastly, Evolution is set to check for messages on 'imap.zoho.com' every 22 minutes. That said, new messages seem to appear at intervals shorter than that.

I would like to know how to eliminate the error messsages. Thank you for your help.

Last thing first: Nowadays most IMAP servers support the IDLE command and can keep up the connection, so new mail is delivered to the client instantly outside the check interval.

But your general problem seems to be related to a connection or server problem. Check your internet connection and ask the support of your mail provider if there have been technical problems lately.

If you change nameserver is it better?
Is the provider presently having issues?

Thanks

I also use Evolution as a client for mail.messagingengine.com (FastMail IMAP.) The error messages do not appear with FastMail. I have posted a message to the Zoho Mail forum regarding imap.zoho.com. I will post their reply when I receive it, but I have not heard from them as of this writing.

Try:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

Then retry

David Danforth (daviddanforth-fastmail) said : #5

david@david-ratu1-1204:~$ sudo -i
root@david-ratu1-1204:~# echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/nul
root@david-ratu1-1204:~#

That seems to have worked. I understand that this is a temporary reset to the Google Public DNS service. (I'm a noob and don't have a background in this area.)

The fact that it has worked should, then, indicated that there is a DNS problem going to imap.zoho.com, but, evidently, not to anything else.

Who would know how to fix this permanently? Zoho? My ISP?

Thanks for your help. This appears to be real progress.

You didnt need to run 'sudo -i' the file edit will happen with the command as I gave it.

If there is a DNS issue with your current DNS, you can make the change stick with:

echo "nameserver 8.8.8.8" | sudo tee -a /etc/resolvconf/resolv.conf.d/head > /dev/null

again, you DON'T need to run 'sudo -i' the tee command is ran with sudo, so has root access and therefore write access to the file.

You can reboot to test

Thanks, Andrew. Got it.
