Hi Guys,<br />
<br />
We have various clients using office 365 for their email. &nbsp;Strangely enough all of them are having intermitting issues sending to customer(s) who use mdaemon mail server. About 1 in every 3 emails sent to a mdaemon customer are getting terminated before the message can complete. We have checked the logs, firewalls etc and there is no pattern except for it except being customers of office 365 sending to a mdaemon mail server customer. To confirm all logs show these messages arriving and passing spam / av filters, its just at the end before mdaemon saves the message you get a socket error. <br />
Can you help us with this issue as we are have great difficulty getting support from office 365 ? Please see failure below:<br />

Office 365 Issues sending to Mdaemon Mail Server

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

Microsoft 365

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
