What about email filters, like my old .forward file?

Filters are created in Roundcube, the webmail interface.  In the past you may have written filters in plain text files, maybe a .forward or a .procmailrc file.  Unfortunately there is no way to reuse these old filters and import them into Roundcube.  Roundcube's filters are written in 'sieve'.  The interface is more graphical than old formats.  You can find the filter section by logging into Roundcube, on the left of the window there is the cog wheel settings icon, click it.  Under the 'Settings' menu select ''Filters'.  You can then create a filter by clicking on another cog wheel icon to the right of the 'Settings' menu, the cog icon is labelled 'Actions'.  Please bear in mind that with different version of Roundcube these menus may change layout and labels.

If you used to use .forward or .procmailrc files then you will need to manually convert them into sieve.  To speed this process up read through your old filters and work out what is still applicable and focus on moving just those.

There are a number of webpages to help guide you through the Roundcube filter interface, it's reasonably intuitive, but help can be found at:

What is 'plus' + addressing and how is it used?

Plus addressing means any email sent to is still sent to your account. This means you can have a lot of variations on your email address to give out to different people, sites, or mailing lists. 

When the email server receives such an email it can automatically save it into a folder as specified after the + in the email address.  NOTE this is case sensitive.

E.g. you tell people to use the address, email sent to that address will be delivered into your folder called Wellbeing (create the folder first, note the capital 'W').

  • Ensure the folder already exists otherwise the mail will just go into the inbox as usual
  • The folder name is case sensitive

If the folder already exists then the mail will be automatically saved there; otherwise the mail will go into the inbox as usual

Set up spam score

Log into Roundcube

  • Click on the cog looking icon labelled settings on the left of the screen.
  • To create the filter, click on the text 'Filters'
  • To create a new filter click on the word 'Create' (it has a '+'  icon) at the top right of the window
  • Give the filter a name
  • Change 'Scope' to 'matching any of the following rules'
  • From the drop down menu underneath the word 'Rules', select 'X-cam-SpamScore'
  • From the drop down to the right of 'X-cam-SpamScore' select 'contains'
  • To the right of this drop down type in 'sssss'
  • Change the drop down below the word 'Rules' to 'move message to'
  • Select the folder you wish to move spam to

Is my mail backed up?

Yes. Backups are kept for 30 days; account deletions are kept for 6 months (after a person leaves)

What rate-limits apply to the Maths mail service?

In order to prevent misuse (especially to protect against spammers), the faculty mail servers enforce the following limits:

1000 recipients, per hour, per person/machine.

This is further limited while the connection is made from outside the faculty network (excluding vpn, hotdesk, webmail, etc...):

250 recipients, per hour, per authenticated user.

If you are required to send bulk-email then we strongly advise the use of a mailing list.

Can I get to my address book from the old webmail?

Prayer (the old webmail system) stores the address book as a message in IMAP - thus it can be accessed from most mail clients. A simple method is to use the new webmail to access it:

I have email in zipped files (.bz2), will these files move?

These will be unzipped for you and moved to the new mail server.

Can I still use or or (and respective smtp server settings)?

No, change imap server address to and smtp server to

When my email has moved to the new email server will it read email from my /mail folder in my home directory?

Short answer is no, all mail is stored on the server.  You can keep your /mail folder for reference but the new mail server will not read or write to it, it's how it works.

We have instructions on how to configure Pine (now called AlPine) to read folders on the new mail server.

My email was moved to the new Maths server and now my Mac says 'logins are disabled", how do I fix this?

The setting SSL needs to be switch on to fix this error.
