Hi guys, hope to get some help regarding some issues I've been having lately.
Firstly, having trouble updating my install of ZCS. The url is correct but when I attempt to check for updates it returns
"Server error encountered
System failure: error parsing zimbraVersionCheckLastResponse config attribute Error code: service.FAILURE Details:soap:Receiver"
Secondly, a lot of our external mails are not coming through. After some checking I think I've figured out why. Our MX record points to a relay on the ISP that receives all our mail before sending it through to us (it's an ironport network if that helps). I think what happens is Zimbra then sees all these connections coming in from a single source and times it out thinking it's spam.
Is there a way that I can whitelist the list of IPs of the external relay so neither postfix or spamassassin blocks any external mail?
I've added the addresses under MTA trusted networks but I'm not sure if this helps.
Also getting a lot of "queue file size limit exceeded". Are these attempts at sending large attachments?
Any help is appreciated
