Out of the blue I cannot send emails anymore from my MacBook Pro. It appears the SMTPO server is offline and I cannot reconnect.

Good evening [Schofeungum29](https://community.swisscom.ch/t5/user/viewprofilepage/user-id/515153) Please check in your E-mail client that your authentification method for the smtp server is set to "password" and not "CRAM-MD5" (or something else): SMTP: smtpauths.bluewin.ch (Port 465) Authentication method: password, normal or SPA deactivated Hope this helps, Cordially

Same here: last successful send was around 16:30 today (NAS sending mail to me about switching to UPS and back again after one of those millisecond power-transients that love to fry electronics. Since then: smtpauths.bluewin.ch shows "offline". 0800800800 no help at all...suggested to change password in customer centre: I "changed" it to whatever it was before from my password database: bluewin webmail works fine (but probably does not use smtpauths), multiple Macs & iPhones receive (IMAPS) from bluewin webmail and from other senders, but cannot send (SMTPAUTHS is showing an Offline error). No, I'm not using any variant of MD5 authentication, just password. I do note one change... the current Swisscom instructions say to use "Swisscom" (just Swisscom!!!) as your e-mail address on the first screen for setting up a new mail account (stupid!). My existing accounts all use the real mail address in this position. So... **Hi Swisscom: fix it; and please fix it so it makes sense -- my mail address is \*\*NOT\*\* Swisscom.** Chris EDITED: spell check got in the way -- bluefin.ch!!!

no, it's not authentication settings. **\[EDIT: yes it was...read on\]** no, it's not a password issue. Next suggestion? Chris

@"Tchris"#114038 I would first check that you have the password corresponding to the @Bluewin.ch account. This password is not the same as the one you use to enter the Swissom customer center or your webmail. This password can be reset in the customer center or the mySwisscom App [https://www.swisscom.ch/myswisscom/](https://www.swisscom.ch/myswisscom/) Second I would check, as already suggested here, that you use the setup guide [https://emailsetup.swisscom.ch/guide](https://emailsetup.swisscom.ch/guide) or [www.swisscom.ch/email-update](http://www.swisscom.ch/email-update) Alternatively you can use the following parameters directly (for experienced users) Incoming mail server IMAP4: imaps.bluewin.ch (Port 993) POP3: pop3s.bluewin.ch (Port 995) Use SSL Authentication: Password CRAM/Digest/MD5 deactivated Outgoing mail server SMTP: smtpauths.bluewin.ch (Port 465) Use SSL Authentication method: Password (sometimes also called Normal) CRAM/Digest/MD5 deactivated Hope this helps

@"Schofeungum29"#p652634 @"Black Mamba"#120757 Thanks for the suggestions - all five of my MacAirs have used identical settings that were first established in early 2015 when I switched from Windows to Mac OS. My mail settings **\[EDIT: these settings are NOT obeyed...read on\]** are below -- nothing changed since since configuring two new MacAirs (OS Big Sur) mid-November. IMAPS continues to work. SMTPAUTHS remains "Offline"! ...on BOTH new MacAir. **A new discovery** this morning: I fired up a semi-retired MacAir (OS Mojave)...IMAPS **and** SMTPAUTHS work perfectly using exactly the same mail-settings as the two new MacAirs. **Conclusion**: problem is not with my Mail-settings, WiFi, Network, Firewall, Router, Internet-connect. Something somewhere changed, and killed mail on new-Macs but not on old-Macs. ...investigations continue.

Good morning Tchris, If you could send e-mails yesterday and minutes later from **the same device/client** get an error then it is not related to an MD5 issue. Does it work again now? I quickly looked at [https://www.swisscom.ch/en/residential/help/internet/setting-up-repairing-e-mail.html#](https://www.swisscom.ch/en/residential/help/internet/setting-up-repairing-e-mail.html#)! and could not find the "Swisscom" in the account name you mentioned. Can you let us know where you found this mistake? Cordially

@"Black Mamba"#120757 mmmmmm! new-Mac logs show a lot of update activity on 1st February! ...maybe Apple broke something. Thanks for the German links...I don't read German, but I'll give it a try. Chris
