by David Mehler 26 Jul '19

26 Jul '19

Hello, Does anyone have this combination going? I'm running freebsd and dovecot, to which i'd like to add solr text search. I am stuck on xml schema integration, if anyone has any notes i'd appreciate them. Thanks. Dave.

dsync crash
by tono 25 Jul '19

25 Jul '19

Hello, I am getting a persistent seg fault while trying to sync our server to a new location. We are on 2.2.33.2, due for an upgrade but we have used dsync successfully in the past. In fact, we used it to populate this same instance. So I hope this is just a configuration issue. My logs are being filled with these errors:: 2019-07-10T08:29:53-04:00 localhost dovecot: [ID 583609 mail.crit] doveadm: Fatal: master: service(doveadm): child 44707 killed with signal 11 (core dumped) On the remote we see: 2019-07-10T10:17:24-04:00 localhost dovecot: [ID 583609 mail.error] doveadm: Error: read(111.111.111.111) failed: EOF (version not received) I tried doing sync manually: truss -rall -wall -f doveadm sync -u tpyro(a)metro-email.com tcp:123.123.123.123 55440: V E R S I O N\t d o v e a d m - s e r v e r\t 1\t 1\n 55440: pollsys(0x0816EB88, 1, 0x00000000, 0x00000000) = 1 55440: read(10, " -\n", 8192) = 2 55440: write(10, 0x08126598, 31) = 31 55440: P L A I N\t P A S s w o R d R E D A C t E D x W o e N X H h\n 55440: read(10, 0x0814980A, 8190) Err#11 EAGAIN 55440: pollsys(0x0816EB88, 1, 0x00000000, 0x00000000) = 1 55440: read(10, 0x0814980A, 8190) = 27 55440: V E R S I O N\t d o v e a d m - c l i e n t\t 1\t 1\n 55440: read(10, 0x08149825, 8163) Err#11 EAGAIN 55440: pollsys(0x0816EB88, 1, 0x00000000, 0x00000000) = 1 55440: read(10, " +\n", 8163) = 2 55440: write(10, 0x081738D0, 60) = 60 55440: \t u s e r 1 @ d o m a i n - n a m e . c o m\t d s y n c - s e r 55440: v e r\t - u u s e r 1 @ d o m a i n - n a m e . c o m\n 55440: pollsys(0x0816EB88, 1, 0x00000000, 0x00000000) = 1 55440: Incurred fault #6, FLTBOUNDS %pc = 0xFEC84490 55440: siginfo: SIGSEGV SEGV_MAPERR addr=0xD89CDB4E 55440: Received signal #11, SIGSEGV [default] 55440: siginfo: SIGSEGV SEGV_MAPERR addr=0xD89CDB4E I saw the note in the wiki about "dovecot --hostdomain" so I made sure they do not match.

lmtp with non ASCII Parameters changed in dovecot 2.3
by Matthias Lay 25 Jul '19

25 Jul '19

Hi, I updated from 2.2 to 2.3 and noticed lmtp rejects parameters containing non ASCII now. this worked with dovecot-2.2 lmtp. the string is already denied after reading in "smtp_command_parse_parameters()" mail from:<bluö> 500 5.5.2 Invalid command syntax is there a plan to change this behaviour, or to implement the SMTPUTF8 extension in lib-smtp? I guess thie would fix Michals "Dovecot LMTP rejecting mail from address with apostrophe" Problem too. Greetz Matze

The version of dovecot in freebsd ports tree is still 2.3.6, any idea when this will be updated to 2.3.7? -- "I can't see the point in the theatre. All that sex and violence. I get enough of that at home. Apart from the sex, of course." - Baldrick

Fwd: Character not allowed in mailbox name
by Lothar Schilling 23 Jul '19

23 Jul '19

Hi Arnold, thanks for your assistance. I solved the issue right now by changing prefix = Shared/%%u/ to prefix = Shared/%%n/ This omits the @mydomain.de part which holds the dot causing the trouble. Why this became a problem due to the update I wouldn't know.

Re: Dovecot 2.3.6 on Solaris10: build issues, segfaults
by Joseph Tam 23 Jul '19

23 Jul '19

Looking further into this segfault at settings-parser.c:setting_copy():1519 *dest_size = *src_size; *src_size points to type size_t (typedef unsigned long), a 4-byte aligned value consistent with a 32-bit build. This is mismatched with declared type (gdb) whatis src_size type = const uoff_t * (gdb) whatis uoff_t type = unsigned long long (gdb) p sizeof(uoff_t) $1 = 8 resulting in the segfault when *src_size is dereferened. The implied condition of this code segment is typeof(uoff_t)==typeof(size_t) which is clearly not the case. I'm not sure how/if uoff_t is defined, but configure reports checking for uoff_t... no checking type of off_t... long long The latter is weird, because if I compile and run using the same compiler flags #include <stdio.h> int main(void) { printf("%d %d\n",sizeof(long long),sizeof(off_t)); } the output is "8 4".

Dovecot with MySQL over SSL.

Hello! I'm attempting to get Dovecot working with MySQL user database on another machine. I can connect to the MySQL (5.7.26) instance with SSL enabled: mysql -h db.mrst.ee --ssl-ca=/etc/dovecot/ca.pem --ssl-cert=/etc/dovecot/client-cert.pem --ssl-key=/etc/dovecot/client-key.pem --ssl-cipher=DHE-RSA-AES256-SHA -u vmail -p However if I use the same values in dovecot-sql.conf.ext, I get the following error: Jul 19 00:20:18 turin dovecot: master: Dovecot v2.3.7 (494d20bdc) starting up for imap, lmtp, sieve (core dumps disabled) Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Database connection string: connect = host=db.mrst.ee dbname=vmail user=vmail password=stuff \ ssl_ca=/etc/dovecot/ca.pem \ ssl_cert=/etc/dovecot/client-cert.pem \ ssl_key=/etc/dovecot/client-key.pem \ ssl_cipher=DHE-RSA-AES256-SHA If I leave the ssl_cipher unset, I get: Jul 19 00:23:41 turin dovecot: auth-worker(83069): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: Failed to set ciphers to use - waiting for 1 seconds before retry Any ideas?
