Dear Sir or Madam,

We have been experiencing delivery delays for approximately one week now and was wondering if any of the sending SMTP Server IP Addresses have changed on your end so that we would need to update the inbound connections in our Firewall Rules.

It seems like we eventually get all E-Mail's delivered, but most are delayed by 10 to 30 minutes (approximately).

Please advise. . . Thank you!

162.216.240.0/22
142.202.188.0/22
107.161.27.201/32
207.38.69.0/24
207.38.70.0/24

These IP ranges need to be whitelisted in your firewall.
