%Net.SMTP

class %Net.SMTP extends %Library.RegisteredObject

Send a SMTP mail message

The Charset property of each %Net.MailMessagePart determines the charset for text MIME parts. The charset property is ignored unless ContentType=text/... Charset sets the Character Set for the content-type header. IMPORTANT: Charset must be set before any data is written to the TextData stream associated with this %Net.MailMessagePart. The Charset may also be initialized when the message is created by ##Class(%Net.MailMessagePart).%New(charset) or ##Class(%Net.MailMessage).%New(charset). For Unicode locale the default Charset for ##Class(%Net.SMTP).%New() is utf-8 and for 8-bit locale it is the default Cache charset.

Parameters

parameter Base64Seq = ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/;
parameter PrintableAscii = !""#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~;

Properties (Including Private)

property AllowHeaderEncoding as %Boolean [ InitialExpression = 1 ];
If true, the Send() method will encode non-ASCII header text according to the rules specified by RFC 2047. This is the default. Some mail readers do not accept the encoding specified by RFC 2047 and thus we allow disabling this encoding by setting AllowHeaderEncoding=false.
Property methods: AllowHeaderEncodingDisplayToLogical(), AllowHeaderEncodingGet(), AllowHeaderEncodingIsValid(), AllowHeaderEncodingLogicalToDisplay(), AllowHeaderEncodingNormalize(), AllowHeaderEncodingSet()
property AuthFrom as %String (MAXLEN = 255, TRUNCATE = 1);
AuthFrom specifies the address to be used for the AUTH parameter of the MAIL FROM SMTP command for SMTP authenticated session. If specified, this property will be the argument of the AUTH= extension to the MAIL FROM command. This property may be specified as "<>" to indicate that the original submitter of the messge is not known.
Property methods: AuthFromDisplayToLogical(), AuthFromGet(), AuthFromIsValid(), AuthFromLogicalToDisplay(), AuthFromLogicalToOdbc(), AuthFromNormalize(), AuthFromSet()
property ContinueAfterBadSend as %Boolean [ InitialExpression = 0 ];
If true, sending the email will continue if a send fails and failed email addresses will be added to the FailedSend list.
Property methods: ContinueAfterBadSendDisplayToLogical(), ContinueAfterBadSendGet(), ContinueAfterBadSendIsValid(), ContinueAfterBadSendLogicalToDisplay(), ContinueAfterBadSendNormalize(), ContinueAfterBadSendSet()
property Debug as %Integer [ InitialExpression = 0 ];
Property methods: DebugDisplayToLogical(), DebugGet(), DebugIsValid(), DebugLogicalToDisplay(), DebugNormalize(), DebugSet()
property Error as %String (MAXLEN = 255, TRUNCATE = 1);
If Send is called and returns an error status, the error message is in the Error property.
Property methods: ErrorDisplayToLogical(), ErrorGet(), ErrorIsValid(), ErrorLogicalToDisplay(), ErrorLogicalToOdbc(), ErrorNormalize(), ErrorSet()
property FailedSend as list of %String (MAXLEN = 8000, TRUNCATE = 1);
A list of email addresses for which the Send failed. If the Send for any address is successful, then a %Status of $$$OK is returned by Send and this list contains any failed addresses. If Send is not successful for any email address, then an %Status of $$$SMTPNoSend and all address on this list. Use (sender.FailedSend.Count()=0) to test if all sends succeeded.
Property methods: FailedSendBuildValueArray(), FailedSendCollectionToDisplay(), FailedSendCollectionToOdbc(), FailedSendDisplayToCollection(), FailedSendDisplayToLogical(), FailedSendGet(), FailedSendGetObject(), FailedSendGetObjectId(), FailedSendGetSwizzled(), FailedSendIsValid(), FailedSendLogicalToDisplay(), FailedSendLogicalToOdbc(), FailedSendNormalize(), FailedSendOdbcToCollection(), FailedSendSet(), FailedSendSetObject(), FailedSendSetObjectId()
property SSLCheckServerIdentity as %Boolean [ InitialExpression = 0 ];
When making an SSL connection check the server identity in the server certificate matches the name of the system we are connecting to. This defaults to being on and matches based on the rules layed out in section 3.1 of RFC 2818.
Property methods: SSLCheckServerIdentityDisplayToLogical(), SSLCheckServerIdentityGet(), SSLCheckServerIdentityIsValid(), SSLCheckServerIdentityLogicalToDisplay(), SSLCheckServerIdentityNormalize(), SSLCheckServerIdentitySet()
property SSLConfiguration as %String;
The name of the activated TLS/SSL configuration to use for smpts requests.
Property methods: SSLConfigurationDisplayToLogical(), SSLConfigurationGet(), SSLConfigurationIsValid(), SSLConfigurationLogicalToDisplay(), SSLConfigurationLogicalToOdbc(), SSLConfigurationNormalize(), SSLConfigurationSet()
property ShowBcc as %Boolean;
If ShowBcc = true (1), then Bcc headers will be written to the email message. The Bcc headers will usually be filtered out by the SMTP server.
Property methods: ShowBccDisplayToLogical(), ShowBccGet(), ShowBccIsValid(), ShowBccLogicalToDisplay(), ShowBccNormalize(), ShowBccSet()
property UseSTARTTLS as %Boolean;
If true then the STARTTLS extension to SMTP (RFC 3207) should be used to authenticate to the SMTP server on the normal SMTP port. The SSLConfiguration must be specified.
Property methods: UseSTARTTLSDisplayToLogical(), UseSTARTTLSGet(), UseSTARTTLSIsValid(), UseSTARTTLSLogicalToDisplay(), UseSTARTTLSNormalize(), UseSTARTTLSSet()
property authenticator as %Net.Authenticator;
To do SMTP authentication with the SMTP server (as defined by RFC 2554), instantiate a %Net.Authenticator object, set UserName and Password properties of the authenticator and assign it to this property. An example of the use of authenticator follows.
  #include %occOptions
  #include %occStatus

