emails being returned undelivered

Anonymous — Thu, 16 Feb 2017 00:00:22 GMT

Hi my internet host migrated my account to a cloud. After a week they finally sorted out the problems with my email outgoing and incoming server settings and it appears ok. The following day both mobiles stopped sending or receiving so I altered the settings to the ones sent to me for the PC. That helped and we can send and receive e-mails but... if we send an mail with an attachment it fails, if we follow a link it fails. The same email sent to myself or the other phone with the same attachment sends and receives ok? I suspect that the server settings are wrong and I can get no help from TMD. Any help with the correct settings will be appreciated.

Lastly and not connected to above, for maybe a year now I am unable to return or send e-mails to anyone at a btinternet.co.uk address it bounces back as undeliverable. TMD my host finally gave the following answer to my many complaints :- "btinternet.com" is not pointed to our infrastructure. What that means I do not know, my first reaction is well re point it then but I know nothing about such things, how ridiculous though that I cannot reply to someone sending me mail from a bt address. When i see them or contact them by phone they all say well we are receiving other mail ok so it must be your end.

So what is the problem please, again any help will be welcome thank you. I had someone tell me that they too have a similar problem with bt and its quite common ?????

@Anonymous You will need to persevere with BT as this is an o2 forum & they can't do anything about BT issues

Who is your email provider? Who are TMD?

1.Unfortunatley o2 dont like email being sent on port 25, for obvious reasons across its network, for a couple of my domains, i have to use port 26 or port 587 (imap) for outgoing mail and 993 (imap) for incoming mail, both with ssl switched on.

2. Btinternet.co.uk doesnt exist as a domain, with a valid mx record so im not surprised it fails, in fact it doesnt have any DNS records associated with it at all. btinternet.com points into BT's internal network (mx.bt.lon5.cpcloud.co.uk) its no longer mananged by yahoo.

Do you have the NDR (Non-Deliverable Report) with the full error code such as x.x.xxx

Looks like a US based hosting company with a database in the UK. Whoever they are, the OP's issue is with them and BT. Nothing to do with O2 as far as I can make out.

Port 25 is now for internal email only....

I don't believe it is either but we may be able to advise on a workaround.

Just my 5 pennorth here. There is no such internet address as btinternet.co.uk.

It's btinternet.com. I know as I am with them. Maybe completely different to what the op is posting about but some will remember I had to change my bt internet email address to a gmail one for anything O2 related.

They simply stopped coming in. At the time it was thought lithium had an issue with BT...

No not technical...and maybe irrelevant but thought it was worth a mention

My btinternet email works perfectly fine with any other site...but won't accept O2...
