Phone only receiving e-mails with connected to home wifi

[#1]

I am sure the answer to this lays somewhere in the millions of "e-mail settings" posts, but I have been unable to find it, so I will kick off with an apology.

My Android phone (Vodafone) will only receive e-mails if I am connected to the internet via my plusnet router at home, which makes having e-mail on my mobile pretty useless. I am sure that this used to work, so I am guessing it's some kind of a new security feature?

My settings for incoming mail are:

Server: imap.plus.net

Port:143

Security type: None

What have I got wrong?

According to this - Plusnet email setup FAQs - IMAP 

the server settings should be this -

[#3]

Is STARTTLS required for the incoming or outgoing server?

If I use port 993 and STARTTLS then when I try to save the new settings my phone hangs on "Checking server settings". The same thing happens if I use port 992 and Security: None.

Port 993 and SSL/TLS was accepted though, so I will try that tomorrow when I am at work.

Outgoing . the incoming is SSL/TLS

The main think is that you need to set authentication on the outgoing server in order to work on a non-Plusnet connection

@MisterW  could you via the "SU space", or other means, get staff to add that info to the official documentation ?

as the official FAQ shown in  Reply #2  isn't complete with that detail missing.

Perhaps labelled "Incoming connection security    SSL/TLS"

and likewise to make unambiguous, change the outgoing to "Outgoing connection security    STARTTLS"

Having the official documentation show complete information is likely to save other people time and confusion going forwards.

@outcast Yes, I'll feed that back and sse if we can get the FAQ clarified.

To be fair, the email clients I've used have always defaulted to SSL/TLS if IMAP and port 993 are selected

[#7]

@outcast 

The feedback has been given on multiple occasions...

... and again - I have now added it to an on-going email configuration discussion thread.

Thanks. It's working fine with SSL/TLS. I have been getting spam all day while at work🙄

I am also able to send mail using relay.plus.net on port 587 with security type set to "none" but Require sign-in ticked.

[#9]

@Digsy you really should use STARTTLS on the outgoing server to ensure your authentication details are encrhypted

[#10]

I have updated the outgoing server settings now too. Thanks!
