VPOP3 Configuration

Change mail server name

A mail server publishes its 'name' in several ways: * when sending a HELO or EHLO command to a remote mail server, it will say something like _EHLO mail.server.name_ * when an SMTP client connects to it, it will say something like _220 mail.server.name SMTP server ready_ The mail server name should, ideally, be the DNS name of the mail server because some other mail servers will check this. To change the server name in VPOP3, go to Settings -> Misc Settings -> General_ _and set...

Should any disk folders on the VPOP3 server be shared?

VPOP3 supplies email to client computers using protocols such as IMAP4, POP3, etc, so you do not need to share folders on the VPOP3 server at all. In general it is best NOT to share the folders, because that way users cannot cause damage to the VPOP3 configuration, and viruses on users computers cannot affect VPOP3's files.

Adding IMAP4 SSL service support using STUNNEL

All editions of VPOP3 (from v3 onwards) support SSL connections to remote mail servers. To use these, just enable the relevant encryption options in the Mail Connectors, and change the 'port' number if appropriate. VPOP3 Enterprise supports SSL or STARTTLS (TLS) connections from email clients to VPOP3. To use these you will need an SSL certificate. There are instructions for this on our wiki (https://wiki.pscs.co.uk/how_to:encrypt_sessions). The one limitation currently in VPOP3 is that the IM...

DNS Servers for internal and external access to VPOP3

If you want to be able to use your VPOP3 server on devices (e.g. phones & tablets) when they are connected to your office Wifi and also when they are outside the office, you need to be able to configure them so that they can access your VPOP3 server wherever they are. If your router supports NAT loopback (or NAT reflection), then you can simply use the external IP address, and you'll be able to access it from inside the office as well, however this can be slow with some routers so it is not alw...

Allow remote access to VPOP3 mailboxes (v6.0 or later)

Sometimes people want to be able to access their office VPOP3 mail server from a remote site or mobile phone etc. These instructions assume you have a permanent Internet connection (eg ADSL, Cable etc). If you don't have a permanent Internet connection, see here (https://wiki.pscs.co.uk/how_to:remoteaccessdialup) **Router/Firewall Configuration** First you need to set your router and/or firewall to allow incoming access to the VPOP3 computer on the relevant ports (eg 110 for POP3, 143 for ...
