Guys. not quite IMGATE but our server is imail!, however, since you lot know email workings so well, I ask for help.
I am having a issue here. Below is the full conversation so far. Basically, we send an email to gspfareham.co.uk. The dns resolves the primary MX to a server that doesnt work. we are unable to get emails sent to them. The reply back from glyn is supposed to be the answer but I dont get it. Is this a config error on our imail server? my lack of experience or what. Your advice and help is much appreciated. Thanks in advance. Aaron Glyn Balsdon wrote: Hi, I have checked the details in your email and can confirm that this configuration is not unusual. The primary MX record is set to mail-backup.gspfareham.co.uk, which will be processed by NewNet in the event of a failure. As this is not currently active (bourne out by your tests), the servers at NewNet will direct to the secondary MX record, which is the live system at Gyoury Self. The failover only works if you send email via DNS, or direct send to post.newnet.co.uk. If direct send is employed to the mx record either via host name or IP address, the failover does not occur and mail will not flow. I am assuming you are using the latter method of communication on your mail server. If you have any comments on this, I would be happy to receive them. At this stage there are no charges for our customer as this falls under our free support remit, but should further investigations or reconfiguration be required, time would be incurred from their block time agreement with us, and I would need approval to continue.

From these, I can determine that the mail is not leaving the PSC mail server. Delivery is being attempted but not succeeding and thus the failed delivery message is created. In this instance, I would advise contacting the Postmaster at the college to trace the problem. The only fact I can think of at this stage that may assist the diagnosis is that both Gyoury Self, and ourselves use NewNet as an ISP. NewNet have no reported issues at present, and I can confirm receipt of mail from other sources. They do block reverse lookups on their mail systems, but normally this is an issue for sending rather than receiving. Hope this helps. If you require further information please let me know, and we will see if there is anything else we can do. Regards, Glyn Balsdon -------------- /End Original Email ---------------------------- Glyn, I have investigated the problem with regards to us not being able to send email to gspfareham. You are right in saying that the emails are not leaving the college. This is because the primary MX does not work. As you can see from the results below. I have got the Mx records from the dns entries, then have tried to telnet port 25 to the primary MX (mail-backup.gspfareham.co.uk), this failed. After trying to connect from 3 different sources, I can only assume that this server is down. However, The second Mx does work, So we are curently mapping all mail for gspfareham to this address. This will provide a tempory solution until you can fix this.
