If I watch the logs on the mail server with
sudo tail -f /var/log/mail.log | grep MY-IP-ADDRESSI can see the error when Dekko tries to connect to the server:dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=MY-IP-ADDRESSso I guess Dekko doesn't send the username to the server???
-
@mihael that would be very unusual. But the settings can be finicky at times. Please double check the mail settings in Dekko. Maybe even create a new fresh account config for the same mail account.
-
@arubislander Thank you for your input! But that is where the problem occurs: when I create the account and hit "Next" after manually entering the imap server and all details, it shows for a moment "Checking credentials" and then returns to the same screen, never proceeding further...
-
I managed to send emails from Dekko: it worked only after I defined Identities for each email account. I'm still not able to receive emails.
-
@mihael I initially had this problem with Dekko. I would see the older emails but not the newer ones.
I got it working by reinstalling the app. It will appear only as Dekko on the focal Open Store. Reboot and then try refreshing the app again without touching your connection/account settings.
-
@TakoR Thanks for the idea but no difference here...
-
Deltachat started downloading emails after a restart of the phone. This shows me the problem must be with Dekko and not with my email server. What else could I do / check? Thank you in advance for any idea!
-
@mihael if sending (SMTP) worked, but receiving (IMAP) didn't, then I am afraid it must be due to some misconfiguration of the settings for IMAP. Could you double check the port number, protocol and credentials against what your mail provider requires? Sometimes it is just a small detail. And Dekko is not very upfront with reporting errors to the user, mostly failing silently, when something is wrong in the settings.
-
@arubislander After the upgrade to focal, credentials were the same as under xenial but Dekko stopped receiving new emails - so I don't think that's the cause. I have three accounts, none of them work. IMAP or POP3, no difference. I deleted and recreated the accounts several times.
-
Maybe I could take a look into dekko's config files... I found some db files but they require a password to unlock... Does anybody have any input about these directions?

Trying to conect from my phone to the email server through openssl, I noticed that connecting to the SMTP port 465 I was getting access to the telnet terminal but the IMAP port 993 was not giving me access to the terminal. The command was:
openssl s_client -crlf -connect MY-EMAIL-SERVER:993Investigating further I noticed this error in the response:
error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small
The solution for this was: https://askubuntu.com/questions/1233186/ubuntu-20-04-how-to-set-lower-ssl-security-level/1233456#1233456 - I implemented the mods with
sudo nano /etc/ssl/openssl.cnfThen I was able to connect though openssl to port 993 but it was only a restart of the phone and deleting / redefining accounts in Dekko that it started downloading messages.
Victory! :flexed_biceps:

@mihael try imap port 995
-
@wizardi3 Sorry, I don't understand... Why? - do you need help and you want me to check if 995 works? - because for me the issue is solved, I will not change the port now unless you need me to try 995 as well.
-
@mihael No I misunderstood I thought 993 was not working. Sorry

That's exactly what I am experiencing (on Xenial). Now, if Google dropped support for insecure apps as mentioned, there is no solution, is there?
-
@gdegrez There is a solution and it's described here: https://forums.ubports.com/post/74535

I of course know this thread.
But as I mentioned there, google won't let me turn on less secure apps!
And Yahoo app password generation doesn't work.Back to square 1
-
@gdegrez Sorry, I can't help you with the gmail account - I tried to follow that solution only for testing purposes (I don't want the google account on my mobile devices) but when I tried to enable less safe apps on google it asked me for my phone number and it was there that they lost me... I don't like that so I didn't follow through... So I don't know how to do it. But if that's a google account issue, you should find more help on internet.
-
Finally got it to work with my Google & Yahoo accounts using app passwords on Xenial!
Took me a while to figure out what went wrong the first times but all is well that ends well
-
@gdegrez So what went wrong the first time and how did you fix it?
