Hi,
I have a problem with postfix + dovecot 1:2.3.21+dfsg1-2ubuntu6.3 on Ubuntu Server 24.04:
When using dovecot's imap-login to verify users and passwords againgst dovecot's user list, it doesn't pass the DSN flag through, therefore effectively disabling DSN.
Postfix, submission port bound to 127.0.0.1, port 587:
250-myhostname 250-PIPELINING 250-SIZE 18432000 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250-DSN 250-SMTPUTF8 250 CHUNKING
but imap-login (configured to forward to 127.0.0.1:587):
250-myhostname 250-8BITMIME 250-AUTH PLAIN 250-BURL imap 250-CHUNKING 250-ENHANCEDSTATUSCODES 250-SIZE 250 PIPELINING
So both the size limit and DSN are not passed through, SMTPUTF8 either.
Even setting
imap_capability = +DSN
in 20-imap.conf doesn't help.
What is keeping dovecot's imap-login from offering DSN?
best regards
Hadmut
