Cannot send email using p71-smtp.mail.me.com in iOS 15.6

Follow-up to my question. The problem was caused by my SurfShark VPN. They, apparently with little or no notice, stopped supporting port 587. However, that being said port 587 should still continue to work on SurfShark's German static IP servers No. 1-3. I can confirm that it does.

An alternative would be to configure your mail to use port 465 or 2525. If they, for some reason, do not work then accessing email through a browser is another alternative.

Here are the steps to configure your email for port 465 or 2525.

Click on the Settings icon.

Scroll down until you see Mail, Contacts, Calendar. Click.

Select the Outgoing Server from the left menu.

Click on the email account you want to edit and click Edit.

Click on the email account again to open the Accounts screen.

Click on SMTP under the Outgoing Mail Server.

Click on the outgoing mail server under Primary Server.

Click on Authentication and select Password.

Click on Server Port to change the port number.

Change the port to 465 and select SSL from the encryption drop-down menu.

Hope this helps (and makes sense).

Thank you for the response. I followed your steps but to no avail. Then I discovered that the root cause of the issue was a change made by SurfShark VPN. I have posted the resolution as a [reply] follow-up to my original question.

Thanks again.

See my [reply] follow-up under my original question. My solution will probably not help you but you should be aware of it, especially if you use SurfShark VPN. I use that on my iPhone and NordVPN on my MacBook Pro. I did not have the same trouble on my MacBook. If you use a VPN then you should look into that possibility for your problem.
