Limiting or delaying outgoing e-mail blasts

We have our GWIA (8.02 HP2) running on
a NetWare 6.5 SP8 server (VMware server).
We've been having a problem with our GWIA's server
rebooting (no record in Abend.log or SYS$LOG.ERR).
Our Vsphere Client reports a spike in CPU and Memory
Usage at the time of the reboot.
IF this is related to someone sending out an e-mail
blast (lots of recipients) ... is there a way to
limit outgoing e-mail to a certain number, per hour
--or, possibly, delaying responding to such volume
to lessen the impact on the GWIA?
Thanks,
-Steve

Hi,
My random thought generator came up with these:
Virtually all of GroupWise uses folder based queues to store up messages. So as a practical matter, reducing the number of SMTP Send Threads will reduce the number of simultaneous conversations. But any time the server spontaneously reboots its going to be a hardware issue - in your case a virtual hardware issue. You can use any SNMP trending system to monitor the number of threads in use, the depth of the send / recieve queues for the GWIA or set thresholds in GroupWise Monitor so you can be alerted when it gets clogged up.
The file based queuing also means that you can run out of disk space. So if you have crafted a rather modest VM, it may run out of space. If the GW system lives on SYS, then the queued mail competes for space with the swap file.
Are the agents running in protected memory? You may want to switch that around to see if it prevents an issue. If you are running them in protected memory - this means they have the potential to swap - which can run into the above disk space issue.
Its also possible to disable automatic restart after abend, so that you can catch it in the act. But then you would need to baby sit the server and ensure you did not have extended periods of down time.
Is the VM dedicated o being a GWIA? Or is thi server doing other stuff?
Also its VERY easy to prop up a SLES 11 VM and install the GWIA on it. You can have any number of GWIAs running in parallel, and use the new one as your default outbound GWIA - leaving the inbound path unchanged - no mucking around in the MX records, etc.
FWIW, we used to have this issue as well, about once every 3-6 weeks and had a "sacrificial server" set up - but now under Linux, it restarts just the GWIA without any loss of service. At that time we had 4 GWIAs and 4 Webaccess instances because they would up and die. Our reliability and uptime with GW 8.0.2 on Linux for our 3700 users is now > 99.997%. I like NetWare as much as the next guy, OK, probably more :-) but it getting long in the tooth. And we are very happy NOT to be running GroupWise on NetWare.

  • Ban Outgoing e-mail addresses and delay mail send

    1. We want to limit users ability to send outgoing e-mails to particular e-mail addresses.
    (Either by use of blacklist (by domain or specific e-mail address) or if necessary by limiting it to addressbook addresses. We would prefer use of blacklist.
    2. We also want to automatically hold all e-mails until either
    a) manually released or
    b) if not manually released, e-mail held for 1 hour (- allows mail to be retrieved if "accidentally pressed send" events occur ).
    Any ideas for add-ons or other suggestions please
    (Mac Mail and Entourage in use, but could standardise to only one)

    It may be a transaction message. If so when you check tomorrow, check on this chart. See if you see your error listed. http://www.blackberry.com/btsc/KB02960

  • How can I delay delivery of an outgoing e-mail?

    Please bare with me if this is very elementary, but I am new to OS X.  I want to set up e-mails but specify a future date for their delivery.  I know how to do it with Outlook on a PC, but have found no option for such with OS X.  Does it have anything to do with using IMAP instead of POP?  Is there a better mail client to use with OS X than the default Mail?
    Thanks!

    Lots of questions...
    There is no way (that I am aware of) to delay sending E-mail from the Mail application.
    IMAP/POP is not a factor, as far as I know.

  • My N97 is no longer able to send outgoing e-mail t...

    After a hard reset, my N97 is no longer able to send outgoing e-mail through my Gmail account.  I had to set up my e-mail account again on the N97 after the hard reset. I created the e-mail settings with the mailbox guide.  I can retrieve my e-mail messages but I am no longer able to send a new e-mail message. 
    Now, when I create a new e-mail message (Options, Create message, E-mail) and I select "Send" after creating the message, the N97 keeps trying to connect to my mailbox and gives up after several minutes.
    Before the hard reset, I had no problems receiving and sending e-mail messages on my N97, using my Gmail account. What should I do to make it send new e-mail messages?
    Solved!

    Sounds like something is wrong in your settings,
    Either delete the account from your phone and set it up again or use the G-Mail website help to find the correct settings and manualy check and adjust your phones outgoing settings to match
    = =
    I already tried those without working.  I have deleted the account from my phone and set it up again.  Also, I used the G-Mail website Help to find the correct settings and manualy check and adjust my phone's outgoing settings to match.  It is not sending the outgoing e-mail messages.  I keep getting this notice: Connecting to mailbox.  After a while it stops without sending the e-mail message. 
    It wasn't like that before the hard reset.

  • The e-mail message could not be sent. Make sure the outgoing e-mail settings for the server are configured correctly

    I have a 2 server SharePoint farm.
    All outgoing emails were working fine.
    I just restarted both servers and now after that none of the emails are being sent. I am using OOB publishing workflow and it shows message:
    The e-mail message could not be sent. Make sure the outgoing e-mail settings for the server are configured correctly.
    Even if I setup Alert on some list, it doesn't send email.
    I have checked that outgoing email setting in CA is defined and like I said it was working fine without problems but after restart it is showing error.
    What could be the cause of this and how to fix it?
    EDIT
    I removed outgoing mail server in CA, added again and restart IIS but still emails from OOB workflow is not being sent. But email from Alerts are being sent. Don't know what to do now.

