Hi, We are currently having issues sending messages from our domain to all Google addresses. We have checked our SPF, DKIM & DMARC records are setup correctly. We get a bounce back message that says : host gmail-smtp-in.l.google.com [2607:f8b0:4004:c06::1b] SMTP error from remote mail server after end of data: 550-5.7.1 [2001:978:2a01:0:6:0:1089:1091 7] Our system has detected that 550-5.7.1 this message is likely unsolicited mail. To reduce the amount of spam 550-5.7.1 sent to Gmail, this message has been blocked. Please visit 550-5.7.1 https://support.google.com/mail/?p=UnsolicitedMessageError for more 550 5.7.1 information. w26-20020a05620a0e9a00b00773ae74632asi1246387qkm.604 - gsmtp Google are not being helpful & blaming Microsoft even though the same thing happens when messages are sent from Sendgrid. Does anyone know a solution to this or how we can contact someone useful at Google to help?

Hello, I have a pretty good understanding of exchange, but this is stumping me. When I terminate a user, I back up their e-mail, disable and delete their AD account and create a distribution list to forward mail to the manager, etc. Well, it turns out internal e-mails are not forwarding, only external. An internal client who e-mails this terminated employee gets a bounce-back error - proclaiming the mailbox does not exist. When someone external e-mails this terminated user, it forwards to the recipients just fine. I added the smtp e-mail to the e-mail addresses tab - as I have always done. What's extra strange is that this happens most the time, but in some cases internal and external forwarding work just as it should for random users... configurations are identical. Any ideas? Thanks in advanced.

Encountering occasional weirdness with Zimbra using web access. The following message arrived at 03:09 but did not appear on my screen until 11am. Other messages arrived as expected in the meantime.

Just a quick one that's got me a bit confused. Our staff use RM Easymail here, which is all browser based. Whenever they get an attachment, they have the choice of Open or Save. If they choose Open, the viewer app (be it word, adobe reader, or whatever) will open but can't find the file. Saving first works fine. RM have an article that says it's a problem with "locally stored temporary internet files" and we followed their instructions to clear them out but nothing changed. Any ideas?

Hi, I'm currently looking at implementing Exchange Server in our school, and another member of staff suggested looking at Escimo - Collaborative Online Learning. Its from Essex County Council and provides email for all staff. "This service is funded using special DCSF grants and will be free of charge to schools until September 2010." Has anyone had any experiences with 'Escimo', good or bad? Thanks

Hi, I have created a company wide disclaimer to input signatures for all employees using HTML. Is there a way to add an exception if the email is plain text instead of display HMTL code. Thanks

It stopped working a couple of weeks ago through our Smoothwall firewall. Nothing has changed our end so there must be new URLs or ports that require allowing through. Any ideas? Once I take my Surface home, the mail comes in fine so it's not a client issue.

Hi everyone We've recently got onboard the office365 train but have run into a problem sending mail to btinternet/openworld, virgin/blueyonder, aol.com/aol.co.uk email addresses. I've endured the torture of MS support for a few days who assure me that SPF is fine, DKIM is fine, Headers are fine, their IP's and reverse are fine. The email content is text nothing else, no fancy HTML, no fancy graphics, nothing. I've even sent a test message with MS support watching via screen sharing. I've checked our sending reputation which comes up neutral or good with services and I've checked us against block lists of which we don't appear on any. So I turn to you wonderful people. Firstly and rather unfortunately, for reasons unknown we receive no bouncebacks whatsoever, from any mail provider. The MS engineer seems as baffled at this as I am. Using message trace in exchange admin shows that our email fails to virgin/BY and aol and is being stopped for a number of reasons "null sender to multiple recipients" and variants of the phrase are most common. Other messages will simply tell us that the external mail server is treating our mail as spam. Emails to BT addresses sit 'Pending' in message trace with a 'defer' message saying we've sent too much spam. I've been in touch with postmasters at BT and AOL who both requested bounceback message and headers despite the fact I've told them the sending account receives no bouncebacks, I've sent both all the info I can but neither has come back to me thus far. We're sitting here thinking surely we cant be the only office365 school that's had this issue. Can anyone shed any light on this situation? Thanks!

