Mail app cannot send mails anymore

This might help you:

Email configuration smtp doesn't work on 1and1/1und1/ionos hosting, but email app works

I tried this before … in all combinations, as suggested in another thread. ssl-587, ssl-465, ssl-25 tls-587, tls-465, tls-25 none-25, none-465, none-587 I usually get the error “connection could not be established with host smtp.ionos.de [connection timed out #110]” The funny thing: the nextcloud is hosted on Ionos/1and1-webspace as is the mail account … This should work in any way.