    This is really weird, It works when an alert is set but workflows doesn't send emails... Can you create a simple 1 Step workflow in SPD to send an email when a specific field is set. See if this sends an email..
    AJ MCTS: SP 2010 Configuration MCSA: Windows 7 If you find this post useful kindly please mark it as an answer :) TY
    I created a test workflow which sends email to user and it is also not sending email. But I am getting email from SharePoint regarding "variation" page changes as well as alerts which I told above.

  • E Mail blasting?

    it does not seem that the mail software version 4.4 that came with my i Mac can handle sending out over 500 emails at once.
    or what some would call an e mail blast.
    anyone else ever had this problem, or some info

    Sending out 500 emails should not be a problem. I run a website that has just about 7,000 members.
    Every now and then I send them all a email.
    I checked with my host sometime ago when I had around 5,000 members about emailing them all at once and asked if it would be a problem. I email them through software that sits on my host server so thought it was best to ask them.
    I was told it would not be a problem and they host sites that send out many more emails at a time then I do.
    Maybe if your spamming using email list all the time it's different, but if your just sending out a monthly news letter or what ever to only 500 people at a time I don't see were it should be a problem.

  • The e-mail message cannot be sent. Make sure the outgoing e-mail settings for the server are configured correctly.

    Hi,
    I have SP 2013, and it was working properly. and workflows send emails perfectly. yesterday, i decided to build a fresh site collection so i deleted the old one and created a new one. now, workflows are unable to send emails. i'm sure it has nothing to do
    with my mail server cuz no changes happened to it. i'm sure about the settings for outgoing mail on central admin. all i did, was to enter mail server IP in outgoing mail field and email below it.
    in the workflow status the status says "error" followed by this message: "The e-mail message cannot be sent. Make sure the outgoing e-mail settings for the server are configured correctly."
    Any help please?

    Hi,
    According to your post, my understanding is that you failed to send email after building a fresh site collection.
    I recommend to verify that you have entered your SMTP server name correctly.
    You can add it as FQDN e.g. ServerName.DomainName.

  • The picture ID on my outgoing Mac mail  is not mine -- it's the photo of boyfriend of my mother in law is appearing as my ID photo.  I have no link or connection with anybody  or other accounts whatsoever, and I don't have ANY third-party networks myself.

    The picture ID on my outgoing Mac mail  is not mine -- it's the photo of boyfriend of my mother in law is appearing as my ID photo.  I have no link or connection with anybody  or other accounts whatsoever, and I don't have ANY third-party networks myself.    HELP!!!

    Nobody but you sees that photo, it does not appear on outgoing emails.
    To remove the picture rather than change it, open Address Book and select your personal card, then from the menubar select Card > Clear Custom Image. Now the system will use Apple’s generic user picture in the login window and System Preferences’ Accounts pane. Mail and Address Book will remain blank until you designate a new picture in Address Book or System Preferences > Accounts.

  • ServerSideSync: track outgoing e-mails

    Our customer wants to have the e-mails of thier sales to be tracked automatically. No matter if the e-mails are sent via outlook, tablet or mobile. They can't install CRM Outlook client.
    ServerSideSync works perfectly for this scenario for incoming e-mails. They are created as an e-mail activity for the corresponding contact.
    Outgoing e-mails are not tracked according to Microsoft and our own testing. Microsoft idea is to use crm e-mail activity in web client for e-mail. This is not practicable for our customer.
    Any ideas how we can help our customer with a good solution?
    Thanks! Adrian

  • Add "Sent via" Line To Outgoing E-Mail From TREO 700wx

    I have a couple of users who would like to have the "Sent via" line added to e-mail that they send from their TREOs.  This is similar to the line added to an outgoing e-mail message when being sent from a BlackBerry device.  Is this possible?  I've looked everywhere in the phone that I can think of, but have come up empty.  Any information would be greatly appreciated.
    Post relates to: Treo 700wx (Verizon)

    AS you've seen on the Blackberrys  that message "Sent by my Blackberry" is basically a footer or signature on the message. On the 700wx to set this up you need to go to Start>Messaging>Menu button>Tools>Options and it should open to the accounts tab at the botton with a signatures button on the right side. Click on the signatures button and There you select the account and whether you want to use it for replies and forwarding as well.

  • How can I permanently remove built-in formatting for outgoing e-mail?

    Formatting changes during composition of outgoing e-mails. When I change the selection of font and/or font size, the formatting values still change while writing. I would like to permanently disable the default formatting. Can this be done? Thanks.

    My mistake my e-mail is not Outlook but is mac mail.

  • What is the outgoing (SMTP) mail server for iCloud?

    What is the outgoing (SMTP) mail server for icloud?

    dominic23:
    That's just the name/description you can give the server that appears in Mail's preferences for that account.
    After selecting Edit you can put in whatever you want in the description. 
    advisor81:
    Why do you need to know the name?  If you add an iCloud account in Mail all you really need is your Apple ID and password.  The servers are automatically assigned.

    Up until last week, I was able to send outgoing e-mail from my me.com account. Now, I can't. I read somewhere that if you were away and connected to another server and then put the computer to sleep, that could be the problem. Any advice would be greatly appreciated.
