Hi I have "problem" with dovect 2.2.13 from repo debian8 and I don't know how to solve it ... Server is a virtual (kvm) with debian 8.11 (postfix + dovecot from repo) and storage is mounting via nfs (I have use only one dovecot with external storage) All works fine but sometime ( after a few hours ) I have got a problem with dovecot cache (i use indexes) logs -> http://paste.debian.net/1117072/ The store is mounted via nfs in /home/ index is local in /var/dovecot_indexes%h All go back to normal when i remove indexes like: find /var/dovecot_indexes/home/ -name 'dovecot*' -type f -delete but this is not good solution What am I doing wrong ?

Hello, I have 2 Dovecot 2.3.8 servers running SSL with valid wildcard certificates. Email clients connect fine, https://www.immuniweb.com/ssl/ tests show certificates are ok. However I can't make replication work when I add ssl = yes. Without ssl it works ok. I added verbose_ssl in config and error log shows: dovecot: doveadm(149.x.x.x): Error: SSL handshake failed: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol >From the other server 149.x.x.x I tested with openssl: openssl s_client -connect 188.x.x.x:12333 -crlf -CAfile /etc/pki/tls/cert.pem CONNECTED(00000003) depth=2 C = US, ST = New Jersey, L = Jersey City, O = The USERTRUST Network, CN = USERTrust RSA Certification Authority verify return:1 depth=1 C = GB, ST = Greater Manchester, L = Salford, O = Sectigo Limited, CN = Sectigo RSA Organization Validation Secure Server CA verify return:1 depth=0 C = FR, postalCode = 34980, ST = Occitanie, L = Montpellier, street = 123 Main str, O = My Company, OU = PremiumSSL Wildcard, CN = *.domain.com verify return:1 . .

Sieve and recipient_delimiter
by ＠lbutlr 17 Nov '19

17 Nov '19

I use recipient_delimiter addresseses quiet a bit, and I want to put several of them into a mailbox if anyof (header :contains ["to"] [ “FOO", “foo", “bar", “florin"]) { fileinto :create “later"; stop; } When I get an email addressed to me+FOO(a)example.com or me_florin(a)example.com, the messages end up in my inbox (Yes, I have both + and _ defined as delimiters in postfix and in dovecot). Is this because sieve is not seeing the delimiter? I am wondering this because I have another rule that seems to be working fine that is largely the same, but operates on domains: if anyof ( header :contains ["From"] [“kreme.com", “localdomain1.tld”, "localdomain2.tld", "localdomain3.tld", “covisp.net” ]){ fileinto :create "priority"; } -- She'd always tried to face towards the light.

Auto expunge log

Hi, I'm just setting up a new dovecot system and wonder why I get this error. On another dovecot system this works with no problems.

I believe there should be a "Mailbox" in between? Configuration in /etc/dovecot/conf.d/15-mailboxed.conf =========================== namespace inbox { mailbox Junk { auto = subscribe special_use = \Junk autoexpunge = 90d } =========================== Maybe you can help me a bit. ;-) Michael

Feature request: ssl-cert config
by Marc Roos 16 Nov '19

16 Nov '19

I am not sure why this </ is used in the configuration. But I hoped it would concatenate the ssl_cert to have multiple certificates. So one could use it multiple times, as needed. It would be nice to be able to specify the intermediate certificate (bundle) separate from the certificate, so when updating the certificate I just have to replace this file. Something like local_name mail.xxxxxx.xxx { ssl_key = </etc/pki/tls/private/mail.xxxxxx.xxx.key ssl_cert = </etc/pki/tls/certs/mail.xxxxxx.xxx.crt ssl_cert = </etc/pki/tls/certs/SectigoIntermediate.crt } Or local_name mail.xxxxxx.xxx { ssl_key = </etc/pki/tls/private/mail.xxxxxx.xxx.key ssl_cert = </etc/pki/tls/certs/mail.xxxxxx.xxx.crt ssl_int = </etc/pki/tls/certs/SectigoIntermediate.crt } dovecot-2.2.36-3.el7_7.1.x86_64
