mail_max_userip_connections per remote IP not working
by Alessio Cecchi 16 Apr '21

16 Apr '21

Hi, I'm tryng to set a specific mail_max_userip_connections for a remote IP (webmail IMAP software), but it seems not working: remote 1.2.3.4 { protocol imap { mail_max_userip_connections = 100 } } and also this isn't working remote 1.2.3.4 { mail_max_userip_connections = 100 } I insert it at the end of 20-imap.conf file. Is something wrong or is not supported? I'm running dovecot 2.3.14. Thanks -- Alessio Cecchi Postmaster @http://www.qboxmail.it https://www.linkedin.com/in/alessice

altmove reverse doesn't work

I am having troubles with moving emails from alternative storage to primary storage.

Auth Cache for checkpassword
by Amol Kulkarni 14 Apr '21

14 Apr '21

Hello, I use the checkpassword driver for imap/pop authentication. To improve the performance I would like to enable authentication caching for it. However just adding the auth_cache_size and auth_cache_ttl doesn't work. No entries are cached. If I add a cache directive in the passdb, then the service doesnt start. I was wondering if the authentication caching is supported for the checkpassword driver. Please point me in the right direction. Thanks in advance, Amol

Tuning pop3-login client_limit
by Martin Olsen 13 Apr '21

13 Apr '21

Good day / evening / morning good dovecot people: Overview: We are seeing the following issue on one of our servers: pop3-login: Error: master(pop3): net_connect_unix(pop3) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable (client-pid=5418, client-id=1, rip=__REMOVED__, created 534 msecs ago, received 0/4 bytes) We tried tuning the pop3-login -> client_limit parameter. However, as soon as we increased this parameter (and after restarting dovecot), we saw an onslaught of lmtp connection errors in postfix (unable to deliver via lmtp to dovecot). This led us to set the pop3-login -> client_limit back to 1000 again and the lmtp errors disappeared. This leads me to think that we should tune some other parameters as well. Increase overall limits or such. It seems like when increasing the client_limit for pop3-logins that somehow affected the lmtp deliverability. If anyone has any input on this that would be much appreciated. Cheers, Martin -- Version and config: # dovecot --version 2.2.36 (1f10bfa63) # dovecot -n # 2.2.36 (1f10bfa63): # OS: Centos 7.7 # Hostname: auth_mechanisms = auth_verbose = yes base_dir = __REMOVED__ default_client_limit = 2500 disable_plaintext_auth = no doveadm_password = first_valid_uid = 89 last_valid_uid = 89 lmtp_rcpt_check_quota = yes login_greeting = login_trusted_networks = mail_gid = 89 mail_plugins = " notify replication quota" mail_uid = 89 mbox_write_locks = fcntl namespace inbox { inbox = yes location = prefix = } passdb { args = driver = ldap } plugin { mail_replica = tcps: quota = maildir:User quota quota_rule = } protocols = pop3 lmtp replication_full_sync_interval = 3 hours replication_max_conns = 20 service aggregator { fifo_listener replication-notify-fifo { group = postfix mode = 0640 user = postfix } unix_listener replication-notify { group = postfix mode = 0640 user = postfix } } service auth { unix_listener auth { mode = 0660 } } service doveadm { inet_listener { port = 12345 ssl = yes } } service lmtp { process_min_avail = 10 unix_listener lmtp { group = postfix mode = 0640 user = postfix } } service pop3-login { client_limit = 1000 process_limit = 2048 process_min_avail = 10 service_count = 1 } service pop3 { client_limit = 1 process_limit = 2048 process_min_avail = 0 service_count = 1 }

json_parse_number broken by compiler optimization
by Christian Ehrhardt 13 Apr '21

