This on a 15″ M2 MBA on MacOS 14.4.1
Only recently I began getting a 554 5.7.1 SMTP error when sending iCloud mail. The Connection Physician log says:
READ Mar 26 04:50:47.891 [kCFStreamSocketSecurityLevelTLSv1_2] -- host:smtp.mail.me.com -- port:587 -- socket:0x60000803dbc0 -- thread:0x6000071109c0
554 5.7.1 : Consumer host rejected: Entry denied
This error message appears to point an issue with our exterior IP tackle. Nonetheless, no different machine on the LAN has this downside. iPhones, iPads, different MBAs and an M1 iMac can all ship iCloud mail with out error. Notice that we’ve got a dynamic IP tackle which adjustments not less than as soon as a day.
The person error message says:
As you possibly can see, the at present chosen server is Google, which is inaccurate. For some motive, two iCloud servers are proven. One in every of them, seemingly at random, will work whereas the opposite one is not going to.
It is type of a ache to need to undergo this each time I ship iCloud mail.Mac O
