Cheers Remko and Ralph. I think there was some mention in the lets encrypt FAQ that certbot doesn't do email. But I understand I can use their generated very for dovecot, postfix and https? That would be good indeed. Anyone know of any manual, or can I just replace the certs in the dovecot and postfix locations with theirs? Do dovecot, postfix and apache all support .pem format?

So I generated a new certificate for dovecot, and ever since I have this weird problem that my iPhone can still receive mail but cannot send using that mailserver. Same for my iMac. My laptop works fine still and can do both. Local issue you would say right. I'm wondering if there is any cache for a certificate or something, my maillog shows up something like 10 bytes read, -1. So it returns

Thanks Ralph, i?ll look into that. I think let?s encrypt uses certbot though and it can?t do email certificates (although i?m sure i can convert the cert i get from let?s encrypt, i?ll look into it. > On 9 Aug 2017, at 16:40, Ralph Seichter <m16+dovecot at monksofcool.net> wrote: > > On 09.08.2017 17:20, Alef Veld wrote: > >> So i?m using dovecot, and i created a self

No added benefit to have your certificate certified by a third party, why would they care

Hi all. I?m a bit worried about the following read errors i see in my log lately. Mails still arrive and get sent fine, but what is going on with this? It doesn?t look good. Nothing has change on server side and i restarted all services (dovecot, postfix, saslauthd, sql ). Maybe it?s a temporary iPhone thing (the device im using to read and send mails, not the first time that happened. Maybe

So i?m using dovecot, and i created a self signed certificate with mkcert.sh based on dovecot-openssl.cnf. The name in there matches my mail server. The first time it connects in mac mail however, it says the certificate is invalid and another server might pretend to be me etc. I then have the option of trusting it. Is this normal behaviour? Will it always be invalid if it?s not signed by a

Hi everyone. Nice to meet you. I?m new to dovecot and i came across a problem it seems. I setup a new user called sales with useradd, and gave it a password. Although it has a home directory, i set login to /sbin/nologin. When logging into the pop server on port 110 (with telnet) i get this in the logs: dovecot: pop3-login: Login: user=<sales>, method=PLAIN, rip=127.0.0.1,

Hi, I?m facing here a wierd problem: We have a vacation messaging system using sieve. When activated the system forwards incomming messages to a given address and sents an out of office reply to the sender. This works like a charm when the mail is addressed to mailbox at domain. When the incomming mail ist addressed to alias.to.mailbox at domain the mail is delivered to the mailbox, it is

Dear list, I?m running a postfix (2.5.6) / Dovecot (1.1.11) on a Centos 5.2 box. I?ve written a small gui application to simply create Out of Office replys with sieve. The resulting code did work with maildrop without any problems. Now sieve fails when it meets any german umlauts like ? or ?. It just stops compiling the scripts and complains about the missing "};". A simple fix is

Hi folks. I've recently set up a Postfix 2.9.6/Dovecot 2.0.19 IMAPS/SMTPS setup on Ubuntu 12.04.2 (Mysql backend). I'm new to all this, so I apologize if this is fairly basic. I've attempted to the best of my ability to search for an answer, but no luck so far. What I'm trying to do is generate a password hash that I can inject directly into my Mysql database (disaster recovery

I can't see any security advantages of a self signed cert. If the keypair is generated locally (which it should) a certificate signed by an external CA can't be worse just by the additional signature of the external CA. Better security can only be gained if all users are urged to remove all preinstalled trusted CAs from their mail clients (which seems impractical). Else an attacker could

Hi All! I only ever have complex setups. Customer site has a dedicated leased line from their ISP terminating on a Cisco router. Router is configuered with the first usable address on a /28 network - 196.x.y.73. The linux firewall is configured with the remaining 5 ip''s, 196.x.y.74 to 196.x.y.78 and 79 as the broadcast. Sounds normal but here is the twist. The primary or first ip

I'm using postfix smtpd / dovecot. Running imaps, imap, pop3s, pop3. I have a ssl certificate setup. Everything works fine via IMAP except sending to an email from outside the network to a recipient outside the network. The problem is when someone (and this is being tested thru the iphone email client configured to use imap) logs in, they can read messages but cannot send to an address
