I would also like to know the answer to this issue. I do not have emails being rejected, but one of the DNS tests I use reports this problem on all my websites on my Plesk server (VPS @ GoDaddy)
What email server are you using? Also I would recommend reading the following for better assistance:

Hey, I'm sorry, my server details are:
Your operating system Centos 6.3
Your current used Odin - Product Plesk 12.0.18 - Build 1200150817.13
Your depending installed mail - server software Postfix

Your question might be better answered if you posted in the Plesk 12.x for Linux (http://talk.plesk.com/forums/plesk-12-x-for-linux.735/) instead of this section Plesk 12.x for Windows
In either case you might want to double check the configurations of your PostFix configuration files (/etc/postfix/main.cf and /etc/postfix/master.cf) to make sure everything looks correct. I'm not running a Linux box with PostFix so I can't see where in the config that needs to be edited but poke around and see what's up and might want to ask in the correct section for better help.

Hi Drew_Johnstone,
even that you posted your question in the wrong forum section, please be aware of the following facts:
SPF:
You use a very strict SPF - rule: v=spf1 +a +mx -all
Please be informed, that the selector "-all" states clear, that if any of the checks fails, the receiver should deny the mail - transport with a "hard fail". Please read http://www.openspf.org/SPF_Record_Syntax to inform yourself about better solutions, or use the suggestion from: http://talk.plesk.com/threads/email-issue.329052/#post-768811
DNS:
Please keep in mind that reverse checks are done by most eMail - servers. "Reverse DNS does not match SMTP Banner" states clear, that your IP doesn't match your configuration.
Please note that "iwphoto.co.uk" does point to "87.76.30.119", but "87.76.30.119" on the other hand points to "fh.totallytech.it" and isn't included in your SPF - settings. When a mail - server connects to "87.76.30.119", your server will answer with:
The forum contains several solutions and work-arounds. Please use the Forum Search and use the search term "Reverse DNS does not match SMTP Banner".
DMARC:
Please consider to use an additional "dmarc" - record for your domain, in order to avoid eMail - delivery - issues.