Methods (Including Private)

private method EncodeHeaderPart(header As %String, part As %String, addr As %String, first As %Boolean, termChar As %String, sepChar As %String = " ") as %String
method EncodeXtext(text As %String) as %String
xtext encoding is defined in RFC 1891 as:

"xtext" is formally defined as follows:
xtext = *( xchar / hexchar )
xchar = any ASCII CHAR between "!" (33) and "~" (126) inclusive, except for "+" and "=".
;"hexchar"s are intended to encode octets that cannot appear
;as ASCII characters within an esmtp-value. hexchar = ASCII "+" immediately followed by two upper case hexadecimal digits

method Login(ByRef authenticated As %Boolean)
Setup session with the SMTP server. We will use the EHLO command and SMTP authentication as supplied by the authenticator property where possible. If EHLO is not accepted or authentication fails, we will attempt to use the HELO command.
method Send(msg As %Net.MailMessage) as %Status
Used to send msg to SMTP server.

Returns a %Status to indicate success or failure.

The send() supports the following small subset of permissible message header fields. Set the corresponding MailMessage properties before invoking send.

  • Date - set from msg.Date; will be set to the current date and time if not specified
  • From - set from msg.From
  • Subject - set from msg.Subject
  • To - set from msg.To by converting to "," separated list
  • Cc - optionally set from msg.Cc by converting to "," separated list
  • Bcc - optionally set from msg.Bcc by converting to "," separated list
  • Sender - optionally set from msg.Sender
  • Reply-To - optionally set from msg.ReplyTo

The "MAIL FROM:" SMTP command uses the Sender field if specified, otherwise the From field.
The "RCPT TO:" SMTP command uses the To and Cc lists joined by commas.
simple e-mail address must be passed to MAIL and RCPT. Therefore if the address is of the form name <email>, the value passed to the SMTP command is just email.

method zone() as %String
Return timezone converted to RFC822 format
private method zzErrorTrap() as %String
Error trap
