Whats the maximum size of message I can send on Herald?
The size limit for sending a message using Webmail is 15MB. This includes the email ‘envelope’ and any attachments (external email systems may have a lower limit). Email attachments increase in size by around a third when sent, which means that the maximum size of a file that can be sent as an email attachement is around 10MB. You can send larger files if you use a mail client to smtp.ox.ac.uk (see configuration information for your mail client of choice for details).
