Joined Plusnet fibre broadband at end of January and now I cannot send e-mails via outlook. All the settings are the same as they have always been, and are from many years ago as they are tiscali.co.uk based and have remained the same for possibly 15 years all through changes of provider, including plusnet some years back, Talk Talk and even BT.
The annoying thing is that mails come and go on my mobile using the exact settings, apart from the incoming server on mobile is IMAP, on PC it is POP3. Outgoing server on both is SMTP port 587, but when I attempt to send a mail on my PC, the message appears telling me my type of encryption is not the same as the server, incompatible is the description. There are 4 types of encryption posssible, None, Auto, SSL, and TLS but changing the settings pop up to any of the four and attempting to send a mail, gives the same error message. Surely no encryption cannot cause the delivery to fail.
Please can some one help as talking to plusnet brought the response "I cant help with plusnet settings", so how did the settings work with all my previous suppliers, without alteration but not any more.
Fixed! Go to the fix.
Re: Since changeover
@JohnBux It looks like your IP address is listed on Spamhaus PBL which means that the originating server you're trying to send from isn't 'authenticating' properly. It'd probably be easier to use our outgoing mail server instead. Can you try setting up your Tiscali emails on Outlook to use relay.plus.net as the outgoing server?
After making this post, I waited to see if anyone had any ideas, but suddenly about 2 hours later my wife asked if I had sent her a mail. She showed me the mail on her phone and it was one of the 2 that were "stuck" in my outbox due to the problems I had encountered sending in the last 2 weeks.
I went to my PC, and as I opened outlook it was obvious the messages that were stuck there had gone and were now in sent items.Who knows how or why.
The settings were as they had always been in the tools> accounts section but now my outgoing mail is back up and running.
