Madasafish emails to gmail bounce

[#1]

Since around the end of March we have found that messages sent from our <name>@<name>.madasafish.com email accounts to @gmail.com addresses generally bounce, with the response below (edited for anonymity). Is there something in the madasafish email server that needs updating? Sending to @gmail.com addresses always worked normally until recently.

I can PM the full message source to a sysadmin, if that helps.

Many thanks for any thoughts!

There are several more qualified to answer this question ( @Townman ?)  but my understanding can be summarised thus:

1. There is an internationally recognised agreement that emails do not need to be authenticated by the addition of SPF and/or DKIM.

2. The default Plusnet SMTP servers used to send emails add neither.

3. Gmail have decided to ignore the convention and now insist on one or the other.

4. I understand (but could be wrong) that a record can be added only if you have  Plusnet hosted domain.

I have no idea if Plusnet will make the necessary changes but bearing in mind that they no longer provide an email service to new customers…..

Hi Rom,

You do not explicitly state, but are you sending this from a PC email application rather than using Webmail?  If my guess is correct, does the SMTP server settings need modifying to "Requires authentication - use the same as the incoming server"?

@Baldrick1

Those indeed could be complicating factors, but my hunch here is that "unauthenticated" is indicative that the connection to the SMTP server from a device on the network is operating (configured) as per the unhelpful advice in the Plusnet email configuration guide - "Authentication ONLY required if connecting off-network".

@account.plus.com email addresses do get DKIM, but I do not know if that applies to MAAF email addresses too.

@Baldrick1 

Thank you for that, which is very helpful to understand (if not encouraging...)

@Townman 

Thank you: yes, quite right. We're using PC clients. I'll adjust the settings as you suggest and see what happens.

V grateful for the prompt responses.

I have just seen another thread suggesting that something (else?) is being investigated WRT sending to Gmail. for Plusnet accounts.  Can you please be sure to report back if (a) the above fixes this for you or (b) the characteristic of the problem changes after ensuring that authentication is enabled.

[#6]

Yes, I'll report back. Thanks again.

Hi,

I have also started getting the same gmail bounce issues.

An earlier thread, link below, gave a fix...but this doesn't seem to work.

https://community.plus.net/t5/Email/Replies-to-Gmail-accounts-being-rejected/m-p/1914861#M42628

Please could you explain (for someone with really basic knowledge!) where and how to alter the SMTP as suggested in this thread @Townman ?

Or if there is any update on what the problem is? 

thanks

PS: I'm an original Force9 user...

@Townman 

Reporting back on the 'authentication' fix: it seems to have done the trick - thank you.

We have had one email (of many) to an @gmail.com bounced with a 'remote server ?? responded with <name>@gmail.com ??:??' - which is a) a different issue, I guess; and b) not so much of a problem, since the email was successfully delivered when we re-sent it.

You need to change the OUTGOING server settings in your email client - which email client are you using?

@rwm32 Delighted that advice fixed the issue for you.

Hi,

Thanks for the response, I'm using 'mail' with iOS and macOS...this is what I've had as my settings forever!

[#11]

Those environments normally enforce authentication...

iPhone...

1. Settings
2. Mail
3. Accounts
4. Select relevant account
5. Select Account
6. Select SMTP
7. Select PRIMARY SERVER
   1. Server should be enabled
   2. Host Name - relay.plus.net
   3. Username - accountname or accountname+mailboxname
   4. Password - that applicable to the above
   5. Use SSL - enabled
   6. Authentication - password
   7. Port - 587
8. Click DONE - account should be verified successfully
9. Click back to account
10. Click DONE

macOS should be similar.

Thanks,

See screenshots in thread above, have double checked all...I think that looks right.

Only bounces from gmail...still doing it...

[#13]

I have the same issue - any email from my @madasafish.com account to gmail get bounced back with an error.

this has started in the last few weeks.

I am using my email through Outlook with my own domain - hosted by Plusnet.

Plusnet say it is a problem with outlook and they can't help.  How would I get admin access to the domain to make the changes required?

I would need a very basic instructions as I am a complete novice!  Thanks

@sunlive "I am using my email through Outlook with my own domain - hosted by Plusnet."

I have the same but with   @[my account].plus.net email.

After a lot of searching the posts, this answer here seems to have fixed the issue for me.
No idea if it's the same for Madasafish though.

@Porthrepta   Thanks - I've had a look at that  l but when I click the link  to the members I get the main log in page for Plusnet.

How do I get to the member centre to configure and add an MX record?  Thanks in advance for any assistance.
