customizing Asterisk CLI
Hello,
when I am in the Asterisk CLI, I can exit with 'exit' or 'quit'. Ctrl+d
has no effect. Is there any way to "bind" Ctrl+d to exit/quit ?
Also, when I am in asterisk CLI, I can use command history and readline
functions such as CTRL+r to search. But not all functions are available.
For example, the alternate mappings for "page up" and "page

Calendar and address book with Dovecot
Hi all
I recently install Postfix and Dovecot, and so far so good. My assumption
was that calendar and address book (similar to Gmail calendar or address
book) are part of Dovecot. However I do not see anything concerning them in
any of the docs I have read so far.
What other software (ideally open source, free) do I need in other to have

Sieve: adding Date: header when missing
Hello,
there is a way with a sieve rule to add a Date: header when it is
missing? Adding one with the time of reception of the message or using
the date from the the first Received: header would be good options.
Unfortunately I'm receiving some useful automated messages that lack a
Date header and this screws up the sorting in my imap clients. I have a
script to fix those acting on the

IMAP on 993/SSL or 143/STARTTLS?
Hi,
I have a postfix+dovecot-2.2.13 system and have configured it to support
IMAPS on 993 with SSL/TLS. I'm noticing with users using Thunderbird, the
autodetect defaults to IMAPS on 143 with STARTTLS.
Which is preferred? Which is more secure? Which is more common?
Why would someone choose one over the other?
Can I ask the same question about SMTP and submission? Why would one choose

/etc/ssl/certs/dovecot.pem erased by OpenSuse's update mechanism
Why not /etc/dovecot/private? That's where I put my dovecot certs. Dovecot's needs are a bit different from other software, and so it is unclear whether the files won't be unique to it. For example, I haven't seen the following before I read it on the Dovecot wiki:
"The CA file should contain the certificate(s) followed by the matching CRL(s). Note that the CRLs are required

Sometimes I have this in the logfile:

RFE: dnsbl-support for dovecot
after having my own dnsbl feeded by a honeypot and even
mod_security supports it for webservers i think dovecot
sould support the same to prevent dictionary attacks from
known bad hosts, in our case that blacklist is 100%
trustable and blocks before SMTP-Auth while normal RBL's
are after SASL
i admit that i am not a C/C++-programmer, but i think

controlling STARTTLS by IP address

Yes, of course. But that would require multiple ports, making the client
configuration cumbersome and error-prone.

Broken IMAPS Connects Create Lingering imap-login Processes
Hello everyone,
we are running a central server (CentOS 6.5, dovecot-2.0.9-7.el6 with a
small patch to disable the IMAP CREATE command, and
openssl-1.0.1e-16.el6_5.7) and distribute standard client software to
customer( site)s.
The clients do IMAPS connects in regular intervals (no IDLE, no
lingering logins) and authenticate with certs issued by a dedicated PKI

I wonder if there is an easy way to provide dovecot a flat text file of
ipv4 #'s which should be ignored or dropped?
I have accumulated 45,000+ IPs which routinely try dictionary and
12345678 password attempts. The file is too big to create firewall
drops, and I don't want to compile with wrappers *if* dovecot has an
easy ability to do this. If dovecot could parse a flat text file of

TLS not working with iOS beta?
Hi,
Have anyone else experienced problems using Dovecot with the mail app in beta releases of iOS/iPadOS 13?
TLS is failing for my, it have worked fine for years and I am on the latest Dovecot version now, it works fine with older clients but not with the ones upgraded:
