Mailserver ERR_CERT_COMMON_NAME_INVALID
-
Aha, that makes sense.
Will contact my provider and get back here. -
Many thanks @Gwen-Dragon !
DNS Setup has been fixed, mx is now mail.teicher.net. which is A to the correct address.
Connecting also works now, as Vivaldi ist now showing my IMAP folders.
It's just I get no messages in the folders
Log doesnt say much to me

@Gwen-Dragon well when I use mail.teichet.net I get the ERR_CERT_COMMON_NAME_INVALID again, obviously.
So I just installed Thunderbird and it automatically recognized everything
with mail.manitu.de using current (as of 1hr ago) and immediately finds and downloaders folders and content without any SSL issues.Since the connection works with mail.manitu.de (I get the IMAP Folders)
what could be the reason I don't get messages ?Vivaldi Snapshot 3.7.2218.29 on MacOS Big Sur, no other security tools or such installed.
-
@teicher Can it be that you checked
offline?
-
@Dancer18 thanks, but no.
-
@Gwen-Dragon maybe, but they say it's okay for them, and it's also ok for Thunderbird.
Do you really think the issue of getting folders ok but not messages is caused by some more SSL/DNS issues? I'd say we already tackled that.
-
@Gwen-Dragon the teichet.net was a typo of course, thanks for pointing out.
I fixed the DNS/SSL setup -thanks to help here- so it now works without problems or disabled SSL checks in both Firefox and K9mail.
In a way I have to accept what manitu defines as their standard and works for their customers with all other mail clients. (https://www.manitu.de/service/howtos/E-Mail-Konto-Einrichtung.pdf)
If you insist I the failure to download the messages is a SSL/DNS setup issue, despite no more such errors in Vivaldi console, and despite Vivaldi can connect good enough to list the IMAP folders on the server, then I fear we won't get any farer here.
-
I think nothing is wrong with my server setup any more.
Vivaldi Mail can read folders but not messages.
This is a fresh install, current official snapshot.
I get no errors.
I can't file a bug with this non-information, unless I get some assistance how to better diagnose an opaque situation like this. -
it's 3.7.2218.29, is that the one ?
MacOS Big Sur, no special security tools.
other software (Thunderbird) can connect. (also fresh installed, no security config or exceptions were necessary) -
@Gwen-Dragon 3.7.2218.32: same behaviour.
-
okay so we were able to reproduce in a new test account in chat.
let's continue tomorrow.
-
manitu uses Dovecot, which is a common FOSS mail server, so that's definitely something to look into
-
@teicher Do you know whether I can access to a similar test account or whether I can sign up for an email like that somewhere ?
-
@Gwen-Dragon you may share the test account credentials with @gmg
-
Hello, do we have any progress here?
Can I close/delete the test mbox?
Cheers, Tom. -
Hello, so what's the status here ? Cheers Tom.
-
So the last thing we saw is that Vivaldi can connect to the mail test account I provided, and could download the IMAP folders but not their content.
Several other mail clients, including Seamonkey, Thunderbird and Mailspring can connect and download my mails just fine. All works fine using mail.manitu.net with secure SSL, and also with mail.teicher.net with unsecure SSL (which all other clients allow).
So if we're really back to certificate discussions here, this is unfortunate and I will give up.
-
@Gwen-Dragon my mail server has a valid certificate as mail.manitu.net. this is sufficient.
I provided a test account to reproduce the problem 5 weeks ago.
Did testing against it really show that the problem is caused by SSL config? -
So the SSL is good enough for every other client, and good enough to download IMAP Folders for Vivaldi, but not good enough to download messages. Makes sense. I give up. Goodbye.
-
@teicher Yes, we're getting
INBOX: Error: Error in IMAP command UID FETCH: FETCH MODSEQ can't be used with non-permanent modseqs (0.001 + 0.000 secs).This seems we're not handling the non-permanent modseq setting for dovecot setup correctly.
https://doc.dovecot.org/admin_manual/lua/We've made an issue for this VB-77952. In the meantime you could change the settings for the modseq, but we'll of course have to deal with this case.
Sorry for the delayed response. I was just hoping I'd get around to an actual fix before answering, but haven't found any simple fix for this yet.
