dovecot 2.4 issue with openssl >= 3.0.8
by Michal Hlavinka 22 Aug '23

22 Aug '23

Hi, I've started testing main git branch and found an issue with openssl 3. Test suite fails: test_load_v1_key ........................................... : ok test-crypto.c:445: Assert failed: ret == TRUE test-crypto.c:446: Assert failed: error == NULL Panic: file dcrypt-openssl3.c: line 2917 (dcrypt_openssl_public_key_type): assertion failed: (key != NULL && key->key != NULL) Error: Raw backtrace: test-crypto(+0x5af01) [0x55951b667f01] -> test-crypto(backtrace_get+0x2f) [0x55951b66877f] -> test-crypto(+0x31291) [0x55951b63e291] -> test-crypto(+0x312d5) [0x55951b63e2d5] -> test-crypto(+0x16025) [0x55951b623025] -> libdcrypt_openssl.so(+0x70ff) [0x7f5a995b60ff] -> test-crypto(+0x2a17b) [0x55951b63717b] -> test-crypto(+0x3055d) [0x55951b63d55d] -> test-crypto(test_run+0x6c) [0x55951b63d61c] -> test-crypto(main+0x4e) [0x55951b62b66e] -> libc.so.6(+0x27b4a) [0x7f5a995eeb4a] -> libc.so.6(__libc_start_main+0x8b) [0x7f5a995eec0b] -> test-crypto(_start+0x25) [0x55951b62b7e5] The issue is caused by change in openssl >= 3.0.8 in lib-dcryt/dcrypt-openssl3.c method ec_key_get_pub_point_hex(...) in old version (for openssl 1.x) it uses compressed format: EC_POINT_point2hex(g, p, POINT_CONVERSION_COMPRESSED, NULL); in openssl3 version it uses EVP_PKEY_get_octet_string_param(pkey, OSSL_PKEY_PARAM_PUB_KEY, buf, sizeof(buf), &len); but key is created in dcrypt_evp_pkey_from_point(...) with OSSL_PKEY_PARAM_EC_POINT_CONVERSION_FORMAT, "uncompressed" this was working in openssl pre 3.0.8 as compression format was ignored when dumping data and used always compressed format. From https://www.openssl.org/docs/man3.0/man7/EVP_KEYMGMT-EC.html """ Before OpenSSL 3.0.8, the implementation of providers included with OpenSSL always opted for an encoding in compressed format, unconditionally. Since OpenSSL 3.0.8, the implementation has been changed to honor the OSSL_PKEY_PARAM_EC_POINT_CONVERSION_FORMAT parameter, if set, or to default to uncompressed format.""" I don't see simple way how to force compressed format just for dumping data without effecting the key itself. Method that can be used with compression format argument is EC_POINT_point2hex but it requires quite lengthy extraction of EC_POINT first. I've tried this for testing with: static const char *ec_key_get_pub_point_hex(const EVP_PKEY *pkey) { if (!EVP_PKEY_is_a(pkey, "EC")) return NULL; size_t len; EVP_PKEY_get_utf8_string_param(pkey, OSSL_PKEY_PARAM_GROUP_NAME, NULL, 0, &len); buffer_t *parambuf = t_buffer_create(len+1); EVP_PKEY_get_utf8_string_param(pkey, OSSL_PKEY_PARAM_GROUP_NAME, (char *)parambuf->data, len+1, &len); int nid = OBJ_txt2nid(parambuf->data); EVP_PKEY_get_octet_string_param(pkey, OSSL_PKEY_PARAM_PUB_KEY, NULL, 0, &len); parambuf = t_buffer_create(len+1); EVP_PKEY_get_octet_string_param(pkey, OSSL_PKEY_PARAM_PUB_KEY, (unsigned char *)parambuf->data, len+1, &len); EC_GROUP *ec_grp = EC_GROUP_new_by_curve_name(nid); if (ec_grp == NULL) return NULL; EC_POINT *point = EC_POINT_new(ec_grp); if (point == NULL) { EC_GROUP_free(ec_grp); return NULL; } if (!EC_POINT_oct2point(ec_grp, point, parambuf->data, len, NULL)) return NULL; char *ret = EC_POINT_point2hex(ec_grp, point, POINT_CONVERSION_COMPRESSED, NULL); EC_GROUP_free(ec_grp); EC_POINT_free(point); return ret; } and it fixed the issue, but there may be an easier way how to achieve that.

