Question

How to add _ before @ in email?  

Answer

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 "@".
 

Additional Information

Please see more suggestions in this article: "Field Email Address must have a valid form" when updating a user". 

There are several online resources available to aid in constructing and testing regular expressions e.g. http://www.regexr.com

• An earlier suggestion seems not to be working (it is not in effect) any more:

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*

This suggestion causes errors if the email is added in Alma, and can't be saved in: regexr.com
