Corrected the problem for Thunderbird by modifying the value of the “Authentication method” option in the server settings: select “Normal password” instead of “Encrypted password”. See [https://www.swisscom.ch/en/residential/help/internet/e-mail-setup-ssl.html](https://www.swisscom.ch/en/residential/help/internet/ e-mail-setup-ssl.html)
I had the same problem with eM Client. But strange only on one of my two accounts. The hotline couldn’t help me. They wanted to pay me extra CHF 40 to configure eM Client.
I think I found the reason: changing the authentication mode to the “old fashioned” imap.bluewin.ch / Port 143 / use of SSL/TLS if available made it work again.
As said this applies only to one of my accounts and only with the program “eM Client”.
Hopefully Swisscom will fix this soon.
Thank you for your help!

Thank you so much, tried for an hour to solve this. You saved my day.
Merci beaucoup
It has been impossible to access emails for 20 days now.
My Thunderbird client was already configured with the security settings that had become mandatory. Even better, the password was previously encrypted which you have now deactivated, security-wise I don’t see how this would be any more secure.
I followed your “update” guide which is also not displayed in chrome. Indeed, if we inspect the page we see a number of JS errors, in particular DOMException errors in a Promise.
After spending considerable time following your guides and following this forum, I began to telnet to confirm what I suspected: Your servers are no longer responding properly.
Indeed:
- the telnet command imaps.bluewin.ch 993 opens a connection, but no response from your MTA.
- the telnet command imaps.bluewin.ch 143 returns most of the time “connection refused”, occasionally “* BYE cannot connect to IMAP sever (ip), connect error 10060” or error 10061
- the telnet pops.bluewin.ch 995 command systematically returns impossible to open a connection to the host, (…) failure during connection.
- I tried to connect with three different clients and two different internet connections
I couldn’t find any support number, I read here that you charge 40.- to intervene. The problem is clearly with you, I refuse to pay anything.
Please give me, in response to my post, a free contact option, I have spent a lot of time debugging *your* infrastructure for free while I pay for your service.
@Retteidio51 First of all Good evening
I will disappoint you, third party applications like Thunderbird Outlook etc. is not the responsibility of Swisscom so if you have a problem you must resolve it yourself or consult a private IT specialist or the Swisscom paid service.
Swisscom provides a basic free service through their hotline for their own programs and materials.
For your information, you can always check your emails through the webmail page on the bluewin website.
On the thread of this post it seems to me that the solution has been found. As for the deactivated encrypted password, this is normal since the email is encrypted with your identification and password.

Hello @Doremi,
Thank you for your response which unfortunately is not useful to me.
I’m sorry, I didn’t greet you because we are on a community forum, on this topic almost no one has done so. At the same time, I didn’t speak to you or raise my voice.
None of the solutions proposed here work.
Telnet commands are very low-level commands used to validate whether a server is responding or not. Different clients on different computers and internet connections can eliminate a cause specific to these systems.
An MTA is a mail transfer agent, it is software like postfix or dovecot which is installed on the servers and allows the actual sending and reception of emails.
I confirm that webmail works well, it’s the first thing I tested to validate the password. But for reasons that I do not wish to explain here in public, this is not a solution for my case.
I am an EPF Ing Dipl in IT, I have configured several MTAs myself. I don’t need an IT specialist, I just want bluewin to fix these servers because I can’t do it. The clients are not the responsibility of swisscom but the servers are!
I thank you and send you my best regards.
PS: it was me who wrote the previous message (@Retteidio51) from the PC and therefore my mother’s account
Hello Vauziopien75,
Please let us know about the problem. As stated above we ask our users with private clients to use SSL encryption and to no longer use the obsolete CRAM-MD5 protocol. During the migration phase some private email programs reacted with an error message.
This phase of the migration is now complete. Can you try again with the desired settings and let us know the result?
Thank you very much and Cordialement

Hello @Vauziopien75
A detail strikes me when rereading the last message.
I confirm that the webmail works well, it is the first thing I tested to validate the password. But for reasons that I do not wish to explain here in public, this is not a solution for my case.
The password used for webmail is that of the Swisscom login. If you access the mail server directly with an application, it is the password of the mailbox that must be used, it is different. It cannot be recovered, but can be reset through the customer area.

Hello @ThomM,
Thanks for your response. I was able to test today without success at first.
The following message was correct, the email password was changed from the customer area and I was able to access the email with the parameters mentioned.
Yours sincerely

Good morning,
I just had this problem with several accounts on Bluewin.ch with Thunderbird under Windows 10.
After multiple searches, changing password, checking settings, nothing to do. Note that the requested changes were made upon receipt of the message from Swisscom.
On Android, the bluemail app, with the same settings, worked without problem.
When trying to install the same app on Windows (Bluemail) and configure one of the problematic accounts, I came across the SSL/TLS option, but also SSL/TLS (check certificate). Using this option with the bluemail app it works.
On Thunderbird this option does not exist. So I go to the Thunderbird settings, “advanced” tabs then I click on “manage certificate”. In the window that appears, I find a “Swisscom Root CA 2” certificate. I decide to delete it and try my luck again, miracle, it works!
You never know, maybe this will help someone else.
