Hello everyone, Brand New Mailcow UI from the ground up. It is faster, cleaner, and more usable than existing options. It runs as a separate Docker app. You do not modify Mailcow. You deploy it alongside your stack as a standalone webmail UI. Think Gmail, but more powerful.[upl-image-preview uuid=9b714122-6726-45b5-80c4-ab6c2d17e682 url=https://community.mailcow.email/assets/files/2026-03-23/1774303403-769565-screenshot-2026-03-23-at-55113-pm.png alt={TEXT?}] [upl-image-preview uuid=c4833053-3044-4205-b12c-0394b1c6b82a url=https://community.mailcow.email/assets/files/2026-03-23/1774303429-968069-screenshot-2026-03-23-at-55128-pm.png alt={TEXT?}] [upl-image-preview uuid=15d06eb6-e88f-45ec-ae33-ed51fe6c5128 url=https://community.mailcow.email/assets/files/2026-03-23/1774303464-75782-screenshot-2026-03-23-at-55141-pm.png alt={TEXT?}] [upl-image-preview uuid=82ab6912-086b-448a-a2f4-d72b7ec0cb2d url=https://community.mailcow.email/assets/files/2026-03-23/1774303484-528174-screenshot-2026-03-23-at-55301-pm.png alt={TEXT?}] [upl-image-preview uuid=05f207af-e3d1-4f99-83cb-9c11a14d7e2f url=https://community.mailcow.email/assets/files/2026-03-23/1774303484-352456-screenshot-2026-03-23-at-55250-pm.png alt={TEXT?}] [upl-image-preview uuid=1dab4421-705c-41b5-aae3-a4ef6977f2ea url=https://community.mailcow.email/assets/files/2026-03-23/1774303484-216682-screenshot-2026-03-23-at-55242-pm.png alt={TEXT?}] Also Launching iOS App for this soon let's go MailCow Community

Brand New Mailcow UI from the ground up. It is faster, cleaner, and more usable than existing options.
It runs as a separate Docker app. You do not modify Mailcow. You deploy it alongside your stack as a standalone webmail UI.

Think Gmail, but more powerful.

Very cool. But it seems it lacks permissions and sharing function that SOGo has. Is this planned?
