We currently use SMTP Email Delivery for all of our outgoing email transactions. By using the Exchange 2013 server with Office 365 we are able to confidently and securely send emails outside and inside the organization with no limitations.
  • It allows us to send email through the secure email gateway.
  • We are able to track and scan all email communications
  • It provides a way for legacy and current applications to send out notification and mass email communications.
  • As with any technology on a server, we sometimes see issues with downtime related to network changes or firewall updates.
  • It can be a challenge to work with some of our older applications when the TLS feature is used.
  • I wish there was a more direct way to reliably use SMTP for mass email sends without the fear of being blacklisted.
It works great as an onsite relay to provide email sending functionality without having to pass through the firewall in order to reach the Office 365 gateway. This is particularly evident when using older programs. A lot of the older, no longer developed, programs will only allow a hard coded port to send email. Office 365 uses a non-standard SMTP port for security. This does not allow the hard coded SMTP ports to use this service. Exchange gives you the control to change those ports and securely use the standards without compromise.
  • It's the easiest way to send mail out. No worries about complex configurations.
  • It can be finicky when used in a hybrid Office 365 environment to get the proper pathways secured and working.
  • I wish there were a better way to send out mass emails, on-site, without our domain or server IP being blacklisted.
Office 365 does use secure non-standard ports for SMTP connectivity causing a problem with older programs. SMTP Email Delivery from Exchange solves this problem by giving the network admin full control over ports and specific program connections. While we do use both Office 365 and the SMTP Email Delivery we find that a mix is needed in order to meet all expectations for our end users. The majority of our SMTP communications, for users, go through Office 365 while the majority of our applications and servers do go through the SMTP Email Delivery service.
