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".

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?

Pure-FTPd’s SNI daemon
by Felipe Gasper 22 Jul '19

22 Jul '19

Hello, Pure-FTPd just adopted an interesting approach to SNI support: a separate daemon that serves cert chain and key for a given hostname. What would be involved in having Dovecot support this daemon? It would alleviate the need right now for a very large “sni.conf” file on hosts that serve thousands of domains. Thank you! -Felipe Gasper Mississauga, ON

22 Jul '19

Hi Timo I have a strange question. I bought the Dovecot Book off Amazon. I can easily prove it with a picture and/or my receipt off Amazon. I still have it o my library but I don’t like to travel around with it. Is there a way for me to get a PDF copy? I just checked Amazon and there is still no PDF version available there.

22 Jul '19

Hi everybody, after an update this morning to dovecot 2.3.7 we cannot connect to our shared mailboxes anymore. The error message as issued in Thunderbird: "Character not allowed in mailbox name '.'" I didn't change anything about the configuration. Output of dovecot -n: [...] namespace { list = children location = maildir:%%h:INDEX=%h/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = yes type = shared } [...] Any help would be appreciated, thank you very much.
