Hi,

I've been using your package for a while to send emails with HTML body and PDF attachments for a while now. I updated R last week and found that the body is now sent as an attachment too...

I assume that somewhen recently the disposition argument to mime_part has stopped working correctly?

This is essentially the code i've been using...

sendmailR::sendmail(from = address,
                      to = recipient,
                      subject = subject,
                      msg = list(sendmailR::mime_part(emailbody,
                                                      type = "text/html",
                                                      disposition="inline"),
                                 sendmailR::mime_part(pdfoutfile,
                                                      name = pdf_name)),
                      control = smtp_settings)

Hi,

I'm using your package for sending emails to a database of customers. I'd like to have the name of the sender (From parameter) appear in the customer's inbox but I can't seem to make it work. If I use only the sender's email address then it works fine.
This is what I've tried so far:

• "\"Name Sender\" <[email protected]>"

• '"Name Sender" <[email protected]>'

• paste0("\"Name Sender\"", "<[email protected]>")

But I keep getting a 501 error from the smtp server. Am I missing something? or is it a problem on the SMTP server itself while handling the message through curl?

Thanks for your help

Hi,

while the method mime_part.character() has a parameter type it is not passed down to .file_attachment() in https://github.com/olafmersmann/sendmailR/blob/main/R/mime_part.R#L210:

> attachment <- sendmailR::mime_part("/etc/group", "group", type = "text/plain") 
> attachment$headers$`Content-Type`
[1] "application/octet-stream"

vs.

> attachment2 <- sendmailR:::.file_attachment("/etc/group", "group", type = "text/plain")
> attachment2$headers$`Content-Type`
[1] "text/plain"

I didn't open a PR because it's not completely obvious how to handle this. One idea would be to use the package mime to guess the MIME type of the file.

The minimum reproducible example:

1. Start a new R session, do the following:
   library(sendmailR)
sendmail(from = "<[email protected]>", to = "<[email protected]>", subject = "Test", msg = mime_part("Body text"), control=list(smtpServer="ASPMX.L.GOOGLE.COM", smtpPort="25"))
   Email will be sent successfully.
2. Set options(encoding = "UTF-8") and try to send email from 1 once again. Result: Error in if (code == lcode) { : argument is of length zero mistake appears.

My default language settings are "English_United States.1252".

Hi Olaf! Thank you for you work developing this package.
I encouneterd an issue when implementing package for sending reports.
I wrote a piece of code that worked perfectly well at 11:00
The same piece of code end stopped working with the following error today at 13:00:

Error in curl_fetch_memory(smtp_server, handle = h) :
schannel: next InitializeSecurityContext failed: SEC_E_CERT_EXPIRED (0x80090328)

Could you please help with this.
