@hummlbach Thanks for the help and for the email attachment, which I successfully transferred to the phone and installed. Unfortunately, the effect is the same - still no new messages since November 21st when I set up the account on the phone.

I have spotted something that may be of interest in dekkod.log: in the log file the connection security is shown as STARTTLS, whereas it should be SSL/TLS. I don't know enough about such things to be able to understand the difference / possible significance.

@hummlbach Please see my earlier comments above. By a somewhat convoluted method I have the dekkod.log file below. It's a bit long, but very repetitive.

@The_Cougar_Kid
i have solved to second problem using utext instead of tedit. I can now see dekkod.log in logviewer. I have now got to work out how to send it to you! The last two entries on the log read:

IMAP : "2" RECV: a004 BAD invalid search command syntax, invalid search criteria syntax

Messaging : Push email connection could not be established. Reattempting to establish in 480 seconds

(repeated many times)

@The_Cougar_Kid
First problem is that ~/.cache/upstart/application-click-dekko2.dekkoproject_dekko_*.log doesn't seem to exist.... I looked for it using file manager and also using logviewer.
Second problem is that I can't work out how to edit ~/.config/dekko2.dekkoproject/dekkod.conf in the way you have advised, though I can at least find that file. I have installed tedit if that helps.

@hummlbach said in Problems with incoming emails in Dekko2:

We need to have a look at the log files... The Log of the frontend is found in ~/.cache/upstart/application-click-dekko2.dekkoproject_dekko_*.log. The logviewer can be a nice help here. I'm afraid we also need the log of the background process. Thats a bit trickier. First we need to enable logging, by setting Enabled=1 in the [StdStreamLog] section of the config file ~/.config/dekko2.dekkoproject/dekkod.conf. After restarting the phone (or only dekkod by issuing the command restart dekkod), you'll find the log as dekkod.log in ~/.cache/upstart/.

I'll have a go - thanks.

Re: Dekko2 Developer Community Thread

Hi
I have recently installed UT on a Nexus 5, and, because it is so vital for me to be able to check emails on it when away from home, I installed Dekko2. It was great to see more or less the same look and feel that I had enjoyed previously with my earlier bq Aquarus 4.5 Ubuntu Edition. I had no problems installing Dekko2, nor setting up an IMAP email account, I could send messages, reply to messages, delete messages - though 'delete' is a bit 'flaky'. However, though my 'as it was at the time of setting up the email account' inbox (and, indeed, sent mail box) were available on the phone, I have been totally unable to receive any subsequent new messages on the phone.

Following advice read elsewhere on this forum I have tried deleting the email account / cleaning .cache and .config / then recreating the email account, uninstalling / reinstalling Dekko2, rebooting, starting / stopping dekkod, several times, in several combinations, but always with the same effect: i.e., the complete inbox as at the moment of account (re)set-up reappears, along with the complete sent folder. But subsequently, though messages that I send from the phone get added to Sent mail, nothing new comes into the inbox.

I use a Ubuntu desktop and I am a passionate enthusiast about UT, and Dekko, though I have limited technical skills and knowledge.

Can anyone help, please? Not being able to check new emails on the phone is a show-stopper for me.

I have tried the 'sledge-hammer' approach: delete all email accounts, uninstall Dekko2, clear residual Dekko files in .cache and in .config, reboot, reinstall, re-set up one IMAP account, and ...... same situation! [This is all on a brand-new (one week ago) installation of UT on a Nexus 5.]

PS Whilst rummaging through the file store I spotted folders relating to Evolution. Is this just some random hangover from Canonical's original ambitions, or is some version of Evolution available on UT?

Thanks for those thoughts. I have tried close / restart Dekko2, and rebooting. No difference. I thought that I set up the email address as IMAP but I'll check. My email server can be accessed as either IMAP or POP3, but I thought I selected IMAP.

I note there are alternatives to Dekko2 in the Openstore. Are any of those reliable.

My Storyboard: I purchased a BQ Aquarius 4.5 back in 2015 and I had been using it, running Canonical's original UT, as my daily / only phone up to about 2 months ago, when I accidentally physically destroyed it. I absolutely loved it so today I was delighted when I finally laid hands on a new boxed Nexus 5 and I have installed UBports UT on it. I am basically very pleased, but I have two serious problems with Dekko2 that I didn't have with the original Dekko.

1 When I set up my primary email account as an IMAP account, all my existing inbox / sent messages appeared as I would have hoped. I am able to send emails quite happily - except Dekko2 does not connect to my contacts, nor does it seem to enable its own private address book - as was the case with original Dekko. Thus to start a fresh email thread I have to retype all 'to' email addresses, which is crazy! Am I doing something wrong?

2 Even more worryingly, though all my existing messages flooded in when I set up the email account, I have not been able to receive any subsequent messages. Am I doing something wrong?

Thanks for any help
