Is there some kind of limit of how big the body can be, when sending a form with action="mailto:"? Unable to send body greater than a specific length, in my case 2107 character.
Thanks in advance.
In practical terms, no length at all. Using mailto:
actions requires particular combinations of email clients and web browsers that don't have enough market saturation to make it feasible to use mailto:
URIs with forms on the WWW.
Use a server side program (e.g. written in Perl/PSGI or PHP/mod_php) instead.
