two lots of dovecot files
by mick crane 04 Mar '19

hello is debian buster I have 2 sets of dovecot files, I don't know why. one in /etc/dovecot and one in /usr/share/dovecot they are not links they are actual files. if I rename /etc/dovecot and restart service then I get connection refused when use roundcube. Some time ago my roundcube installation stopped working properly for the web configuration options. Should I have these 2 directories or just want the one ? If want only one it's likely then that I configure wrong file with same name when I thought my ssl certificate has expired. Is OK to delete /etc/dovecot and check configuration in /usr/share/dovecot ? -- Key ID C7D6E24C

Pigeonhome Sieve: check existence of a folder?
by AvV 03 Mar '19

Dear All, Thanks ofr the great job so far. I have crawled the doc & web, and did not find oh to check for the presence of a folder ina a mailbox? I know about "fileinto :create" of course, but the purpose is slightly different: I want to automate the move into a folder based on some rules but *only if* an associated folder is present (which name is based on the rule), otherwise I will do a form of catch-all. Example: - INBOX +- abc +- def - Rule detects "aaa" in someheader field: folder "aaa" not present" -> continue; - Rule detect "def" in some header field: "def exists" -> fileinto "def" ; stop; Any help appreciated. Cheers, A/

I have 2.2 installation on Centos 7, and, I'm trying to setup a new server, and, 'clone' existing setup: Dovecot/Postfix/Mysql on new Centos 7 installed from RPM 2.3.4.1 (3c0b8769e) I then copied/overwrote from old to new /etc/dovecot/*.conf (but not conf.d files), created self certs in place of old server certs and, started Dovecot is that totally dumb, and, how should I do this, or ? upon starting dovecot and, trying to access mailbox from K9 client I see in the log [1]: what's my best way forward with this ?

Unexpected behavior with sieve_vacation_to_header_ignore_envelope = yes
by Matthias Petermann 03 Mar '19

03 Mar '19

Hello, we face an issue with the vacation extension of pigeonhole. Our upstream mail server (from which we pull our E-Mails with POP3) uses SPF and performs a SRS re-write of the Return Path. Once the mail is processed via our local postfix, it is delivered via dovecot deliver (using the lda). When the recipient has a vacation rule enabled in sieve, the out-of-office note cannot be sent, as pigeonhole tries to use the Return-Path (which is not accepted as sender by the mail server). We are using the following dovecot / pigeonhole versions: dovecot-2.3.2.1 dovecot-pigeonhole-0.5.2 As of my understanding, the problem was addressed in pigeonhole version v0.4.21 by introducing the sieve_vacation_to_header_ignore_envelope setting. Anyway - even when this is set to "yes" pigeonhole still uses the Return-Path instead of the "From:" header which I had expected: Feb 27 13:22:26 mail dovecot: lda(customer)<48383><3o+yOQGBdlz/vAAAZU03Dg>: Error: sieve: msgid=<e081d2ba-21d5-c32b-3750-69fe0c8a76d2(a)petermann-it.de>: failed to send vacation response to SRS0=gwGXg6ad=RC=petermann-it.de=matthias(a)example.com: <Sendmail program returned error> (temporary error) Are my expectations wrong or did I miss some precondition?

same account imap and pop3
by James 02 Mar '19

02 Mar '19

I have an imap and pop3 for the same account. When I delete a message from imap and then fetch the mail from the pop3 account, it retrieves the deleted message. I am using thunderbird for the MTA. Does anyone know why it happens? It could be a timing issue.
