+[[https://www.mailjet.com/|Mailjet]] is an SMTP relay which we use for transactional emails, for applications like [[applications:vaultwarden|Vaultwarden]]. It is properly set up for sending mail from ''@cssbham.com'' addresses.
+Having a trusted sender like Mailjet to send mail is necessary as the University's mail service is very strict with external senders. In my (Leonardo's) experience I get blocked after about 5 or so messages trying to send mail without a relay. Unfortunately, it does not seem like there is an easy way to get SMTP connection information for the Guild webmail, so we can't use our Guild address for transactional mail.
 The credentials are stored in Vaultwarden.
+===== Limits =====
+At time of writing, the free tier permits 6,000 messages a month, at a rate of 200 a day. For day to day use, this will never become a problem, but be careful when enrolling a load of users to Vaultwarden in one go as there can be 5-6 messages sent per person.
