Perl execution failed : Header Checks "edit_name_header_checks"

Hi,
I’m not able to edit Header Checks tables in “regexp:/etc/postfix/header_checks” in GUI. Manual edit is possible but looks like my lines are not correctly processed. Thanks for your help.

Error — Perl execution failed

Can’t use string (“edit_name_header_checks”) as a subroutine ref while “strict refs” in use at /usr/share/webmin/postfix/edit_mapping.cgi line 54.

Hi Fabio, sure one of the team will respond soon, usually quick with regards to perl problems.

Maybe not. :roll_eyes: As both WM & VM are written in Perl I expect Jamie will sort this for you soon, hopefully.

Hi,

same error here, with Almalinux 8.10 & Almalinux 9.8
