Setting up autoresponders (out-of-office replies).
Vacation auto-replies, support acknowledgements, and what to avoid so your auto-reply doesn't itself get marked as spam.
Going on vacation? Acknowledging support requests automatically? For the mailboxes of your website (email included with hosting), the autoresponder covers both cases.
Using Rivervo Business email? The panel has no auto-reply setting for Business email. Check your webmail's settings (app.aegis.email) or your mail app's own out-of-office feature instead.
Create an autoresponder
Project → Email → the mailbox → ⋯ → Autoresponder:
- Sender name: the name the reply comes from (optional)
- Subject: subject of the auto-reply
- Text: the reply itself
- From / Until: when it works (optional — empty means from now on, until you turn it off)
- Once per sender every … hours: 24 is a safe default (important to avoid loops)
Save. The mailbox then shows «autoresponder on».
Vacation example
Subject: I'm out of office until 15 May
Hi,
Thanks for your email. I'm away from my desk until 15 May 2026.
For urgent matters, please contact my colleague at colleague@yourdomain.com.
For general questions, my team will respond when I return.
Best,
Your NameSupport acknowledgement example
Subject: We received your message — Your Company Support
Hi,
Thanks for reaching out. We've received your message and will reply as soon as we can.
In the meantime, our help pages may already have the answer:

— The Support TeamImportant — interval to avoid loops
The Once per sender every … hours setting prevents your auto-reply from triggering THEIR auto-reply, which triggers YOUR auto-reply, etc. — known as "mail loops" and can spike a queue to 10,000+ messages in minutes.
24 hours is a safe default. Lower than 4 is risky.
Stopping early
If you came back early from vacation:
The mailbox → ⋯ → Autoresponder → Turn off.
Why your autoresponder might not fire
Sender's mail server doesn't expect responses. Some mailing lists (noreply@, notifications@) put Auto-Submitted: auto-generated headers. Autoresponders are designed to skip such automated mail — to prevent loops with newsletters.
Sender's mail bounced. If the original mail was undeliverable (bad SPF, in spam, blocked), there's nothing to reply to.
Outside the schedule window. Check the From / Until dates.
Same sender within 24h. They got their auto-reply already; the next one waits 24 hours.
What NOT to put in autoresponders
- Don't reveal you're traveling and the house is empty. "I'm in Bali for 3 weeks!" → hello, burglars.
- Don't promise specific response times you can't deliver. "I'll respond within 1 hour" — even on holidays?
- Don't include too much personal info. Cybercriminals scrape autoresponders for OOO patterns.
Generic, professional, brief.
Alternative: filters + canned response
For more sophisticated handling (auto-reply only to messages with specific keywords, route certain senders to specific replies), use the mailbox's Filters (mailbox → ⋯ → Filters): conditions on the sender, subject or body, then move, forward, refuse with a message or pass to a program.