Question about namespaces
by J Doe 21 Aug '23

21 Aug '23

Hello, I have a question regarding namespaces. My current dovecot.conf is rather basic when it comes to namespaces - I have one private namespace per user: namespace inbox { type = private separator = / inbox = yes hidden = no list = yes subscriptions = yes } I have some users who connect via more than one client - for instance, some use Apple Mail in addition to Roundcube. I have noticed that different mail clients sometimes create similar mailboxes, such as Trash and Deleted Items. I would like the same mailboxes across any client, so I am wondering if there is a way in Dovecot to specify the folders and have the *client* not create them. For instance, a config in dovecot.conf that specifies a Trash folder and the mail clients cannot create "Deleted Items", etc. in addition to this. Is this possible ? Thanks, - J

Backing up m(d)box - rsync?
by donotspam＠fastmail.fm 19 Aug '23

19 Aug '23

Hello, I manage a small number of email accounts for a voluntary organisation on a shared hosting platform. $ dovecot --version 2.3.13 (89f716dc2) I would like to keep automated local backups, but do not have access to doveadm. I have seen a couple of forum posts where users have have suggested that using rsync to backup m(d)box folders can corrupt dovecot's indexes, but there is no further explanation, and this is apparently not a problem for maildir. Our host seems to use mdbox. Does doveadm provide some sort of transaction/locking mechanism to prevent consistency problems? Others seem to recommend using tar but I don't see what difference that should make. Given that cpanel backups (provided as tar.gz archives of the home directory) include mail/ and seem to be copies of the filesystem at a particular time (though not true "snapshots" as such), aren't these just as "safe" as an rsync-ed backup? Can anyone confirm/deny/shed any light on the issue(s), if indeed any? Many thanks, Gareth

last_login using fs:posix does not autocreate the last-login directory
by karl＠denninger.net 13 Aug '23

13 Aug '23

I am using the last_login plug-in on a relatively small system to populate the last access time for users in the directory format. I don't want to have this go into an SQL database or similar as the userbase is small and shell access to the information for other purposes is useful. I have this in the conf.d directory under the configuration dir in 20-lastlogin.conf: protocol imap { mail_plugins = $mail_plugins last_login } plugin { last_login_dict = fs:posix:prefix=/var/run/dovecot/ } This works except that while the prefix is there the "last-login" directory under the prefix gets removed on restart (as you think it might) and I can't find an example of how to have it auto-created. This results in a bunch of logged errors until I re-create that working directory under the base. Am I missing something obvious?

sso / sharing authenticated sessions how does it work
by Marc 12 Aug '23

12 Aug '23

I am totally not experienced with setting up sso etc. I was wondering if/how it is possible to share an authenticated session between dovecot and the mail client with the webmail so a user does not need to login again.

Dovecot and Thunderbird 15
by Elise 10 Aug '23

10 Aug '23

Hi, I recently had some issues with Thunderbird 15 when removing e-mail. With my other mailclient Outlook I could without any issue. As I don't grand POP3 mail pickup, I disabled that in dovecot.conf #service pop3-login { # inet_listener pop3 { # address = 10.10.10.52 # } # inet_listener pop3s { # address = 10.10.10.52 # } #} Enabling the above and restarting Dovecot solved the issue. Is it TB related or do I overlook a config parameter? E.

Question about custom flags
by d.meister-braeuer＠heinlein-support.de 09 Aug '23

09 Aug '23

Hello all, RFC3501 describes among other things that custom flags can be set for mails. These can be allowed or forbidden in the server: "Servers MAY permit the client to define new keywords in the mailbox". When I am on our server, it also looks like dovecot basically allows this: a select INBOX FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded Old $ITipAnalyzed $ITipProcessed Forwarded NonJunk $cl_1 $cl_2 $cl_3) OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded Old $ITipAnalyzed $ITipProcessed Forwarded NonJunk $cl_1 $cl_2 $cl_3 \*)] Flags permitted. The only option that goes in this direction is this one: mail_max_keyword_length But basically describes something else as well, if I see it correctly. Is there a way to prevent dovecot from giving custom flags, or what is the name of the parameter where you can set this? Best
