Good morning to all i guess things have changed yet again to keep this simple : i buy a certificate (example) : mail.paulkudla.net i generated the key / csr as per normal using data = '/usr/local/bin/openssl req -new -key /tmp/temp.key -out /tmp/temp.csr -subj "/C=%s/ST=%s/L=%s/O=%s/CN=%s"' %(country,state,location,organization,self.domain) please note the above is done in django (yes i am running thunderbird v102) i go buy the certificate i database the CRT & CA CSR is : -----BEGIN CERTIFICATE REQUEST----- MIICpzCCAY8CAQAwYjELMAkGA1UEBhMCQ0ExEDAOBgNVBAgMB09udGFyaW8xDzAN

keep in mind that the cert purchased is only for the name : mail.paulkudla.net thus i fail to see why it is throwing error 42, however this seems to be a patch to thunderbird as well i did not have to

One-off backup
by Ian Evans 11 Oct '22

11 Oct '22

I run a small email server for me and the missus. Six dovecot users. Our host is migrating our server instance. They usually (99.9999% lol) go off without a hitch. As we don't have dovecot running elsewhere, I'm assuming doveadm is the wrong tool. If we want to make a one-off backup prior to the migration, is shutting down postfix and running tar czf mailstorage.tgz /path/to/mail okay? Thanks.

Static build problems
by Jacob Welsh 09 Oct '22

09 Oct '22

I'm attempting to build the latest Dovecot, version 2.3.19.1, on Gales Linux, a distribution based on musl libc with all static linking. After working around some expected troubles to generate configure, such as the libtool and iconv.m4 dependencies, the build appeared to complete successfully. But on closer inspection, the plugins were installed as a bunch of .a and .la files rather than getting linked into any of the binaries, as would be necessary to actually use them. I determined that the probe for dynamic module support (DOVECOT_MODULES defined in 'm4/modules.m4') had returned a false positive: in the static configuration musl includes a stub dlopen() that always returns failure at runtime, so a compile-and-link-only test is not predictive. Libtool itself is affected in the same way, but it comes with the --disable-shared option which usually makes things works fine. Short of a proper solution (perhaps removing modules.m4 and going instead by what libtool already determined, since you've decided to depend on it anyway), I stubbed out modules.m4 to simply return the correct result for this platform, thus: AC_DEFUN([DOVECOT_MODULES], [ have_modules=no AC_SUBST(MODULE_LIBS) AC_SUBST(DLLIB) ]) Now the build is failing due to the absence of a function that's defined only when HAVE_MODULES is true: libtool: link: gcc -I../../src/lib -I../../src/lib-test -I../../src/lib-ssl-iostream -DDCRYPT_MODULE_DIR=\"/gales/pkg/dovecot-0.0-2.3.19.1/lib/dovecot\" -DDCRYPT_SRC_DIR=\"../../src/lib-dcrypt\" -std=gnu99 -g -O1 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -Wl,--whole-archive -Wl,../lib-ssl-iostream/.libs/libssl_iostream.a -Wl,--no-whole-archive -o test-stream test_stream-dcrypt.o test_stream-istream-decrypt.o test_stream-ostream-encrypt.o test_stream-test-stream.o ../lib-ssl-iostream/.libs/libssl_iostream.a ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a test_crypto-dcrypt.o: In function `dcrypt_initialize': /home/user/gales-linux/gports/dovecot/build/dovecot-2.3.19.1/src/lib-dcrypt/dcrypt.c:34: undefined reference to `module_dir_try_load_missing' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:664: test-crypto] Error 1 I noticed commit d21897832a443d139d56b1fb1c86d8f76e5f77f3 from 2009, "Fixed compiling without module support", and clearly it's supposed to work since the #ifdefs are there, but I begin to suspect that nobody's actually tested this branch of the configuration tree recently. Further, looking through the automakefiles I'm not finding how the plugin libraries are supposed to work at all in this case and I begin to fear that they simply... aren't. Say it ain't so? Jacob

imapsieve removeflag ignored
by Slavko 08 Oct '22

08 Oct '22

Hi, i have working SPAM reporting implementend by imapsieve in debian's 2.3.13 dovecot. Recently i decide to add personal spam filter by bogofilter and use logic to learn/unlearn SPAM/HAM based on message flags. Here is example of moving message from Junk folder (the opossite logic is similar): if hasflag "$Junk" { execute :pipe "bogofilter" ["-Sn"]; removeflag "$Junk"; debug_log "Learned HAM (and unlearned)"; } else { execute :pipe "bogofilter" ["-n"]; debug_log "Learned HAM (only)"; } # mark as learned addflag "$NotJunk"; report ... When i move message, the debug lines in log shows, that logic works and flag is added as expected, but the other flag is not removed. Thus after moving mail from Junk, which has $Junk flag, it has both flags, the $Junk and $NotJunk. I tried to move removeflag action outside of condition and add it just before addflag, but the result is the same. For now i do not know if here is something wrong in my script, or i did some other mistake. On IRC cmouse tell, that removeflag was fixed in some early version (2.3.5 or so), but it doesn't work here. Please, how i can get it working? regards PS: please CC me, i am not subscribed -- Slavko https://www.slavino.sk/

Replacing antispam plugin with IMAPSieve not 100% correct?

04 Oct '22

I think this page[1] is not correct If you configure this option: imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve the file report-spam.svbin cannot be created because users cannot write there.

Using sqlite as dict for last_auth plugin
by Oleg petol 04 Oct '22

04 Oct '22

Hi! It is required to collect statistics about the time of the last IMAP and POP3 login of the user and the delivery of letters to him via lmtp. The last-login plugin is perfect. But I don't want to use heavy databases as the mail system service is served by the Oracle DB. The most suitable option, as I see, is to store statistics in the sqlite DB, but after going through all the options in the configuration file, I could not use sqlite. When writing in configuration: plugin { driver=sqlite last_login_dict = sqlite:statsdb last_login_key = last-login/%s/%u/%r last_login_precision = ms } I am getting an error: Oct 4 17:01:41 nms4 dovecot: imap(new_ver_test(a)test2.aroma.ru)<154597><q0VJ5jXq9o4KAQDI>: Error: last_login_dict: dict_init(sqlite:statsdb) failed: Unknown dict module: sqlite I did the last-login plugin setup exactly according to the instructions: https://doc.dovecot.org/configuration_manual/mail_location/obox/last_login_… I am using standard debian packages. Desperate, I built latest dovecot version from source, but got exactly the same error. Tell me, please, is it possible to use a dictionary in sqlite format to collect last-login plugin statistics? And how should I describe it in the configuration file?

Good Morning Michael, No problem. Although, to be clear I didnt point out anything, but its Sébastien and the credit shall go for him. Also, by the way in EXIM MTA, there is verify syntax condition in data acl, which checks all email headers and validate that they are standards compliant and reject sending any email beforehand to your issue which has non-compliant header and offers the ability to remove such headers with condition handling e.g. if contained any Sieve header, to request removing message id headers with headers_remove and add compliant one with add_header, and I guess this will mitigate any mail service provider rejection issue. If you are postfix user and considering switching, let me know, I might be able to help. Zakaria.
