Why are my emails being treated as spam?

Hello @mavison .

Re: The mail server responded: Error: Queue file write error.

I was moved to Greenby in about February this year.for my emails, and I got moved from Plusnet to EE on 23 April for my broadband. Which of them should I raise a ticket with? Just asking for clarification.

The Write Error is from the SMTP email server, and your emails are now hosted by Greenby, so it is their problem.

Do not get fobbed off by the bot - it is a known problem and has been known for over 6 months, and it is getting worse!

Hello @mavison . I've raised a ticket with Greenby, and I have received a reply that I change "relay.plus.net" to "mail.enmail.co". I have been into Mailwasher and done that wherever I have found "relay.plus.net", and I have gone into Thunderbird to do the same. I didn't find any in Thunderbird but I did find that SMTP was set to "mail.plusnet.enmail.co".

Why the difference?

Only time will tell if the changes and/or this difference solves the problems I have been having or cause other problems. Will try to let you know

My thanks to you and to @pvmb  and @PhilipHeyes  for your help

I believe the server addresses relay.plus.net still point to Plusnet servers, but the ones ending in enmail.co point to Greenby servers.

My server is relay.force9.net, which apparently does point to a Greenby server. My problems with Write Errors started the day when I was migrated in December, and relay.force9.net changed from pointing to a Plusnet Server to a Greenby one. And the problems have continued since then - indeed, in July I have recorded a 23% change of a send failing, the worst month so far.

It will be interesting to see what changes you see using Greenby servers.

Hello @mavison . I was curious as to why today Greenby pointed me towards changing "relay.plus.net" to "mail.enmail.co", whereas I guess during the process of moving from Plusnet to Greenby back in February or March I was told to change "relay.plus.net" to "mail.plusnet.enmail.co".

Why the addition of plusnet in one version but not the other? Does this mean both should include "plusnet", or neither should include "plusnet"?

No idea, I am afraid. I have learnt though that what Greenby say may not sometimes be the whole truth.

I have not had to change any settings for the migration - but these things do seem to depend on what settings you had, and what 'brand' of Plusnet email you had.

Never mind. I'm grateful to you for your help. All the best
