[Dovecot] Can't start dovecot from heartbeat
by John Gray 01 Dec '09

01 Dec '09

I get the following error: Fatal: epoll_create(): Too many open files (you may need to increase /proc/sys/fs/epoll/max_user_instances) Works fine if I start it by hand, I'm guessing it has to due with the environment heart starts it in? My first thought was to do exactly what the message suggests, but my kernel doesn't appear to define max_user_instances, but there is a max_user_watches. I'm running 1.2.8, by the way. But I had a similar problem with earlier version too. John

Hi list I'm trying to get managesieve running (which seem to include the managesieve patches) on centos5, but compilation fails.

Hi everybody, I have a problem after configuring dovecot to work with mysql (Debian Etch System). When i send an email from outside, i have an undelivred mail returned to sender saying : Relay access denied (in reply to RCPT TO command) In my dovecot log file i have these errors : --------------------- Nov 28 20:08:27 myhost postfix/smtpd[5087]: connect from smtp5-g21.toto.com [1.2.3.4] Nov 28 20:08:27 myhost postfix/smtpd[5087]: NOQUEUE: reject: RCPT from smtp5-g21.toto.com [1.2.3.4]: 554 5.7.1 <mymail(a)test.com>: Relay access denied; from=<outside-mail(a)toto.com> to=<mymail(a)test.com> proto=ESMTP helo=<smtp5-g21.toto.com> Nov 28 20:08:28 myhost postfix/smtpd[5087]: disconnect from smtp5-g21.toto.com [1.2.3.4] ---------------------- What do you think is the problem ?

[Dovecot] Postfix issue but I want to fix it here...
by david＠davidwbrown.name 01 Dec '09

Hello, Dovecot bunch and Timo. I am using Sylpheed as my Dovecot/IMAP client. At home behind my LAN Sylpheed can send email because the Postfix SMTPd views my LAN as a trusted network. No such luck when I'm away from home. I know it has something to do with configuring the relay access elements but what I have tried so far does not work. I'm sure someone has had this simple issue previously. The error condition and other particulars follow: OS: CentOS, Windows XP SMTPd: Postfix 2.3.3 IMAP: Dovecot 1.2 Mail client: Sylpheed 2.7.1 Error condition: Error occurred while sending the message: 554 5.7.1 <messages-noreply(a)linkedin.com>: Relay access denied

[Dovecot] Dovecot SSL limitations
by Thomas Hummel 01 Dec '09

01 Dec '09

Hello Timo, I'd like to check if my understanding of dovecot-1.2.x's SSL certificate handling is correct : SSL does not provide the server any mechanism to choose which certificate it must send relatively to the name the client is using. Thus, if you want to use different certificates, you have to listen to different addresses. This is an SSL limitation, not a dovecot nor IMAP limitation. This is the reason why it's possible to use different certificates for IMAP and POP3. But it seems to work only with those two : As a matter of fact, even if you listen to different addresses, how would you tell dovecot to send this certificate for this address and that certificate for that address, since there is no IP dependent section (as in apache IP-based virtual host for instance) ? It seems the only way would be to have more than one instance of dovecot (several dovecot with different config files). The problem is that some clients may be configured with mail.my.domain, some others with imap.my.domain, ...etc... Hence the need to have different certificates with those different names as cn. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau
