Setup / Reference Data > gb_controls

Module	Control	Value	Description
gb	mail_transmission_provider	smtp	Choose which emailing protocol you want to use to send emails. You can either use 1. 'ses' - Amazon Simple Email Service (SES). This is the recommended method. You will need to set up a DKIM key to verify the email's domain. 2. 'smtp' - For Simple Mail Transfer Protocol (SMTP). You will need to set up an SPF record to verify the email's domain. The Catch-e System was developed to use only SMTP at first. SES was introduced later and is now our recommended protocol for clients
gb	mail_sender_domains_enforcing_flag	yes	Set to 'yes' to control the status of Domain enrolling of SPF Records
gb	email_attachments_max_size_in_bytes	7864320	Your emails will switch to a URL link if the combined size of the attached files is larger than the specified maximum size. We recommend a maximum of '7864320' as the Amazon SES feature enforces a mail size limit of 10MiB. If this control is set to a higher value, emails will fail if the size limit of 10MiB is exceeded. If you are using SMTP, this can be set to a higher value if desired. Note: Amazon SES converts the attached files to a binary file before attaching it to the email which can increase in size when converted. For example: a file of size 7.5 MB when converted can go over 10MiB, hence we recommend using maximum of '7864320' so the file is still less than 10MiB in size after conversion to binary file