Hi all, I am desperately trying to connect an iPad 2 to Exchange but it keeps saying that it cannot verify. I have typed in the email address, server, domain, username, password but it keeps saying it. I have tried different variations of the server (external IP address, name etc) as well as leaving the domain name blank or trying it with .lan at the end. I wondered if there was something that I am supposed to check somewhere on the server so that connections are allowed from iPads? It seems to work fine on other mobile devides, just not iPads. Any help would be great.

Good morning everyone! Wondering if anyone has had the same issue we're experiencing? Smoothwall seems to be all fine and dandy,,, except! A student made us aware their Mail app on Mac wasn't working. Now I presumed they had made some changes to their settings and mucked it up. But on closer inspection it seems to be a filtering issue. The email in question was a @iCloud account (and a hotmail but one thing at a time). Now they are able to receive mail but not send. Checking the web filter there is no obvious block, so I proceeded to log in myself on the Macbook (this is a BYOD by the way, not a device hooked up to our system), and found it worked fine, with my account allowing full unrestricted access. I then tried adding the SMTP domain that apple uses, to different filtering policies but to no avail. I also tried my own iCloud email when logged in as the student and it has the same issues. I've tried a few other options I've found trawling the interweb but nothing has come up trumps?! The only thing I believe is at the root of the issue is when monitoring the webfilter whilst trying to send, logged in as me it identifies the group I'm associated with. But when logged in as a student it shows 'Unauthenticated IP' group. Which seems odd as can browse and do most things normally as expected. Anyone else found this? I have opened a case with SW but feeling impatient, its Friday, wanna get on with it! Hope that makes sense. Thanks all, Dan

I am sick and tired of having our mail rejected by AOL. I have tried everything I can think of to sort this out. We are NOT blacklisted, we have Reverse DNS and we have a statit IP for the mail server. Can anyone think of other things that I need to check to be able to send to AOL? I have requested to get onto their whitelist but of course they haven't done anything about it.

Hi, {Short} I'm curious if it's possible to force everyone within our organisation (or even select people) to have a delayed delivery for their emails. {Long} Is it possible to enforce a rule on the internal organisation which means their outbound emails will be delayed by a set time? There has been cases of people sending emails quickly which includes mistakes, if we can enforce a delay, then we can help staff identify the mistake and recall it before the email has sent. Thanks. P.s: Sorry if I'm in the wrong thread.

Within the Office 365 Web App for Mail there is an option to create mailbox rules e.g. mark email from ? as read and move to ? folder. When I chose the option 'Create Rule' from the menu, it displays "The option you chose isn't available". Is there an Admin setting I've turned off? Or just a bug? I have tried other users within the organisation, and the same thing happens.

I'll explain the complicated setup I have initially... 1. LancsNGfL mailserver accepts mail destined for our domain 2. The LancsNGfL mailserver then relays that mail to an IP address 3. The IP address mentioned in 2 is then nat-ed with a port forwarding rule to my Zimbra server 4. If the Zimbra server does not have the recipient, the mail is relayed onto my Exchange server Now the problem... I'm decommisioning the Zimbra server so there's now no accounts on it. My Exchange server is sat happily receiving mail. If I change the port forwarding rule to point to the exchange server (which has a recipient rule on it accepting mail from thew LancsNGfL relay), I stop receiving mail. Changing the port forwarding rule back fixes the problem. What am I missing?

I ran the upgrade of GLPI last night. Since running the upgrade from 0.72.4 to 0.78, we are now getting an error stating SMTP could not authenticate. We are running on a Windows 2003 server with PHP 5.26, and trying to authenticate to a web based SMTP server (server name is the IP address). This worked absolutely fine under 0.72.4, however even after re-entering all details in the 0.78 setups it will still nto authenticate. I've gone back to my old installation and that still works fine so I can only presume some change of code is causing it. Hoprefully one of you guys can offer some enlightenment as this is all that is preventing me going live with the new version. Thanks

Can anyone recommend a good SMTP provider for personal use? I currently use Yahoo.co.uk with Thunderbird, for handling my mail to and from several domains I own. Service is getting pretty bad in last 6 months. Intermittantly can't send via SMTP (haven't been able to send at all for two weeks now). Sometimes can't connect either to Yahoo's SMTP or webmail. Their support isn't much help. I'm not convinced I'm even communicating with a real person - the answers aren't relevant to my questions. I used Yahoo because they're only £11.99 a year, but would willingly pay a little more for something reliable. Any suggestions? Thanks.
