Emailing to Smart Groups
by geoffreyparker - 8/14/13 3:34 AM
I am a Mac Air 10.8.3 user. I have 16 Smart Groups of contacts for an event I manage, to all of whom I send out monthly notifications. There are no more than 90 contacts in each group and this has worked very well for 7 years. The only problems in the past have occurred when I send out emails to too many groups in the same session (I believe this is called 'tar pitting'), when on my 9th or 10th group, I get the message:
"Sending the message content to the server failed. Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent."
This has always righted itself if I turn the computer off and resume a few hours later.
But since yesterday I have been unable to send any emails to any smart groups, getting the above message straight away. However Connection Doctor shows "SMTP: Connection to server succeeded; login not required" and "POP: Connection and login to server succeeded."
Emails to individuals however send without any problem, likewise I receive emails without a problem. I deleted one smart group, and then created it again under the same name, hence with the same contacts. This too did not send. I created an entirely new smart group with a new name, containing some contacts chosen at random. This did send without a problem.
My ISP provider, Madasfish, tell me there are no reasonable limits to the number of contacts in Smart Groups and the size of my emails, about 50 kb, is also not an issue.
Can you explain what has happened and what I should do?
