I have one account on our internal dovecot server that keeps throwing the same repeated error:

I have tried the following: -Restarting the workstation

• Compacting folders in Thunderbird
• Repaired the Inbox Folder in Thunderbird
• Restarting the dovecot service
• Set the connections in Thunderbird Account settings to not check for messages automatically (manual only)
• Set the user to own all folders and sub-folders in his home directory on the server

I found old message in the archives from 2017 that had the same error but I did not see a posted solution.

dovecot --version 2.2.36 (lfl0bfa63)

config file:

[root@mario2 dovecot]# cat dovecot.conf

Dovecot configuration file

If you're in a hurry, see http://wiki2.dovecot.org/QuickConfiguration

"doveconf -n" command gives a clean output of the changed settings. Use it

instead of copy&pasting files when posting to the Dovecot mailing list.

'#' character and everything after it is treated as comments. Extra spaces

and tabs are ignored. If you want to use either of these explicitly,

put the

value inside quotes, eg.: key = "# char and trailing whitespace "

Most (but not all) settings can be overridden by different protocols

and/or

source/destination IPs by placing the settings inside sections, for

example:

protocol imap { }, local 127.0.0.1 { }, remote 10.0.0.0/8 { }

Default values are shown for each setting, it's not required to uncomment

those. These are exceptions to this though: No sections (e.g.

namespace {})

or plugin settings are added by default, they're listed only as examples.

Paths are also just examples with the real defaults being based on

configure

options. The paths listed here are for configure --prefix=/usr

--sysconfdir=/etc --localstatedir=/var

Protocols we want to be serving.

#protocols = imap pop3 lmtp protocols = imap pop3

A comma separated list of IPs or hosts where to listen in for connections.

"*" listens in all IPv4 interfaces, "::" listens in all IPv6 interfaces.

If you want to specify non-default ports or anything more complex,

edit conf.d/master.conf.

#listen = *, :: listen = *, ::

Base directory where to store runtime data.

#base_dir = /var/run/dovecot/

Name of this instance. In multi-instance setup doveadm and other commands

can use -i <instance_name> to select which instance is used (an

alternative

to -c <config_path>). The instance name is also added to Dovecot processes

in ps output.

#instance_name = dovecot

Greeting message for clients.

#login_greeting = Dovecot ready.

Space separated list of trusted network ranges. Connections from these

IPs are allowed to override their IP addresses and ports (for logging and

for authentication checks). disable_plaintext_auth is also ignored for

these networks. Typically you'd specify your IMAP proxy servers here.

#login_trusted_networks = login_trusted_networks = 10.5.1.0/24

Space separated list of login access check sockets (e.g. tcpwrap)

#login_access_sockets =

With proxy_maybe=yes if proxy destination matches any of these IPs,

don't do

proxying. This isn't necessary normally, but may be useful if the

destination

IP is e.g. a load balancer's IP.

#auth_proxy_self =

Show more verbose process titles (in ps). Currently shows user name and

IP address. Useful for seeing who are actually using the IMAP processes

(eg. shared mailboxes or if same uid is used for multiple accounts).

#verbose_proctitle = no

Should all processes be killed when Dovecot master process shuts down.

Setting this to "no" means that Dovecot can be upgraded without

forcing existing client connections to close (although that could also be

a problem if the upgrade is e.g. because of a security fix).

#shutdown_clients = yes

If non-zero, run mail commands via this many connections to doveadm

server,

instead of running them directly in the same process.

#doveadm_worker_count = 0

UNIX socket or host:port used for connecting to doveadm server

#doveadm_socket_path = doveadm-server

Space separated list of environment variables that are preserved on

Dovecot

startup and passed down to all of its child processes. You can also give

key=value pairs to always set specific settings.

#import_environment = TZ

Dictionary server settings

Dictionary can be used to store key=value lists. This is used by several

plugins. The dictionary can be accessed either directly or though a

dictionary server. The following dict block maps dictionary names to URIs

when the server is used. These can then be referenced using URIs in format

"proxy::<name>".

dict { #quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext #expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext }

Most of the actual configuration gets included below. The filenames are

first sorted by their ASCII value and parsed in that order. The

00-prefixes

in filenames are intended to make it easier to understand the ordering.

!include conf.d/*.conf

A config file can also tried to be included without giving an error if

it's not found:

!include_try local.conf

I need assistance. I appreciate the help.

For what it's worth... I know less than nothing, but a quick search turned up an apparent issue with cpanel which sounds similar:

https://forums.cpanel.net/threads/dovecot-errors.626131/

John Tulp

Here's the output: $ sudo doveadm force-resync -u pstrangfeld "*" doveadm(user): Error: vsize-hdr has invalid size: 36 doveadm(user): Error: vsize-hdr has invalid size: 36

$ sudo doveadm force-resync -u user "*" doveadm(user): Error: vsize-hdr has invalid size: 36 doveadm(user): Error: vsize-hdr has invalid size: 36

I did it twice, the same output comes each time.  Is there something else I should get?  Does this take a while to finish processing?
