Cannot send mail from iPhone after iOS Update

HI,
I have updated my iPhone 6 to latest iOS 11.3.1
I am using Zimbra 8.7.11_GA_1854 FOSS
Since the upgrade I can no longer send email from my iPhone although I can receive it.
I have tried setting up account as IMAP and also as Exchange but neither setup allows sending.
I get the message fred@fred.com was rejected by the server.
These are the same credentials as used by my android tablet which works.

I tried various "fixes" for the last couple of weeks but to no avail.
Appreciate any suggestions.
Thanks and kind reagrds,

PS Anyone know how to upgrade Zimbra to latest version all I can read about says it is impossible without major work????

I don't know where you read that but I'd suggest you read the ZCS 8.8.8 Release Notes in detail then upgrade your server (after taking a suitable backup).
