Heartbleed openssl vulnerability?
Do we know if dovecot is vulnerable to the heartbleed SSL problem?
I'm running dovecot-2.0.9 and openssl-1.01, the latter being
intrinsically vulnerable. An on-line tool says that my machine is not
affected on port 993 but it would be nice to know for sure if we were
vulnerable for a while. (Naturally I've blocked it anyway!).
Thanks

ssl certificate, maximum protection, on the budget?
Hello,
I've got a client who wants to go ssl. He's running a web server,
smtp/pop, and ftps and imaps is coming as well. I'm looking for a wildcard
ssl certificate i believe it's called but one on the budget plan. I am also
wanting to ensure that the mod_ssl with httpd on the server is only using
the strongest encryption methods and protocols.
Thanks.
Dave.

Debugging Samba 4 AD Setup
We're using quite successfully a samba 4.1 AD setup authenticating user.
We have on an unregular basis
mails that can't be delivered because dovecot-pam fails to verify the
credentials. I'm trying to debug
this and set the loglevel up to 3.
I can see an error message being spammed in the log files and can't
figure out what causes this. I expect a configuration error somewhere

OpenSSL
Hello anyone used OpenSSL before?
Why do we need to pay for expensive SSL certs when there is OpenSSL
which is provided free? Is there a difference?
I''ve got an ecommerce website, and wondering if OpenSSL is enough?
Your thoughts will be appreciated

And sometimes dovecot create the directory and store the reply 's mail...

Hello,
I've been trying to figure this out for some time and can't quite nail it
down, despite searching the internet, and a couple of samba books. Here

Aw: Re: problem with lda
thanks for your input.
Bill: deliver is just a symlink to dovecot-lda
Stephan: I don't know, and and it even does not work when I use deliver -f "postmaster at ourdomain.internal" - I get the same error message.
A part of the mail I got when using 2.2.23:
Return-Path: <MAILER-DAEMON>

LDAP users/groups not showing up with nis, pam, & ldap
I am trying to configure NIS, PAM, & LDAP on a CentOS 6.2 host. I've
previously installed a similar configuration on RHEL4, but CentOS now
uses nss-pam-ldapd and nslcd instead of nss_ldap, so the configurations
are a little different.
Currently, local users and groups are showing up but not LDAP users.
When I do a /getent passwd/ and/getent group/ I don't get LDAP users.

problem with lda
Hello,
I am currently testing the upgrade from our dovecot v2.2.23 to 2.3.0. I have a strange problem with lda.
We use bounce mails for internal users if they try to send virus/spammails. The exact same config works with 2.2.23, but not with 2.3.0.

This is still happening after a reboot, Fedora 28. Restarting dovecot fixes
