I rarely send emails from my Sony 10 android phone but on the 24th feb I tried to email a photo from it (using the standard android email app and via my home plusnet connection) to a friend but it wouldn’t send the email. I tried persistently many times. As I have regularly encountered issues with my plusnet router dropping connection randomly to either phone, laptop, printer, Alexa smart tvs etc I attempted restarting the router (no difference) and then I tried restoring the router to factory settings which it failed to do. Later that day I tried to send the photo by email from my laptop (w10) many times. That failed with the error message “the following recipient cannot be reached .......550 recipient rejected – relay denied”. I use Outlook from Microsoft office 2007 on my laptop and have done with the same settings without problems for over 10 years and have been with plusnet for the same time at least.
I rang plusnet and stated that I thought it was a bit of a coincidence that both my android phone and W10 laptop should both fail to send emails almost simultaneously but was told that as plusnet advised using plusnet webmail and not 3rd party email applications there was nothing more they could do. He added that if I wished my router replaced it would cost me about £100.
The next day I suddenly remembered that my Sony phone had had a system update (from Sony) about 3 days previously so I checked my email settings on that and found that the password field was blank! Once I corrected that I was able to send emails from it again. However my laptop still won’t send emails.
I can’t help but wonder if my persistent attempts to send emails from my phone without a password had triggered some sort of security flag at plusnet which has stopped me from sending emails from my laptop. I have tried changing my outlook outgoing email settings but to no avail. The settings I’ve always used have never caused problems for me before so I don’t think that’s the cause. These are my settings for outgoing mail:-
Account type POP3 Incoming mail server mail.plus.net Outgoing mail server (SMTP) relay.plus.net
Require login using SPA box left blank
Contents of more settings Advanced tab: Incoming server (POP3) 110
This server requires an encrypted connection box left blank
Outgoing server SMTP 25 Use the following type of encrypted connection box None
If I click on the “test account settings” box I get the same error message as on my failed emails
I have also tried setting up a new email account within Outlook using my usual settings but that produced the same error message.
I find Plusnet’s webmail such a pain to use, I now have to send emails from it with a bcc to myself in order to file within outlook!
Fixed! Go to the fix.

Hi @JaneC1
I recommend:
1. Pursuing the connections issue with Plusnet until its gets sorted
2. Taking a look at the Plusnet settings info at https://www.plus.net/help/email-guides/how-to-set-up-plusnet-email/
3. Using IMAP rather than POP
Plusnet does not advise only using plusnet webmail. In fact the link above says "IMAP and POP are ways you can download your emails from Plusnet systems to another email application. When you're setting things up, you'll need to choose which one to use."

I said IMAP because POP deletes mails on the server when they are read. Not relevent to your issues.

thanks again for that Dave but as I'm emailing from home as usual and emailing addresses I've used for years without issue with the same email settings I've used for years I suspect the problem is caused elsewhere. I still suspect some sort of security flag at plusnet which was triggered by my multiple attempts to email from my mobile without a password.

I'm not aware of anything like that associated with email accounts. If I understand correctly, you can send ok from your Sony mobile ? that would suggest that there is no problem with the email account. TBH its more likely to be an Outlook problem. You've only got to search this board to see the number of problems that seem to sporadically occur with Outlook
Outgoing server SMTP 25
I don't think this is the problem but the smtp port should more correctly be 587. Port 25 is used between mail servers for relaying mail, port 587 should be used by clients to submit mail.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.

Did you also change the rest of these?
Incoming server | imap.plus.net | |
Incoming port | 993 | |
Outgoing server | relay.plus.net | |
Outgoing port | 587 (recommended) or 25 |

@JaneC1 I've only scan-read this topic, but can you send to other recipients without error?

A couple more questions @JaneC1 , Which ISP is your fiend with, and how do they receive email - email client or webmail?
Also, if you try again via your phone - or laptop - and get the same response, can you copy and paste the whole error message on here - x'ing out their name of course?

sorry all. I'm sure I didn't click on accepted fix when trying to respond to posts as problem still remains. The problem is when using my laptop only, phone email is ok. On my laptop the problem remains on all emails out regardless of recipients.
Thanks to everyone trying to help.
