    How to configure the allowed characters in a user's e-mail address

    • Article Type: General
    • Product: Alma
    • Relevant for Installation Type: Dedicated-Direct; Direct; Local;

    Desired Outcome: Add _ before @ in email; add third section after @


    The allowed characters and formats for an e-mail address are configurable:

    1. Go to Alma > Administration > User Management Configuration > Configuration Menu > Other settings

    2. Configure the email_regex parameter to add the desired characters in the desired locations.
    For example:
    (^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$)|\s* - doesn't allow "_" before the @.

    (^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z_])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$)|\s* - does allow "_" before the @.

    Note the "_" in the allowed characters before the "@".

    3. To change the number of segments, repeat the section between the "@" and the first '*' after the "@", including the '*'
