Hi everyone, I have been using mailcow selfhosted for about 3 years. So far everything has worked without problems, only after the last update on July 13th. I get "no mailbox selected" when I log into SOGo. Before that, the last time was on July 6th. `update.sh` executed. [Unfortunately, other discussions didn't work for me.](https://community.mailcow.email/d/23-mailcow-on-aws-no-mailbox-selected) I hope you can help me here. If someone needs further information / logs, please let me know.

Hi, Please try this (run from within the mailcow folder): ``` source mailcow.conf MAILCOW_BRIDGE=$(docker-compose config | grep -i com.docker.network.bridge.name | cut -d':' -f2) while read NAT_ID; do iptables -t nat -D POSTROUTING $NAT_ID done <

SOGo "no mailbox selected"

diekuh

The output of ip6tables -L -vn -t nat would be great, too. 🙂

chesseling

Hi diekuh!
Thank you for the fast answer.
ip6tables is attached:

When I execute your commands the following error message appears: Usage: grep [OPTION]... PATTERN [FILE]....
The variable $IPV4_NETWORK was empty, according to mailcow.conf it is 172.22.1.
So I executed the commands one after the other and lo and behold: it works, SOGo finds the mailboxes again!

Only the synchronization with the active sync devices like smartphone does not work yet, do you have an idea or tip here? In the log I find nothing noticeable, except for the errors with current source cannot synchronize defaults:

Oh, yes, I forget the source mailcow.conf part in front of the command, sorry.

Try to login as mailbox user and reset the EAS cache.

chesseling

I deleted the EAS cache, and after 1-2 hours the smartphones started to synchronize the emails.
Thank you so much! diekuh

jtdoank

chesseling
can you help inform me how to delete EAS cache,

i just restore from mailcow backup to other server and now i am facing no mailbox selected 😓

thanks

diekuh

Great to hear that! 🙂

chesseling

Hi @diekuh, I hope you can help me with another problem related to this.
After I have executed your commands (I have to execute them every time the server is restarted), other docker containers from other networks (like 172.19.x.y) on the same host cannot send emails to the email server. $HOSTNAME is used as smtp host.

SMTP Error: Could not connect to SMTP host.
It looks like after your commands above, no connection can be made from other docker networks.

chesseling

Alright, now everything works!

certdumper did not work propertly, so no certificates were copied from traefik and the certificate had expired a few days ago.

chesseling

jtdoank Log in at Mailcow as an mailbox user (not at SOGo), under Mailbox -> Settings click on Reset Active Sync Device Cache -> Reset Now.

But that doesn’t sound like the problem that the EAS cache could solve. Are the accounts with the mailboxes still in Mailcow? You only see the error in SOGo?

jtdoank

chesseling

Hi so sorry late reply,
already reset but still no result

Yes, the account still on the mailcow and even the message also still count as it is
also
Yes the error is only on SOGo

but its seems the dovecot problem
did anyone ever facing this problem?

jtdoank

anyone?
