Quote from: SKaero on Today at 01:08:26 AMSo that confirms that the issue is the "UPDATE 1" that the mail server is sending Roundcube. Looking at the script your running I think the "UPDATE 1" is the output of the psql command, try adding --quiet to that command to suppress the output if that doesn't work try piping the output to /dev/null

Thank you very much, it worked. Logon script change to:
psql postgresql://$DBUSER:$DBPASS@$HOST/$DB --command="$QUERY" >/dev/null

Quote from: SKaero on Today at 12:29:55 AMI don't think my request was clear, I would like to see the log from a working login and and failed login. Looking at what was posted I don't know what the "UPDATE 1" is there for and my guess is that is what is causing the issue but I would like to confirm with a comparison to a successful login.

ok. log for succesfull login

Look first code in my message.

Enable imap_debug in the Roundcube config and then look at the log to see what the mail server is returning to Roundcube.

Use: roundcube 1.6.13 + php 8.3.6, Dovecot 2.4.2. Users authenticated use CRAM-MD5 encrypted passwords. (for plain passwords - all ok). dovecot running script after succesfull user login, roundcube cann't login. if disable postlogin procedure in dovecot - roundcube sucessfull logon.

Thuderbird worked correctly without errors.

Please help.

We just published the fourth release candidate for the next major version 1.7 of Roundcube webmail.

This release fixes two minor issues, it's mostly published to fix a file permission problem in the previous release v1.7-rc3.

The changes are:

• Ensure correct file permissions when building a release.
• Installer: Fix broken link to download the created configuration file (#10092)

The tarballs can be downloaded from roundcube.net/download.

Or directly from the release page at github.com.

We believe it is production ready, but we recommend to test it on a separate environment.

Migrate existing configs with either the installto.sh or the update.sh scripts.

And don't forget to backup your data before installing it!

Hi JohnDoh!

Quote from: JohnDoh on February 12, 2026, 09:00:13 AMsymfony/polyfill-php85

You were right, thanks for the hint! I had symfony/polyfill-php80 installed which might have worked until beta2 of Roundcube. The ReadMe of polyfill-php85 states the new functions array_first and array_last (amon others). I've upgraded it to symfony/polyfill-php85 and now it runs again.

I've seen many some to domains with Roundcube and others without, I do think they pickup domains that are on cPanel more often though since Roundcube is the default webmail for cPanel.
