delay in receiving email

Erik Visser — Thu, 21 Aug 2025 00:00:00 +0200

FNWI users have been experiencing delays in email reception since early this morning.

We have been working on this issue but have not solved it yet.

No emails have been lost, but we suspect certificate issues between the Science mail servers and the central RU mail filter.

Update: the exact cause remains unknown.

During investigations together with RU-ILS, we noticed a long-standing Certificate Chain issue.

However, even after resolving this, the problem remained.

About Phishing via e-mail

Simon Oosthoek — Fri, 16 Dec 2022 00:00:00 +0100

Phishing

Trying to acquire useful data, ie login credentials, for abusing someone else’s ICT infrastructure.

Methods of phishing

In general, phishing works by send a clickable link surrounded by an important message about Salary, payment or a prize, a punishment or fee. This distracts your rational mind and ensures your emotional response controls your mouse-clicking finger.

Implementation Proofpoint for Science mail

Bjorn Bellink — Fri, 16 Dec 2022 00:00:00 +0100

Unfortunately, we have recently seen a strong increase in successful phishing attempts in the Science domain, a mailing about this issue was already sent last week.

At the same time, we worked hard in collaboration with ILS to also deploy the centrally used anti-phishing tooling from Proofpoint for FNWI. The central RU mail environment has been supplemented with this highly effective anti-phishing measure for some time now.

As soon as the Science mail domains are also placed ‘behind’ this anti-phishing tool, things will change for users who have not yet had to deal with this. More information can be found on https://www.ru.nl/ict/algemeen/proofpoint/.

Mailman lists

Mailing lists

Mailman lists are highly configurable and moderatable mailman mailing lists, e.g. the list of FNWI-employees or the list of FNWI-students. Usually one can add oneself to or remove oneself from such a mailman mailing list. Every mailman mailing list has a moderator, who can approve or reject messages to the mailman mailing list. For mailman list admins: To filter spam one can choose in the Privacy options... under Spam filters as Spam filter regexp:

Tip

Webmail

For quick access to your email, use our webmailer:

https://roundcube.science.ru.nl/

When Roundcube asks for an OTP code, use the one from the OTP app you enrolled in DIY.

Email settings

When setting up your e-mail programs, it is sufficient to only enter your e-mail address. This is what your Science email address looks like:

I.Lastname@science.ru.nl

All technical settings are then automatically filled in for you. If that does not work, or if it is necessary to fill in the details yourself, use the settings in the table below:

The RU MS365 instructions do not mention Thunderbird, but there is a RU created set of instructions (pictures in Dutch).

Email sieve

Wed, 27 Jun 2018 05:42:46 +0000

Sieve

If one wants incoming mail to be sorted into folders automatically or to be filtered in some special way, one can use “Sieve” if one has the IMAP-server post.science.ru.nl as incoming mailserver.
To put the sieve script on the mail server and activate it, use a mail program which supports sieve. The filter settings can be managed quite easily in Roundcube webmail with Settings -> Filters. It is also possible with e.g. KMail or Thunderbird with the sieve addon.
On lilo4 you get with the command sieve-connect postvak.science.ru.nl an interactive commandline where you can use the command put to upload a sieve script.
The Sieve language is described in RFC3028.

Email vakantie

Wed, 09 Apr 2008 22:19:36 +0000

Automatically respond to incoming email

The settings to automatically respond to incoming email can be changed at the Do-It-Yourself website.

If a (vacation) message is sent for incoming email, each sender of a mail that is directly sent to you (no BCC:), gets only once a mail with the text you have specified.

If one does not want to send automatic replies anymore, the (vacation) message is saved for later use.