13 Apr '21

Hi, the recent Ubuntu (re)builds uncovered an issue with dovecot 1:2.3.13+dfsg1-1 build log: https://launchpadlibrarian.net/529849650/buildlog_ubuntu-hirsute-amd64.dove… A coworker tried 2.3.14 but got the same result. What fails is the json_parser build time test like: test-json-parser.c:161: Assert(#25) failed: null_strcmp(json_output[pos].value, value) == 0 I was looking into that a bit more and what I found is that it is dependent on the new toolchain of gcc 10.2.0-1. Not all calls to json_parse_* fail, e.g. the first one looks all good and passes I was iterating the tests using a report function defined like (gdb) define repcon >c >p pos >p json_output[pos].type >p type >p json_output[pos].value >p value >call null_strcmp(json_output[pos].value, value) >end The first one to be bad was: Breakpoint 2, test_json_parser_success (full_size=<optimized out>) at test-json-parser.c:161 161 test_assert_idx(null_strcmp(json_output[pos].value, value) == 0, pos); $84 = 25 $85 = JSON_TYPE_NUMBER $86 = JSON_TYPE_NUMBER $87 = 0x555555633b25 "-12.456" $88 = 0x555555693110 "" $89 = 45 Earlier and later parsing was happy, for example Breakpoint 2, test_json_parser_success (full_size=<optimized out>) at test-json-parser.c:161 161 test_assert_idx(null_strcmp(json_output[pos].value, value) == 0, pos); $90 = 27 $91 = JSON_TYPE_NUMBER $92 = JSON_TYPE_NUMBER $93 = 0x555555633b32 "12.456e9" $94 = 0x555555693110 "12.456e9" $95 = 0 (gdb) We have two things we compare here. 1. json_output[] which is a static define and for this value is 67 »···{ JSON_TYPE_NUMBER, "-12.456" }, 2. the return value that json_parse_next returns. 25 »···" \"sub2\":-12.456,\n" 148 »···»···»···»···ret = json_parse_next(parser, &type, &value); I tried a non negative number and got success which is suspicious Breakpoint 5, test_json_parser_success (full_size=<optimized out>) at test-json-parser.c:164 164 test_assert_idx(null_strcmp(json_output[pos].value, value) == 0, pos); $122 = 25 $123 = JSON_TYPE_NUMBER $124 = JSON_TYPE_NUMBER $125 = 0x555555633b2c "12.456" $126 = 0x555555693110 "12.456" $127 = 0 (gdb) Also the return value otherwise LGTM, it is recognized as a number: 540 } else if ((ret = json_parse_number(parser, value_r)) >= 0) { (gdb) n 541 *type_r = JSON_TYPE_NUMBER; So parsing worked one might think, but the value was not set. (gdb) p *value_r $833 = 0x555555693110 "" It turns out json_parse_number is too optimized. Too optimized for debugging further into json_parse_number. But also optimization is causing the issue. With -O0 or -O1 it works fine, even putting the lower optimization level just around json_parse_number it is enough to avoid the issue. Not a fix but "avoidance" for now: --- a/src/lib/json-parser.c +++ b/src/lib/json-parser.c @@ -386,6 +386,8 @@ static int json_parse_int(struct json_pa return 1; } +#pragma GCC push_options +#pragma GCC optimize ("-O0") static int json_parse_number(struct json_parser *parser, const char **value_r) { int ret; @@ -415,6 +417,7 @@ static int json_parse_number(struct json *value_r = str_c(parser->value); return 1; } +#pragma GCC pop_options static int json_parse_atom(struct json_parser *parser, const char *atom) { I was trying to see what happened and tracked each str_append_c that happened inside json_parse_number. A breakpoint on str_append_c and backtraces showed that we clearly do the "right" parsing. From the backtraces I've seen it does (just from positions): For example (gdb) bt #0 str_append_c (chr=<optimized out>, str=0x5555556930d0) at str.h:44 #1 json_parse_digits (parser=<optimized out>) at json-parser.c:366 => that is a digit It does "- digit digit dot digit digit digit" This perfectly matches the input value, but still the result stays empty: (gdb) p (char*)(str->data) $738 = 0x555555693110 "" In comparison - when parsing the latter 12.456e9 which works I see two odd things: 1. the value isn't cleared despite str_truncate(parser->value, 0); at the beginning of json_parse_number 2. the value (this time) is read exactly as I assumed Breakpoint 17, json_parse_number (value_r=0x7fffffffe1a0, parser=0x555555692ee0) at json-parser.c:394 394 str_truncate(parser->value, 0); Breakpoint 18, str_append_c (chr=<optimized out>, str=0x5555556930d0) at str.h:44 44 buffer_append_c(str, chr); (gdb) p (char*)(str->data) $741 = 0x555555693110 "sub3" ^^ not cleared, still has "sub3" even later on Breakpoint 18, str_append_c (chr=<optimized out>, str=0x5555556930d0) at str.h:44 44 buffer_append_c(str, chr); (gdb) p (char*)(str->data) $742 = 0x555555693110 "1ub3" ^^ reading left to right one char at a time "over the old value", which didn't update the data. So it seems in json_parse_number the ordering of a) str_truncate(parser->value, 0); b) the parsing itself is messed up by optimization. We already know from the above that reducing just this function to -O1 or less avoids the issue. But what is it really - I don't know? Maybe you have a better idea what is going on, the issue should be reproducible when building dovecot with the toolchain present on the latest Ubuntu being 21.04 (Hirsute) right now. -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd

