Hi, I am running a dovecot server and have set up an external monitoring, where every five minutes a login with SSL on port 993 is done. I usually get once a day an error "connection reset by peer - SSL connect", which goes away until the next monitor is executed. Initially I thought that raising the mail_max_userip_connections in protocol imap in 20-imap.conf to 256 should do the

I am use to low random entropy on my arm boards, not an intel. On my Lenovo x120e, cat /proc/sys/kernel/random/entropy_avail reports 3190 bits of entropy. On my armv7 with Centos7 I would get 130 unless I installed rng-tools and then I get ~1300. SSH into one and it drops back to 30! for a few minutes. Sigh. Anyway on my new Zotac nano ad12 with an AMD E-1800 duo core, I am seeing 180.

Hello list we encounter a weird SSL issue with one of our dovecot (2.2.24 on Centos6) which we can only explain if our assumtion is correct Symptoms are that imaps connections (on port 993) suddenly get veeeery slow. Up to 180s for one connection with openssl s_client The thing we do not understand is that in the same time imap connections with starttls are just 1s. We can see that entropy on the

Hi, I have error log entries like dovecot: lmtp(22155, mail): Error: user mail: Mail access for users with UID 8 not permitted (see first_valid_uid in config file, uid from userdb lookup). This obviously tells me that the user mail (UID 8) is trying to access the LMTP daemon. How can I find out why he is doing so and how I can get rid of this error message? The mail system (Ubuntu 14.04 LTS :

Hello. I'm a distro maintainer and was wondering about the efficacy of entropy daemons like haveged and jitterentropyd in qemu-kvm. One of the authors of haveged [0] pointed out if the hardware cycles counter is emulated and deterministic, and thus predictible. He therefore does not recommend using HAVEGE on those systems. Is this the case with KVM's counters? PS. I will be setting VM CPU

This problem came about when I noticed exim, on a domU, holding mail in its queue for days before delivering. After a bit of debugging then I found gnutls was taking ages to calculate its keys. So disabled TLS in exim and works fine. Then I had another xen domU doing exactly the same thing so I did some more digging and came up with this post:

Hello When booting from a slow machine, I can observe dovecot blocking the whole boot process. I traced it down to the getrandom() system call in lib/randgen.c, which blocks until the random number generator is initialized (dmesg "random: crng init done"). This can take up to three minutes (!) on my machine, as there is not much entropy available (no hardware RNG, network VPN is also
