[Mailman-Users] Erratic mail delivery times

I'm surprised that any web/email host would apply a rule intended for a personal email account to a listserve. I'm guessing that you are running MailMan on your own computer, then using mail server provided by your email hosting company to send the messages. So to the email host, you do look like a very busy personal account. 

As I see it, your options include:

* Discuss this limitation with your email host & see if they will waive the message sending cap for your listserv.
* Use a mailman installation hosted by your email hosting company, which is not subject to a message sending cap. 
* Changing email hosts & using a mailman installation hosted by your email hosting company, which is not subject to a message sending cap. 

No need to change registrars. NameCheap is a good registrar, better than many. I haven't used their web/email hosting. 

My email lists are all running on Mailman provided by my email host. You don't even need to install it, just choose a dedicated subdomain for it to run on. They do NOT limit message flow from Mailman, although they do limit the number of messages per hour sent from a personal mail account. No web/email host is perfect, but I'm pretty happy with DreamHost. Especially for about $100 a year for more services than I can possibly use. (And I'm giving it a good go!). 

Here is a Dreamhost Coupon code & link that will give you $10 off now, plus 1 free LIFETIME domain registration. So that's a savings of about $11 a year for life. MACMEDIXFREEDOM  What else is included? Tons! Check it out.
