Configuring Mail Clients

Here are details on how to set up some common email clients with the Bytemark Virtual Host Mail service.

Is your favourite client not listed and requires more than the information below? Then raise a ticket.

Generic Information applicable to all mail clients

The following details might be needed when setting up a mail client to use an email account. The user of alice@example.com on the machine example.vm.bytemark.co.uk has been chosen for these worked examples.

NB By default a self-signed certificate is used during the secure transactions. Some mail clients may warn you about this certificate being invalid. If you are at all unsure about the validity of the certificate is would be prudent to double-check it.

Incoming Email settings

Secure IMAP

  • Username: alice@example.com
  • Password: (contents of /srv/example.com/mailboxes/alice/password)
  • Server name: example.vm.bytemark.co.uk
  • Port number: 993
  • Use secure connection: SSL

Alternatively you can use:

  • Port number: 143
  • Use secure connection: TLS

To use IMAP without encryption, use port 143, and make sure any encryption settings are unchecked.

Secure POP3

  • Username: alice@example.com
  • Password: (contents of /srv/example.com/mailboxes/alice/password)
  • Server name: example.vm.bytemark.co.uk
  • Port number: 995
  • Use secure connection: SSL

Alternatively you can use:

  • Port number: 110
  • Use secure connection: TLS

To use POP3 without encryption, use port 110, and make sure any encryption settings are unchecked.

Outgoing (SMTP) Email

  • Username: alice@example.com
  • Password: (contents of /srv/example.com/mailboxes/alice/password)
  • Server name: example.vm.bytemark.co.uk
  • Port number: 465
  • Use secure connection: SSL

Alternatively you can use:

  • Port number: 25 (or 587 -- see below)
  • Use secure connection: TLS

If your ISP blocks port 25, i.e. you cannot connect at all to your machine with the standard SMTP port, then port 587 is provided as an alternative.

It is possible to relay mail without a secure connection on ports 25 and 587 -- just make sure that any secure connection boxes are left unchecked.
