IMAP Folders showing incorrect on 1und1/Ionos Accounts

[Roland Meier]

Hello,

your switch works well, but on my 1und1 Account the Archive Folder Structure is showing each separate. The folder structure comes from Thunderbird and works here also on Webmailer, see Screenshot 1.

But in Roundcube it shows each folder separate which results in a long list, see Screenshot 2.

I don´t know the limiter, I think Archives/2014/2014-01

Would be great if this works in near future.

Hello,

same issue on current 1.4rc2

[Boris Gulay]

Looks like it’s an issue in Roundcube not plugin

[Roland Meier]

Hello Boris,

great to read from you.
Roundcube has an option for in defaults.inc.php for this:

// If you know your imap's folder delimiter, you can specify it here.
// Otherwise it will be determined automatically
$config['imap_delimiter'] = null;

This works for all the accounts directly hosted on same machine.

But only the external Ionos shows since years this error, also on the current stable 1.3.10 as 1.4RC2

An older Plugin had a separate delimiter field, the new one not.

I hoped this is a topic from the plugin, as the Roundcube Github closed also my topic according this with… “Thing of Plugin developer”.

Happy that the plugin works also on new Roundcube, but if this gets corrected it would be great.

Hello,

when I set the the imap_delimiter to '/' the 1und1/Ionos Account Folder works. But then the others wont work.

I have to set generally the ‘.' or NULL value and only for mails from 1und1 on '/’

The old plugin version had such a delimiter field… The new not?

[Roland Meier]

Hello again,

the problem acc. imap.log is that in a single session the delimiter is detected based from the login mail:

S: * NAMESPACE (("" ".")) NIL NIL

When the switch to the 1und1 account comes the namespace is not redetected, here I need a “/” but from before its a “.” so the orders are not listed correctly.

So for my understanding, its not a thing of roundcube. The ident_switch have to redetect on change of mail account.

Can you confirm this?

[Roland Meier]

Small hint from Roundcube author:

A hint for the plugin author. Imap delimiter and other capabilities are stored in session
storage. So, the session need to be cleared when switching servers.

[Boris Gulay]

So, looks like I have to add this option (IMAP delimiter) for remote accounts. Right?

[Roland Meier]

Yes would be great, wen the delimiter switch on account change to corresponding delimiter.

[Roland Meier]

Just a Feedback, are you planning to do this in the next time?

[Boris Gulay]

Hi. I will do it this month.

[Roland Meier]

Great

[Boris Gulay]

Add delimiter to account setup. Closes #50

Hello,

I tried your new files like follows:

1. I downloaded the new package
2. I uploaded on a fresh ident_switch Plugin folder
3. I added the additional column into table

There is a new field (without translation) in which I can insert a . or a /

My 1und1 need a / its saved but the same view as before.

I tried also to make a . without success. Also on other accounts which uses normall . and I insert / thats make no difference???

[Boris Gulay]

Will check tomorrow.

By the way, what language of UI do you have?

[Roland Meier]

I use german.

[Roland Meier]

OH… Sending Mails from SMTP no working since last update, but only on the 1und1 account… This was working before???
Changes regarding this?

[Boris Gulay]

Hi.

Only fix for another issue. But it should’t brake anything.

What in the logs?

[Roland Meier]

The version before worked with 1und1 SMTP Port 465. But not with current version.

But with the Port 587 it works again???

[Dennis U.]

I had the same issue that 465 did not work, but 587 does the trick (server is smtp.1blu.de). The port 465 still works for Thunderbird (Desktop) and K-9 (Android).
If I run tcpdump, I can see the 3-Way-Handshake, but nothing more happens until the Connection Teardown via TCP FIN. During this time, the web interface became unresponsible until the connection timeout.

However, TCP 587 as workaround is enough for me.

[Boris Gulay]

Port 465 is for SSL. 587 usually use TLS.

SSL is not supported by plugin because it was compromised years ago.

[Dennis U.]

@Boris Gulay Yes, SSL is breached, TLS is its progression or replacement (actually SSL 3.0 is TLS 1.0, therefore SSL and TLS are sometimes used as synonyms).

But the differences between port 465 and 587 is that port 587 is basically unencrypted and can be upgraded to an encrypted connection by calling STARTTLS. Since the first communications are unencrypted, man in the middle attacker can remove the wish to upgrade to TLS (I guess it is called STRIPTLS).

Port 456 is SSL/TLS encrypted generally, similar to HTTPS. Therefore 456 is called SMTPS and should be used in favour of STARTTLS.

I´m back to Tag 4.1 again, because I had also with my other accounts and port 465 big problems. With 4.1 it runs. With 4.2 also the imag-delimiter is not working as expected.
