Below is a list of all the MailWish MX records information. All have the same priority, we recommend adding them all for maximum resilience:

Name/Host/Alias Time to live (TTL) Record Type Priority Value/Answer/Destination
@ or leave blank 3600 MX 10 mx001.cloudus.rs.oxcs.net
@ or leave blank 3600 MX 10 mx002.cloudus.rs.oxcs.net
@ or leave blank 3600 MX 10 mx003.cloudus.rs.oxcs.net
@ or leave blank 3600 MX 10 mx004.cloudus.rs.oxcs.net

Make sure you add @ or if you using 2 mail companies, we suggest you add the MX record under subodomain.yourdomain.com and don’t delete the other MX records if exist.
