    How many email accounts can be assigned per user in Pharos MobilePrint 2.1?

    Chris Axtell Navigator

      For Pharos MobilePrint 2.0 there was a hard limit of 255 characters, with multiple addresses being allowed as comma separated values. There was some lively discussion (see Using multiple email accounts in Pharos MobilePrint 2.0) regarding this topic.

       

      In the MobilePrint 2.0 Installation and Configuration Guide for Uniprint.pdf document there was on page 54 the following statement:

       

      How many email addresses can a user register with MobilePrint?

      [...] Moreover, a Uniprint administrator can add multiple email address in the users > Accounts Context of Pharos Administrator. A user can have as many email addresses as can fit in 255 characters.

       

      However, in the MobilePrint 2.1 Installation and Configuration Guide for Uniprint.pdf document the above statement has been removed. Searching through most of the other documentation regarding both Uniprint and MobilePrint, as well as this Community there doesn't appear to be any new statement regards the maximum number and/or character length allowed for the data stored in the email field. The electronic Uniprint documentation simply states the following:

       

      Email: The Email address for the user. As of Uniprint 9.0, the Pharos Administrator accepts entry of multiple email addresses, separated by commas.

       

      Considering that an email address's maximum practical length is 254 characters, what is the current limit supported by Pharos for the number of email addresses assigned per user? Or if there is still a character limit what is it?

       

      Thanks,

      Chris

          The limit supported for the number of email addresses assigned per user is still a character limit. In general, it would be around 8 -12 email accounts assigned per user. However, it also depends on the length of an email account.

              Hi Brenda,

               

              Unfortunately the answer of "8-12 email accounts per user" is a pretty nebulous answer when someone is looking at automated provisioning. At least in the documentation for the previous version it specified the exact limit of 255 characters. The documentation for the newer version completely removes all mention of a limit, so it could be be implied that there is no limit to the number of address that can be populated in the field. Hence the reason for posting this question...

               

              According to the specs for an email addresses, a valid address can effectively be up to 254 characters. If Pharos still has the 255 character limit then the practical number of address is anywhere from 1 - 12 addresses depending upon the length. With the limit being 255 characters, not 8-12 email addresses.

               

              I'll accept Pharos having a limit in the number of email addresses that can be associated with an account. However, I do desire to know exactly what type of limit it is, as well as what the value is. Per your response we know the limit type is still a character length. So what is the actual limit value in number of characters? Is it still 255, or has this been increased?

               

              As a side topic, why was 255 characters originally selected as the character limit? Especially when in some cases it may only barley hold a single email address? Wouldn't a character limit around 510 or 1020 be a better value?

               

              Thanks,

              Chris

                  Chris,

                   

                  The character limit on the Email field is 255.  The reason is it that way is because the use-cases we anticipated in design were that a user would only need to register 1 - 3 email addresses for use with the product.  With an average email address length being around 20-25 characters, that leaves room for about 8 -12 average email addresses, comma-separated.  It seems that some customers, such as yourself, have a configuration that exceeds this character limit, so we will need to consider that in future product updates.

                      Hi Jeff,

                       

                      Thanks for the response confirming the limit is still set to 255 characters. That's what we thought; however, we wanted to confirm the limit remained unchanged since the latest version of the documentation removed the reference to the limit.

                       

                      I'd agree that for most groups the 255 characters seems like a large practical limit based on an average email length of 20-25 characters. One use case where this small limit would cause problems is when an organization is transitioning their email domains. During the transition window to provide seamless interaction for patrons it would be necessary to pre-populate both the "old" and "new" email domain and all the associated "vanity" email aliases that patrons may have elected to create for themselves. Another use case is where an organization has multiple "sub-groups" each with their own email domains. Combine multiple email domains with the possibility of patron generated "vanity" email aliases and the 255 character limit becomes limiting rather quickly.

                       

                      Again thanks Brenda and Jeff for your time.
