List mobilitains.fr and mobilitain.fr in virtual_mailbox_domains. Then, configure virtual_mailbox_maps as described in https://wiki.dovecot.org/LDA/Postfix. Look the section "Virtual users (dynamic)". With this, Postfix and Dovecot will always agree on what is a valid recipient address. There is no "easy" way to tell Postfix to replace mobilitain.fr with mobilitains.fr. The easy way causes Postfix to accept mail for non-existent addresses. Wietse
