So your passdb lookup failed. Did you change anything in your configs to adapt to the new syntax ?

Let me read.

I did the conversion and the LLMs are really of no help.

This was quite helpful in my case: https://dovecot.org/upgrader/ LLMs usually proposed outdated syntax. You may paste just a part of your config or the whole config.

I did that. The passwd and userdb are now in question.

We provide a conversion tool at https://dovecot.org/upgrader/ - that might be useful for you.

Did that already.

How about showing the new config then? Might be easier to help fix it.

POP3 specific settings

protocol pop3 {

Don't try to set mails non-recent or seen with POP3 sessions. This is

mostly intended to reduce disk I/O. With maildir it doesn't move files

from new/ to cur/, with mbox it doesn't write Status-header.

pop3_no_flag_updates = yes

Support LAST command which exists in old POP3 specs, but has been removed

from new ones. Some clients still wish to use this though. Enabling this

makes RSET command clear all \Seen flags from messages.

pop3_enable_last = yes

If mail has X-UIDL header, use it as the mail's UIDL.

pop3_reuse_xuidl = yes

Keep the mailbox locked for the entire POP3 session.

pop3_lock_session = no

POP3 UIDL (unique mail identifier) format to use. You can use following

variables, along with the variable modifiers described in

doc/wiki/Variables.txt (e.g. %Uf for the filename in uppercase)

%v - Mailbox's IMAP UIDVALIDITY

%u - Mail's IMAP UID

%m - MD5 sum of the mailbox headers in hex (mbox only)

%f - filename (maildir only)

%g - Mail's GUID

If you want UIDL compatibility with other POP3 servers, use:

UW's ipop3d : %08Xv%08Xu

Courier : %f or %v-%u (both might be used simultaneosly)

Cyrus (<= 2.1.3) : %u

Cyrus (>= 2.1.4) : %v.%u

Dovecot v0.99.x : %v.%u

tpop3d : %Mf

Note that Outlook 2003 seems to have problems with %v.%u format which was

Dovecot's default, so if you're building a new server it would be a good

idea to change this. %08Xu%08Xv should be pretty fail-safe.

pop3_uidl_format = %08Xu%08Xv

Permanently save UIDLs sent to POP3 clients, so pop3_uidl_format changes

won't change those UIDLs. Currently this works only with Maildir.

pop3_save_uidl = no

POP3 logout format string:

%i - total number of bytes read from client

%o - total number of bytes sent to client

%t - number of TOP commands

%p - number of bytes sent to client as a result of TOP command

%r - number of RETR commands

%b - number of bytes sent to client as a result of RETR command

%d - number of deleted messages

%m - number of messages (before deletion)

%s - mailbox size in bytes (before deletion)

%u - old/new UIDL hash. may help finding out if UIDLs changed unexpectedly

pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s

Maximum number of POP3 connections allowed for a user from each IP address.

NOTE: The username is compared case-sensitively.

mail_max_userip_connections = 3

Space separated list of plugins to load (default is global mail_plugins).

mail_plugins = $mail_plugins

Workarounds for various client bugs:

outlook-no-nuls:

Outlook and Outlook Express hang if mails contain NUL characters.

This setting replaces them with 0x80 character.

oe-ns-eoh:

Outlook Express and Netscape Mail breaks if end of headers-line is

missing. This option simply sends it if it's missing.

The list is space-separated.
