I use 123-reg to forward emails sent to my private domain to virginmedia and to gmx. I send them in parallel to two destinations because of previous problems with mail not reaching virginmedia. Usually both arrive together. On Thursday 4th August, three emails which arrived in my gmx box did not arrive at virginmedia (not even in the spam folder). Over the following days, these have arrived in my virginmedia mailbox, the last arriving at 8.31 today (8th), more than three days after it was sent.
Any ideas what might have caused this? I can send the headers privately if that would be useful.
I have had very similar problems over the last week, with many of Thursday and Friday's emails to my ntlworld.com address via 123.reg still turning up this morning and delay messages going out to senders. I checked with 123Reg and they suggest the problem is at Virginmedia:
I've checked the email logs and it seems that the delay is due to the destination address settings for ..........@ntlworld.com.
From my end, I can see that there is an issue with the current MX records.
I would recommend getting in touch with your mail provider for further assistance
So I would welcome help on this, as I am a long-term customer and would much prefer to remain so.
It's all much simpler than this - I suspect. VM have introduced rate limiting from IP addresses that they regard are sending spam. It is an excellent deterrent to spammers but the severity of the limiting is impacting on genuine e-mail recipients. VM say they have looked into this and have corrected the issue. But I have seen posts which indicate this may not be the case. Both of you - wait here for a VM Forum Team member to respond. Will take a couple of days.
Superuser 2017/18 Use Kudos to say thanks Mark answer as "helpful" only when the problem is solved Please don't send me private messages unless I ask you to. I do not work for VM. The advice I give is based on my best understanding of VM policy and practice. You rely on it at your own risk.
I'm afraid I spoke too soon - the problem continues. Irregular delays in emails - some arrive more or less on time, some are delayed for hours, some disappear completely. Interstingly when emails are sent overnight or early morning they seem to arrive on time, which suggests this is also related to the overall volume of email being fowarded from 123-reg to Virgin?
Thanks for getting back in touch, I am sorry to see you have started to have trouble again, please pop across the headers of the delayed mail across to me via PM and I will take a further look into this for you.
