When connected to comcast network using my .me (apple) mail account:
Can receive apple mail (email@example.com and firstname.lastname@example.org) from IMAP
Cannot send apple mail using Apples SMPT server.
I can both receive and send using another mail account with no problems.
using iphone not connected to comcast wifi just using AT&T signal both receive and send works.
however, when I connect to comcast wifi I can only receive mail
I hve deleted the apple mail account and reconvierued it with porpper IMAP and SMTP server names, ports, user name and password.
This is how I have the servers setup:
ok I fixed the issue.
If you are using icloud with Windows 10 and Outlook you have to setup an "App-Specific password" with Apple.
Once you select and copy the password into the account setting in Outlook and use that as your passwrd.
