Can't send mails over imap.vivaldi.net with Thunderbird anymore
Hello, after trying to set the new settings from here in the forum. I get an error message when sending a mail that the server answered with a false message. I can't paste it here because the spam filter is not allowing it. It just starts with "OK [CAPABILITY IMAP4rev1..."
Thank you for helping.
Thats the full server message:
OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN AUTH=LOGIN] Dovecot ready..
That message is unexpected by Thunderbird, so its not sending mails.
Vivaldi changed the servers: you need to manually change them in Thunderbird settings.
Choose one of the two servers, below (incoming server):
IMAP: imap.vivaldi.net, Port: 143, Authentication method: normal password, Connection security: STARTTLS
POP3: pop3.vivaldi.net, Port: 110, Authentication method: normal password, Connection security: STARTTLS
...or, instead, one of the following (incoming server):
IMAPs: imap.vivaldi.net, Port: 993, Authentication method: normal password, Connection security: SSL/TLS
POP3s: pop3.vivaldi.net, Port: 995, Authentication method: normal password, Connection security: SSL/TLS
Set the following sending server (outgoing server):
SMTP: smtp.vivaldi.net, Port: 587, Authentication method: normal password, Connection security: STARTTLS
@newscpq I don't know, I don't keep track of this area of the forums.
Ah, nice. Thank you. Why was there no information mail about this? Changing servers issnt nice :(
@filla-it There was notice in a blog post and in an email sent to users.Reply Quote 1 1 Reply Last reply

@filla-it splitting SMTP and IMAP servers is not possible with an identical DNS entry.
The alternate approach would have been to not be able to receive mails with the old (
mail.vivaldi.net) client settings.
The interesting question would be how Thunderbird managed to:
- detect there is no longer a SMTP server on
- fails to give the user any useful information about that error
- try an IMAP port instead
- complain when it gets the correct server message for that port.
Or is there some (failing) autoconfig mechanism on
vivaldi.netI am missing?
- no ISPDB entry
- (bad) main site redirect for config server endpoints
- no SRV records
- detect there is no longer a SMTP server on
Why was there no information mail about this?
There was: you should have an e-mail in your inbox, but it was rather late (sent the same day of the change) and ambiguous: the subject deals with a "scheduled downtime" (that usually isn't a server change) and about some change in "mailbox settings".
I think they could have done it much better
The only way for Thunderbird is: to check common subdomains like smtp,. pop3 or imap to guess the server domain.
Other detection methods are not active on mail server as i know.Reply Quote 0 1 Reply Last reply
@filla-it We apologize for the changes and trouble you have with the changes.
You say you "send mails over imap.vivaldi.net". But outgoing (=sending) mails are over smtp... May be i misunderstood your post.
Please tell me, can you use IMAP now with the new server settings?Reply Quote 0B1 Reply Last reply
By the looks of it: Entered the IMAP settings for SMTP.

@filla-it May be you typed in the wrong server!?
For sending/outgoing mail you need to use server domain
smtp.vivaldi.neton Port 25 (or Port 587) with STARTTLS!Reply Quote 0 1 Reply Last reply
@gwen-dragon and also the wrong port if he can connect and gets an IMAP status message. ☺
@filla-it port 587 for mail submission is preferred.
@gwen-dragon port 25 should only be used for Server2Server transport (e.g. Vivaldi server → Google server), in essential, endpoints with MX records.
There may be differents in feature sets for port 25 and 587 (login, accepting mails from/for foreign mail adresses).
@gwen-dragon port 25 should only be used for Server2Server transport
I know, dear. I am a server admin on my own root servers.
But you are right, the Submission port 587 should be used as Standard for users sending by SMTP.Reply Quote 0B1 Reply Last reply

I could have guessed. It was ment as a general remark and should not have been directed at you.
Can I get away with blaming bad wording over my surprise about you referring to a non-optimal configuration? 😇
Ich hätte keine Einwände falls Du vor hast unser Überkreuz-In-die-Antwort-fallen der letzen Stunde weg- oder aufzuräumen 😁.
Bin leider zu modlos das selber jetzt noch in einer Form zu machen damit es am Ende nachvollziehbarer für Andere wird.
@becm No need to remove your post. All ok, no bad wording. We are human (almost, except the Gwen-Dragon) ;)
