whenever I change dovecot config to use 993 IMAPS port instead of standard 143 IMAP, roundcube refuses to work with errormessage:
Connection to storage server failed.
Server Error: Could not connect to localhost:143: Connection refused
Port 143 is not responding since I disabled it and want to use 993 only.
But I can't get roundcube to use this port even though when I configre standardport for IMAP to 993 in "/etc/roundcube/defaults.inc.php":
$config['default_host'] = 'ssl://localhost';
// TCP port used for IMAP connections
$config['default_port'] = 993;
Dovecot version:
ii dovecot-core 1:2.2.27-3+deb9u1 amd64
ii dovecot-imapd 1:2.2.27-3+deb9u1 amd64
ii dovecot-managesieved 1:2.2.27-3+deb9u1 amd64
ii dovecot-sieve 1:2.2.27-3+deb9u1 amd64
Roundcube version:
ii roundcube 1.2.3+dfsg.1-4
ii roundcube-core 1.2.3+dfsg.1-4
ii roundcube-mysql 1.2.3+dfsg.1-4
ii roundcube-plugins 1.2.3+dfsg.1-4
ii roundcube-plugins-extra 1.2.1-20160803
Help would be appreciated.
It was an error within my settings. Because of the certificate u need use the proper hostname and not localhost.
$config['default_host'] = 'ssl://FQDNofhostname';
// TCP port used for IMAP connections
$config['default_port'] = 993;

MY PROBLEM is the ports 25,465 and 587 are coming up and then shutdown because of port already in use ,Can any one assist me to fix this problem?
When i save the config (/etc/mail/sendmail.mc) and restart sendmail ,port 465 seems to be used and shutdown the whole outgoing ports 25,465 and 587.
logs file have the below entries
daemon TLSMTA: problem creating SMTP socket
Feb 9 13:26:43 mail sm-mta[20646]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon TLSMTA: cannot bind: Address already in use

MY PROBLEM is the ports 25,465 and 587 are coming up and then shutdown because of port already in use ,Can any one assist me to fix this problem?
Short list to check...
1st) have You compiled sendmail.mc into sendmail.cf ?
2nd) TLSMTA: cannot bind: Address already in use... means that one process already use this port (smtps: 465),
- check who is using port (e.g. "netstat -lntp|grep 465")
- and stop this, sometimes port can be in use by connection, maybe instead restart You should: stop, wait few sec./minutes and then start sendmail
- "netstat -lntp|grep sendmail" can be usefull to see sendmail's listening ports
- before start be sure that ports are not occupied (not in use)
- problem may also be in SELINUX (investigate how to allow program to use ports)

I installed postfix on a server, but port 25 was blocked by ISP. I followed http://www.postfix.org/TLS_README.html#client_smtps to configure smtps on port 465.
I follow the configuration as Postfix ≥ 3.0: Sending only mail for a specific destination via SMTPS,
But I have to add mail domain to /etc/postfix/transport.
a.com relay-smtps:mx.a.com:465
b.com relay-smtps:mx.b.com:465
part of /etc/postfix/main.cf:
smtp_tls_session_cache_database = btree:/var/lib/postfix/smtp_scache
smtp_tls_security_level = may
tls_random_source = dev:/dev/urandom
smtp_tls_loglevel = 1
transport_maps = hash:/etc/postfix/transport
part of /etc/postfix/master.cf:
relay-smtps unix - - n - - smtp
# Client-side SMTPS requires "encrypt" or stronger.
-o smtp_tls_security_level=encrypt
-o smtp_tls_wrappermode=yes
For destination not in transport, postfix tries connect to port 25.
I can only send email to destination listed in transport.
How do I change the postfix so that it tries send all emails to [their own DNS MX record]:465 ?
I have tried Postfix ≥ 3.0: Sending all remote mail to an SMTPS server:
relayhost = [mx.a.com]:465
But it was regarded as spam.
If I do like:
mydomain.com :
* relay-smtps:how can use DNS MX recode auto:465
How can I specify port 465 and use DNS MX record?
Thanks!
My Net::SMTP code on Windows 2012 / StrawberryPerl is crapping out and I think it's because Perl is trying to use IPv6 addresses and my local MS SMTP server isn't running on IPv6. The following works, but if I use "localhost" or the FQDN the Net::SMTP->new() fails and $# contains "Bad address"
my $smtp = Net::SMTP->new('127.0.0.1',
Timeout => 30,
Debug => 1,
);
Also, if I use the FQDN of a remote SMTP server (Windows 2008 / IMail), it works.
Both the local & remote servers have SMTP listening on port 25 only for IPv4.
Is there a way to force IPv4 within my script? I thought about disabling IPv6 within Windows but I read that it isn't recommended. What else can I try to debug this?
You can try forcing the dns resolution to ipv4 with Domain => AF_INET}, i.e.:
my $smtp = Net::SMTP->new('FQDN',
Timeout => 30,
Domain => AF_INET,
Debug => 1,
);
If "Domain" is not given, AF_UNSPEC is assumed, that is, both AF_INET
and AF_INET6 will be both considered when resolving DNS names.
AF_INET6 is prioritary.

