@Patch and @lubos As an IT technician, I will add my two cents to the thoughts on this issue.
I allow pdf attachments in email, because while they are not 100% safe from malware etc, pdf is the de facto standard for sending any attachments nowadays. So pdf’s go through the mail server automatically, although there is the ability to disable activex and macro support within pdf’s on computers.
Both Html and rtf attachments however are blocked attachments by default because both can and often are compromised by malware or viruses to infect networks. So using html or rtf as an attachment in an email is a terrible idea. Text is safe, but a very poor format for sending invoices! I would be very suspicious of receiving an attachment in text, html or rtf.
So I would recommend sticking with pdf as the format to send attachments otherwise you will find over the years loads of problems with people having to whitelist your domain or allow those attachments etc. More trouble than it’s worth. Don’t use non standard formats to send invoices. People expect to see your invoice and payslips in pdf format so stick with that.
I appreciate that you are frustrated that with the deprecation of the internal pdf generator you are unable to send invoices and payslips without opening up your accounting program to the Internet.
I would suggest that the customer, and yet to be developed supplier and employee portal address these shortcomings as this is the direction I would go in if I was developing Manager. My expectation is that companies move away from sending attachments via email and move towards portals which is the direction a lot of people are moving in. I am not sure how other accounting programs “generate” the pdf’s from links but it seems to work.
I personally have no issues with removal of the internal pdf generator and in fact support it’s removal to legacy as I agree with the impracticality of the 3rd party addon. It has never generated pdf’s 100 accurately
