It sounds like you are looking to use that server as a mail relay.  Take a look at this page:

https://www.citadel.org/relay.html

So I've signed up with Mailjet with appears to offer free SMTP relays for low volume (<200 per day) users.  I've entered the following as a smart host:

While I'm seeing e-mails go out out of the send queue they are not being received.  I've created the SPF and DKIM records as directed by mailjet (which they automatically retrieve and verify) but still my mails are not being received.  

spf = 

v=spf1 include:spf.mailjet.com ?all

Do I need to do any spf configuration on the Citadel server?  Are there any logs I can look at to see what's happening?  Or does anyone have any other thoughts?

Thank you all for your help!

been testing with different style usernames and passwords - still no connection.

I'm not 100% sure if that's the reason or if i misinterpreted things, but since my testing i cannot get my phone to connect to smtp either, so it is not limited to outlook.

Hello,

 

I have exactly the same problem since I updated to build 931 via easyinstall.

Everything works fine except the mail client connection to the SMTP.

 

I would also be very grateful for targeted tips on troubleshooting.

Hello all,

 

Could not find search function in this forum, so apologies if this is a recurring question.

 

Installed Citadel on my PI4, and most of it is working, except i have problems connecting outlook.

I have setup citadel as my mailserver, and i can send and receive email to external accounts (work, gmail, etc). (Test via Webcit)

 

I'm using outlook 2016 and connect via POP3/SMTP.

Outlook collects mail via POP3 fine from the server, using account settings either on port 110 and 995 no problem.

But is keeps asking for my credentials when using SMTP - controlpanel/mailsettings - test account setting - tries to send a test mail.

Tried SMTP via port 25 no encryption, but also using port 465 - with SSL enabled - keeps popping credentials question and port 587 STARTTLS - credentials quesions

'Your email server rejected your login. Verify your user name and password"

email server rejects login using username/password. But they work fine for POP3 logon......

 

Using the same credentials, sending from my Galaxy S10 via wifi on internal network using builtin mailclient using port 465 and SSL is no problem.

So Citadel & Pi should be configured correctly...

 

I'm lost. Any suggestions ?

 

Tnx

 

Bart

 

[Edit]

i've been testing  but no luck yet.

syslog has this error : bad password specified for <> Service <SMTP-MTA>

Should the username not be within those emty brackets ? that would mean the username is not forwarded by outlook to citedal ????

this is the log of one session , as you can see the pop3 session is ok....

Anyone have any idea what might be causing this?
