“SOGo sends an empty "AUTH PLAIN"”
That’s ok from the spec https://datatracker.ietf.org/doc/html/rfc4954#section-4 SOGo only send the AUTH PLAIN, server should reply with a code 334 Then sogo send the credentials. So my guess is that your smtp server doesn’t support that. -- Quentin Hivert || Alinto || R&D Lead Developer 19 Quai Perrache 69002 Lyon <http://www.alinto.com> www.alinto.com From: [email protected] <[email protected]> On Behalf Of Pfennig Sent: mercredi 14 mai 2025 16:38 To: qhivert ([email protected]) <[email protected]> Subject: Re: [SOGo] External SMTP with user auth Thank you for the input. Especially > Yes I will use the email instead of the uid but with the user password still. this is important to know. I was doubting that. Unfortunately, it is still not working. I also tried setting the master user, but I am not sure, whether it works or not. How can I trigger an action, that would use the master user instead of the normal user? As stated in my first message, SOGo sends an empty "AUTH PLAIN" request to the mail server. Is it possible to see the SOGo part of that interaction? Maybe the mail field or the password field is not properly set due to using LDAP? Thanks in advance!

What is not clear to me from the documentation is whether, apart from using the primary email address of the user, it will also use the user's password to authenticate. But you can use a master user as the documentation says: ``` If your mail server requires use of SMTP AUTH, you can use the following parameters in the configuration file : SOGoSMTPMasterUserEnabled = YES; SOGoSMTPMasterUserUsername = "foo"; SOGoSMTPMasterUserPassword = "bar"; ``` On Tue, May 13, 2025 at 6:52 PM Pfennig <[email protected] <mailto:[email protected]> > wrote: Hi! I am not using postfix, but planned to communicate directly with my external (hosted) mail server via SMTP. The credentials are the same everywhere and seem to be working, since the IMAP is working and I can see my emails. But maybe I am misunderstanding something. No mails can be send in general, also no notification with the SMTPMasterUser... The SMTP is tested and works with PLAIN auth with the credentials, that I also use for login.