Letsencrypt/OpenSSL test - Verify return code: 21
by Brady Shea 12 Apr '21

12 Apr '21

OS: Ubuntu 20.04.2 (on mutli-core VM) Dovecot (Ubuntu default/repo version): 2.3.7.2 (3c910f64b) OpenSSL (Ubuntu default/repo version): 1.1.1f 31 Mar 2020 Reproducing- Run: "openssl s_client -showcerts -connect imap.example.com:993 -servername imap.example.com" (using a diff domain obviously) Produces error: "Verify return code: 21 (unable to verify the first certificate)" (Meaning it is missing a CA verify from what I understand?) The "Verify return code: 21" error ONLY came to my attention after I had a customer complain about adding an email account to an Android phone (using the Google/Gmail default email app). -> "Certificate cannot be trusted" was shown by app when verifying imap connection. I could force it to be used, but this still bothered me, obviously. *The same certificate bundle is also used by smtp/postifx and www/nginx and works just fine. Also the openssl test shows 'verified' on both* I am posting to list mainly because on an older version of Dovecot I have running (default repo version for Ubuntu 18), I do not have this problem shown during testing with openssl. I did not have to change the ssl_cert or ssl_ca value in config. It has identical local.conf settings other than that. Granted it is also an older openssl version, too. So, I feel this may be a bug with Dovecot (or possibly OpenSSL). I finally 'fixed' it myself by using the LE 'fullchain.pem' certificate as the location for the 'ssl_cert' entry (and chain.pem for the ca entry). Previously, it was using the normal cert.pem file location. This is still the way it's setup on the other older machine and still works fine. Changes- |ssl_ca = </etc/letsencrypt/live/{CertName}/chain.pem (or 'fullchain.pem' should work) *ssl_cert = </etc/letsencrypt/live/{CertName}/fullchain.pem* (was 'cert.pem' previously) ssl_key = </etc/letsencrypt/live/{CertName}/privkey.pem| You can also view the problem here for more info : https://superuser.com/a/1640778/47628 Thanks ahead for any insight into this..

connection closed every ten minutes
by Marco Fioretti 12 Apr '21

12 Apr '21

Greetings, I use mutt on Ubuntu to access my IMAP mailboxes, on my Centos email server that runs dovecot. Everything has worked without problems for years. About one week ago, the connection between mutt and dovecot became unstable. Before, I could leave mutt connected for days in a row, no problem. Now, everything still works fine, except... I get every ten minutes I get "connection timed out" in Mutt's status line, and hundreds of messages like Apr 12 16:12:49 SERVERNAME dovecot: imap(ACCOUNTNAME): Logged out in=164 out=757 what puzzles me is that I did not touch anything both on my server and on my desktop, except an "apt-get update" some days before this started. But cannot see how it would be related anyway, nor have I found anything online like this. Any help to understand what happened and fix it is very welcome. Marco
