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 @

Procedure:

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 '*'

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