change of sender email address doesn't change app_senders_login_maps

[chri2]

same as https://github.com/YunoHost-Apps/gotosocial_ynh/issues/149

after changing the email sender address /etc/postfix/app_senders_login_maps needs to be updated and we'd need to make sure that the update is not overwritten by conf_regen which recreates the file.

I added the following settings to get along until this is solved

yunohost app setting fittrackee mail_user -v <email sender user part>
yunohost app setting fittrackee mail_domain -v <email sender domain part>

TBH I’ve enabled this for me when I needed and it worked well, but I don’t need this anymore so if you say it doesn’t work right, I may just disabling this. Or do you find this still useful?

I just decided that I'd put changing the smtp sender address into flohmarkt_ynh, too: Things change - people might start hosting email or stop hosting email. I e.g. installed GotoSocial and looked around a bit and decided on a concept how to use it. While going through the settings I found the sender address to be one I would like to change.

I think the function is helpful, but needs work - same for flohmarkt and gotosocial.
