How to get exim4’s smtp and pop3/imap server name and settings

configurationdebian-wheezyemailemail-serverexim

I'm missing exim4 configuration file in /etc/exim/exim4.conf.

dpkg-reconfigure exim4-config runs OK and sending/receiving emails is also OK. I just don't know where is the configuration saved.

The main thing is that I need to find out what to fill to Thunderbird's setup email fields (into smtp field and imap/pop3 field), because I cannot find the name of my smtp and imap/pop3 server. Where can I get it please?

EDIT: I've set mail.example.com when I was running configuration, but setting this to Thunderbird doesn't work.

EDIT2: In /etc/exim4/update-exim4.conf.conf I've found some configuration, but nothing about smtp/imap/pop3:

dc_eximconfig_configtype='internet'
dc_other_hostnames='example.com; localhost'
dc_local_interfaces='<MY_IP_ADDRESS> ; 127.0.0.1 ; ::1'
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname=''
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

Best Answer

You can access your server directly by IP address. The other possibility - is to use its domain name as far as all services are located on the same host. To find out connecting ports you have to use command ss | egrep "(exim|dovecot)" - you'll obtain the list of ports that services listen on. SSL/TLS is a bit more complicated, you have to perform mentioned above first.

Exim4 redirect mail sent to @domain1.example.com to @domain2.example.com

Please use example.com instead of domain2.com, example.com (and .org .net) was specifically created for examples and documentation.

In your /etc/exim4/update-exim4.conf.conf you have configured:

dc_use_split_config='false'

However you are changing something in /etc/exim4/conf.d/router/999_exim4-config_redirect which will be ignored because you are not using split configuration.

Either do:

dc_use_split_config='true'

And reload exim4, you may prefer to change it using:

dpkg-reconfigure exim4-config

Or edit /etc/exim4/exim4.conf.template to add your customisations instead and reload exim4 once done.

Debian exim4 has a feature called hubbed_hosts which can be a convenient way to accomplish what you want without having to add your own routers et al.

So if your want your server to send email destined for domain example.org to domain example.com which has MTAs listening on IPs 192.0.2.1 and 192.0.2.10 you do the following:

Create /etc/exim4/hubbed_hosts and add:

example.org: 192.0.2.1:192.0.2.10
reload exim4

Note, no spaces between the IP addresses and they're separated by a colon ':'

What this does is it will relay email destined for example.org to IPs 192.0.2.1,192.0.2.10 (in my example the IPs of example.com). It therefore will ignore the MX records of that domain. The IP address could be anything, as long as it is configured to receive those emails.

Finally there is address rewriting, see: http://www.exim.org/exim-html-current/doc/html/spec_html/ch31.html Perhaps it has something that will fit your requirements. You could use it in addition to hubbed_hosts.

Exim4 panic log: “Failed to get user name for uid 1001”

When exim queues a message, it stores lots of extra information with the message in the queue. One of the things that is stored with the message is the uid and gid that the process should run as. I'll bet if you grep your mail queue headers (probably in /var/spool/exim4/input/*-H) you will find those lingering 1001 and 1003 entries in the second line of some *-H files. I suggest your options are:

Delete those entries from the queue, or...
Stop exim. Manually edit those files changing the "uid gid" to match your new uid and gid. Start exim and see if it delivers properly.

It's also possible that there are some hard coded uid/gid's in the transport configurations? The actual exim configuration file in Debian is auto-generated from configuration settings, and its location can be displayed with exim -bV. The last line will be the location of the configuration file. Do some grepping and looking through that file to see if there is anything hard-coded.