I recently installed Postfix, Dovecot to setup a mail server on my own VPS ( using this tutorial: Email with Postfix, Dovecot, Mysql)
Imaps server uses port 993 for Authentication, and Postfix uses port 25 to send mails.
In this tutorial, users stored in a Database ( so imaps use mysql to authenticate users).
i'm sure every thing works fine with imaps and postfix , because few days ago i installed Kmail client (on my linux) and receive mails from my server. sending mails also works fine, i sent a mail to Gmail and google received it without a problem (in my "Gmail inbox" not spam folder)
So to get to my Emails from a web mail client, i installed Roundcube on /var/www/mail directory.
I configured Roundcube many times. but each time it gives me this Error:
IMAP Error: Login failed for [me#mydomain] from X.x.X.x . Empty
startup greeting (localhost:993) in
/var/www/mm/program/lib/Roundcube/rcube_imap.php on line 184 (POST
/mm/?_task=login?_task=login&_action=login)
When i do log in from roundcube, imap server says ( in /var/log/mail.log ):
May 20 07:05:16 my-server dovecot: imap-login: Disconnected (no auth
attempts): rip=::1, lip=::1, TLS handshaking: Disconnected
Here is my roundcube config file :
$config['db_dsnw'] = 'mysql://roundcubeuser:myPassword#localhost/roundcubemail';
// ----------------------------------
// IMAP
// ----------------------------------
$config['debug_level'] = 13;
$config['default_host'] = 'ssl://127.0.0.1';
$config['default_port'] = 993;
// ----------------------------------
// SMTP
// ----------------------------------
$config['smtp_server'] = 'ssl://localhost';
What's the problem? i really have no idea what is happening !
Thank you.
I'm using postfix + dovecot + roundcube a few months now and it's working for me. In my configuration, postfix rejects plaintext sessions, so roundcube has to connect with ssl - and it's working.
This is from my main.inc.php. I don't remember editing anything here, it's just the initial config created during the installation.
Now that I'm looking at it, default_port doesn't make any sense, I think it's just ignored.
// To use SSL/TLS connection, enter hostname with prefix ssl:// or tls://
// Supported replacement variables:
// %n - http hostname ($_SERVER['SERVER_NAME'])
// %d - domain (http hostname without the first part)
// %s - domain name after the '#' from e-mail address provided at login screen
// For example %n = mail.domain.tld, %d = domain.tld
// TCP port used for IMAP connections
$rcmail_config['default_port'] = 143;
$rcmail_config['default_host'] = array("ssl://localhost:993");
// TCP port used for IMAP connections
$rcmail_config['default_port'] = 143;
In case the other answer does not work, this is what worked for me. My config.inc.php now contains:
$config['default_host'] = 'ssl://localhost';
$config['default_port'] = 993;
NOTE: using tls://localhost did not work for me. I had to specify ssl:// as the URI scheme.
Via PhpMyAdmin, I also ran this SQL command (all my user accounts are on the same machine that runs RoundCube):
UPDATE `rc_users` SET `mail_host`='ssl://localhost'
I got the port number 993 from running sudo netstat -tulnp in order to determine the port on which Dovecot was listening.
hi i am using smack.jar to connect to my gmail server. but xmppconnection.connet() is failing and it says that server is not responding . i am attaching the log. please help me out.

To be clear, the server isn't returning this error, because you haven't connected to the server yet.
It might be a configuration problem. If your server doesn't have a client DNS SRV record (e.g. _xmpp-client._tcp.gmail.com), then you'll need to pass the XMPPConnection object a ConnectionConfiguration with the name of the machine to connect to for your domain.
It is also possible that this is a network problem (connectivity, routing, firewall, etc.). To test for this, try commands like this on the command line:
% dig +short _xmpp-client._tcp.gmail.com SRV
5 0 5222 talk.l.google.com.
20 0 5222 talk2.l.google.com.
20 0 5222 talk1.l.google.com.
20 0 5222 talk3.l.google.com.
20 0 5222 talk4.l.google.com.
% telnet talk.l.google.com 5222
Trying 74.125.155.125...
Connected to talk.l.google.com.
Escape character is '^]'.
>
Note that you type the greater-than character. Most XMPP servers will disconnect you immediately at this point, since you've sent them XML that is not well-formed.
If you've got a network problem, you'll see something like this:
Trying 74.125.155.125...
telnet: connect to address 74.125.155.125: Connection refused
telnet: Unable to connect to remote host
