I believe it has been mentioned that there may be more private relays that ones may be able to use with Delta Chat? May I please ask if it is reasonable to ask for one? Thank you for your kind consideration and recommendations.
I run one you’re free to use but not here to promote myself - there’s a hacker I ran across (and now follow) on Mastodon who’s recently been advertising his new relays (multiple) and other FOSS apps, it might be of interest to you: https://haacksnetworking.org/ & Haack’s Networking (@oemb1905@gnulinux.social) - GNU/Linux Social
