No Nethserver email via Nextcloud Mail app

[oneitonitram (Martin)]

did anyone ever get a solution to this problem.

seems to be a persistent issue.
i am facing similar issues.

whati want to understand is.

is everyone facing a problem using local ldap, or remote bind on the mail server

Please try the following to set ACLs for public folder and then try again to configure Nextcloud Mail.

doveadm acl set -A Public authenticated lookup read

I found another thread about the Nextcloud error and I think @thorsten is right here:

Nextcloud mail app config error

Hi, I am not shure, but for my feeling, it has something to do with this here: -> Maybe the forbidden ACL leads to the same error, however with a larger impact on the nextcloud client. I am more and more convinced that may be solved on the Dovecot level. Maybe it could be worth giving a try to alter devecot ACL. Best regards Thorsten

[oneitonitram (Martin)]

this fixes the problem.
thanks @mrmarkuz well appreceated.

i am now able to configure emails via manual.
Autodetect still does not work.
also facing similar challenges with outlook, cant configure emails

[mrmarkuz (Markus Neuberger)]

For Outlook autoconfig/autodetect I can recommend the automx module by @danb35, it may work for nextcloud mail too (don’t know).

https://wiki.nethserver.org/doku.php?id=email_autoconfig_module

Other things to check for working autodetect:

• IMAPS 993 and SMTP 587 port open to the public
• Configure correct helo host

doveadm acl set -A Public authenticated lookup read

OP here! I still haven’t got NextCloud Mail working so good to hear about a solution. I disabled NextCloud Mail earlier so to try the solution I went to enable it (Mail 1.1.3). But…

• This app cannot be installed because the following dependencies are not fulfilled:
• Server version 17 or lower is required.

My NextCloud for NethServer is 1.9.0.

I want to be sure everything correct is in place before I try the solution!

[mrmarkuz (Markus Neuberger)]

@DavidG

• This app cannot be installed because the following dependencies are not fulfilled:
• Server version 17 or lower is required.

Where do you see these warnings?

Mail app is downloadable for latest Nextcloud 18:

https://apps.nextcloud.com/apps/mail

@DavidG

My NextCloud for NethServer is 1.9.0.

nethserver-nextcloud-1.9.0-1 including Nextcloud version 18.0.1 with mail 1.1.3 working here.

[DavidG (David Gordon)]

@mrmarkuz

Where do you see these warnings?

When I went to the NextCloud apps to reinstall Mail. However, I tried again and installed no problem. Even better I used the command given above and I now have email on NextCloud.

Thanks to everyone!

Yippiihahhhaaa … das klalalalalappt … Danke schön. Mail in Nextcloud funktioniert nun.

Edit - Translation
Yippiihahhhaaa … that wowowowoworks… Thanky you. Mail in Nextcloud up and running

[schweidj (Joachim Schweidler)]

Great. This solution fixes the problem for me too.

Thank you very much @mrmarkuz

Nextclould email has stopped again
I tried applying the command again but no luck. My mail is working fine elsewhere including via RoundCube. Meanwhile over in my Nextclould logs I see email errors

Fatal mail OCA\Mail\Exception\ServiceException: IMAP errorError connecting to mail server.

Maybe it really is time to give up on Nextcloud mail. How is everyone else’s running?

[m.traeumner (Michael Träumner)]

@mrmarkuz Do you have an idea?

[DavidG (David Gordon)]

I’m not going to worry about this, I’ve removed the email from Nextcloud. I don’t really need it. Nice to have but too much trouble.

@mrmarkuz

doveadm acl set -A Public authenticated lookup read

This resolved the issue for me.

1 NethServer (email host) installed and I applied this ACL and it resolved my ability to have a secondary NethServer (nextcloud) login and function properly.

[DavidG (David Gordon)]

Yes, that’s the code I used a few weeks ago to get NC mail working. I did try again but it didn’t work this time. As I say, I can live without NC mail. I have Roundcube.

[mmaridev (Marco Marinello)]

Thank you. This command worked for me too. Just a question: what does this acl mean? Does it have any security issue? May I allow it on a single IP?

Thanks

@mrmarkuz

The doveadm command just sets an additional read right for the Public folder. I don’t think that any client has a problem with that.

doveadm acl set -A Public authenticated lookup should reset the Public folder permissions as they were before.

Wiki has been closed

Access public junk folder from roundcube

The permissions are set in dovecot, the IMAP server. You need to use doveadm acl on command line. Just to give some ideas: Get permissions for Junk folder: doveadm acl get -A Public/Junk Set permissions for authenticated users to allow read of Junk folder: doveadm acl set -A Public/Junk authenticated lookup read Delete permissions for authenticated users on Junk folder: doveadm acl delete -A Public/Junk authenticated

I cant get it to work… I would like to get a log of it, where can I find it?

[mrmarkuz (Markus Neuberger)]

Nextcloud logs are in /var/lib/nethserver/nextcloud/nextcloud.log.

[fausp (fpausp)]

Thank you! Just got this:

Any suggestions elsewhere to debug?

Maybe telnet to imap port to check if you get the “NOPERM permission denied” error:

Nextcloud mail app config error

I tested both on my production machine and on a freshly installed VM. Do you also get the NOPERM answer when querying the server using the STATUS command ? # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. .

Let’s check the permissions:

doveadm acl get -A Public

To set them for working nextcloud mail:

doveadm acl set -A Public authenticated lookup read
